iOS Player 設定

このページでは、iOS 特有の Player 設定について説明します。すべてのプラットフォームに適用される一般的な Player 設定については、Player - General settings を参照してください。

以下のセクションのプロパティが説明されています。

• Icon (アイコン)
• Resolution and Presentation (解像度と表示)
• Splash Image (スプラッシュ画像)
• Debugging and crash reporting (デバッグとクラッシュのレポート)
• Other Settings (その他の設定)

Icon

Icon 設定を使用して、Apple Store でのアプリケーションのブランド設定をカスタマイズします。

iOS デバイス (iPhone、iPad) ごとに以下のタイプのカスタムアイコンをアップロードして割り当てることができます。

Icon type	Where it displays
Application icons	Main icons for your app
Spotlight icons	Spotlight search results for your app
Settings icons	Device’s main Settings page
Notification icons	Notifications sent from your app
Marketing icons	App Store

アップロードするすべてのアイコンは Texture 2D タイプのアセットです。アイコンのテクスチャがない場合、Unity はアイコンのテクスチャを最も近いサイズで拡大し、より大きなテクスチャを使用するようにします。

Resolution and Presentation

Resolution and Presentation (解像度と表示) セクションを使用して、画面の表示をカスタム化します。

これらの設定は、以下のカテゴリに分類されます。

• Resolution Scaling (解像度スケール)
• Orientation (向き)
• Allowed Orientations for Auto Rotation (自動変更の向き)
• Multitasking Support (マルチタスクサポート)
• Status Bar (ステータスバー)

Resolution Scaling

Resolution Scaling Mode 設定を使用して、 スケールをネイティブの画面解像度以下に設定します。

Setting	Function
Disabled	Scaling doesn’t apply and the application renders to its native screen resolution.
FixedDPI	When you select this value, the Target DPI property appears. Use the Target DPI property to set the target DPI of the game screen. Unity downscales the game screen to match this setting if the device’s native screen DPI is higher than this value. This helps you optimize performance and battery life. You can also use it to target a specific DPI setting. Unity calculates the scale as min(Target DPI * Factor / Screen DPI, 1). The Factor uses the Resolution Scaling Fixed DPI Factor value you enter in the Quality settings.
Reset resolution on window resize	Indicates whether to set the screen resolution to the new native window size when the native window size changes. If you set Resolution Scaling Mode to Fixed DPI, Unity recalculates the resolution based on Fixed DPI property.

Orientation

Default Orientation ドロップダウンからゲームの画面の向きを選択します。デフォルト設定は Auto Rotation です。選択すると、デバイスの向きに合わせて画面が回転します。

他の設定を選択すると、画面上のホームボタンの固定位置を決定します。

設定	ホームボタンの位置
Portrait	下
Portrait Upside Down	上
Landscape Left	右
Landscape Right	左
Auto Rotation	画面の向きはデバイスの向きに応じて変化します。これがデフォルトです。

ノート: Default Orientation 設定は iOS と Android デバイスの両方に適用されます。

Default Orientation として Auto Rotation を選択すると、以下の設定が表示されます。

設定	機能
Use Animated Autorotation	これを有効にすると、ユーザーがデバイスを回転させるときに、画面の回転にアニメーションによる遷移が使用されます。そうでない場合は、画面の回転は即座に変化します。
Allowed Orientations for Auto Rotation	Auto Rotation は画面の向きをデバイスに合わせて変更します。許可する画面の向きを制限したい場合 (例えば、 デバイスを横向きにロックしたいなど) は、許可したい向きのチェックボックスをオンにします。

Multitasking Support

アプリケーションをフル画面モードで実行する必要がある場合は、Requires Fullscreen オプションを有効にします。

Status Bar

Status Bar セクションを使用して、iOS ステータスバーに関連するパラメーターを指定します。

Setting	Function
Status Bar Hidden	Enable this option to hide the status bar when your application launches.
Status Bar Style	Define the style of the status bar when the application launches. The options are Default and Light.
Disable Depth and Stencil	Enable this option to disable the depth and stencil buffers.
Render Over Native UI	Enable this option to force your app to render on top of the native iOS UI.
Show Loading Indicator	Select how the loading indicator appears. The options are White Large, White, and Gray.

Splash Image

Splash Image セクションを使用して、iOS がサポートするさまざまなデバイス用にアプリケーションのスプラッシュ画像をカスタマイズします。

共通の Splash Screen 設定 の上にある Virtual Reality Splash Image 設定では、VR ディスプレイのカスタムのスプラッシュ画像を選択できます。　

カスタムストーリーボード

iPhone または iPad の Launch screen type ドロップダウンで、Custom Storyboard (カスタムストーリーボード) オプションを選択すると、Custom Storyboard ボタンが表示されます。

Click the Custom Storyboard button to select a storyboard to display when your game starts up on the device. For your storyboard to appear here, you must first create the storyboard in Xcode and copy it to your Project. For more information, see Apple developer documentation about storyboards, scenes, and connections.

Use Storyboard for Launch Screen チェックボックスを無効にする場合は、以下のいずれかの方法でスプラッシュ画像を実装できます。

カスタムストーリーボードを使用しない場合は、Unity のビルトイン起動スクリーンを使ってスプラッシュ画像を実装できます。

Launch Screen

Launch Screen (起動画面) は、iOS がデバイスでスプラッシュスクリーンを作成するストーリーボードファイルです。以下の制限があります。

• iPad のデバイスの向きに基づいて異なるコンテンツをディスプレイすることはできません。
• All iPhones support landscape launch screens, but certain iOS versions display the Landscape Left launch screen instead of the Landscape Right one due to a bug.
• iOS 13 以前はストーリーボードのルートビューコントローラーをオーバーライドすることができませんでした。そのため、起動画面はすべての向きをサポートし、ステータスバーの動作など、いくつかの UI 設定を無視していました。iOS 13 からは、起動画面は向きやステータスバーの外観に関するアプリケーションの設定に完全に準拠するようになりました。

これらの制限は、カスタムストーリーボードにも適用されます。

Select the Launch screen type for iPhone and iPad in the iPhone Launch Screen and iPad Launch Screen sections:

値		機能
Default		When you select this option, Unity adds a solid blue-black image that’s the same color as the background for Unity’s default splash screen. The image is used for both portrait and landscape orientations, and displays using aspect-fill mode.
None		Apple no longer supports Launch Images. This option exists for backwards compatibility reasons. If you select it, your project will use Unity’s default splash screen instead.
Image and background (relative size)		Displays an image in the center of the screen and fills the remaining area with a solid color.
	Portrait Image	Select an image for portrait orientation.
	Landscape Image	Select an image for landscape orientation.
	Background Color	Select a background color to fill any screen space that the image doesn’t cover.
	Fill percentage	Specify image size as a percentage of the screen size. Unity calculates image size based on the length or width of the screen, whichever one is smaller (vertical for landscape displays, horizontal for portrait ones).
Image and background (constant size)		Displays an image in the center of the screen and fills the area with a solid color. This has the same options as Image and background (relative size), except that you specify image size in points rather than as a percentage. Tip: Points and pixels aren’t the same. A pixel (px) is a single dot in your image. A point (pt) is a unit of length that measures 1/72th of an inch. Pixel sizes are relative to the screen size and resolution, while point sizes are the size on any screen. For more information, see W3C guidance on size units.
Custom XIB		When you select this option, the Custom XIB button appears. Click the button to select a custom XIB file to use as a loading screen.
Custom Storyboard		When you select this option, the Custom Storyboard button appears. Click the button to select a custom Storyboard file to use as a loading screen.

ノート: Unity Personal のサブスクリプションでは、選択したスプラッシュスクリーンに加えて、エンジンが初期化されるとすぐに Unity スプラッシュスクリーン が表示されます。

Debugging and crash reporting

Debugging and crash reporting の設定を使用して、アプリケーションのパフォーマンスに関するデータを収集し、クラッシュをトラブルシューティングします。

Setting	Function
Enable Internal Profiler (Deprecated)	This feature is deprecated and will be retired in a future version of Unity. Use the Profiler window instead (menu: Window > Analytics > Profiler). The Profiler collects application performance data and prints a report to the console. The report contains the number of milliseconds each Unity subsystem takes to execute on each frame, averaged across 30 frames.
On .Net UnhandledException	Select the action Unity takes when a .NET unhandled exception occurs. The options are Crash (the app crashes and generates a crash report, which users can submit to iTunes and developers can use to troubleshoot the crash), or Silent Exit (the application exits with no errors and doesn’t generate a crash report).
Log Obj-C Uncaught Exceptions	When you enable this action, Unity prints Objective-C Uncaught Exception information to the console.
Enable Crash Report API	Enables a custom crash reporter to capture crashes. You can use scripts to access crash logs via the CrashReport API.

Other settings

Other Settings セクションでさまざまな Player 設定を行うことができます。これらのオプションは、以下のグループに分類されています。

• Logging (ログ)
• Legacy (古い機能)

Rendering

これらの設定を使用して、iOS プラットフォーム用にゲームをレンダリングする方法をカスタマイズします。

Setting		Function
Color Space		Choose which color space Unity uses for rendering: Gamma or Linear. For more information, see Linear rendering overview. Gamma: Gamma color space is typically used for calculating lighting on older hardware restricted to 8 bits per channel for the frame buffer format. Even though monitors today are digital, they might still take a gamma-encoded signal as input. Linear: Linear color space rendering gives more precise results. When you select to work in linear color space, the Editor defaults to using sRGB sampling. If your Textures are in linear color space, you need to work in linear color space and disable sRGB sampling for each Texture.
Color Gamut		You can add or remove color gamuts for the iOS platform to use for rendering. Click the plus (+) icon to see a list of available gamuts. A color gamut defines a possible range of colors available for a given device (such as a monitor or screen). The sRGB gamut is the default (and required) gamut. When targeting recent tvOS devices with wide color gamut displays, use DisplayP3 to use the full display capabilities. Use Metal Editor Support as a fallback for older devices.
Multithreaded Rendering		Enable this option to move graphics API calls from Unity’s main thread to a separate worker thread. This can help to improve performance in applications that have high CPU usage on the main thread.
Static Batching		Use Static batching. For more information, refer to Draw call batching.
Dynamic Batching		Use dynamic batching (enabled by default). For more information, refer to Draw call batching. Note: Dynamic batching has no effect when a Scriptable Render Pipeline is active, so this setting is only visible if the Scriptable Render Pipeline Asset Graphics setting is blank.
Sprite Batching Threshold		Controls the maximum vertex threshold used when batching.
Compute Skinning		Enable this option to use Metal GPU compute skinning, which frees up CPU resources. To learn more about GPU compute skinning, see the Wikipedia page on skeletal animation.
Graphics Jobs (Experimental)		Enable this option to instruct Unity to offload graphics tasks (render loops) to worker threads running on other CPU cores. This reduces the time spent in Camera.Render on the main thread, which is often a bottleneck. Note: This feature is experimental. It might not deliver a performance improvement for your Project, and might introduce instability.
Texture compression format		Choose between ASTC and PVRTC as the default texture compression format for iOS. Check the texture compression format overview for more information.
Normal Map Encoding		Choose XYZ or DXT5nm-style to set the normal map encoding. This affects the encoding scheme and compression format used for normal maps. DXT5nm-style normal maps are of higher quality, but more expensive to decode in shaders.
Lightmap Encoding		Defines the encoding scheme and compression format of the lightmaps. You can choose from Low Quality, Normal Quality, or High Quality.
HDR Cubemap Encoding		Defines the encoding scheme and compression format of the HDR Cubemaps. You can choose from Low Quality, Normal Quality, or High Quality.
Lightmap Streaming		Uses Mipmap Streaming for lightmaps. Unity applies this setting to all lightmaps when it generates them. Note: To use this setting, you must enable the Texture Streaming Quality setting.
Streaming Priority		Sets the priority for all lightmaps in the Mipmap Streaming system. Unity applies this setting to all lightmaps when it generates them. Positive numbers give higher priority. Valid values range from –128 to 127.
Frame Timing Stats		Allows Unity to gather CPU/GPU frame timing statistics. Use this option with the Dynamic Resolution camera setting to determine if your application is CPU or GPU bound.
Virtual Texturing		Currently not supported on iOS.
Shader precision model		Controls the default precision of samplers used in shaders. For more information, see Shader data types and precision.
360 Stereo Capture		Currently not supported on iOS.
Load/Store Action Debug Mode		Highlights undefined pixels that might cause rendering problems in your built application. The highlighting appears only in the Game view, and your built application if you select Development Build in Build Settings. See LoadStoreActionDebugModeSettings.
	Editor Only	Highlights undefined pixels in the Game view, but not in your built application.

Identification

アプリケーションの識別情報を入力します。

設定	機能
Override Default Bundle Identifier	Indicates whether you can manually set the bundle identifier. Note: This setting affects macOS, iOS, tvOS, and Android.
Bundle Identifier	Enter the provisioning profile of the application you are building. The basic structure of the identifier is com.CompanyName.ProductName. This structure might vary based on which country you live in, so always default to the string Apple provides to you for your Developer Account. Your ProductName is set up in your provisioning certificates. The Bundle Identifier must follow the convention com.YourCompanyName.YourProductName and must contain only alphanumeric and hyphen characters. For more information, see CFBundleIdentifier. Important: Unity automatically replaces any invalid characters you type with a hyphen. To set this property, enable Override Default Bundle Identifier.
Version	バンドルの “リリース-バージョン-番号” の文字列を入力します (例えば、4.3.6)。 関連する info.plist ファイルに CFBundleShortVersionString として表示されます。詳しくは、Apple 開発者用ドキュメントの CFBundleShortVersionString を参照してください。
Build	アプリケーションのこのバージョンのビルド番号を入力します。関連する info.plist ファイルに CFBundleVersion として表示されます。詳しくは、Apple 開発者用のドキュメントで CFBundleVersion を参照してください。
Signing Team ID	Apple Developer Team ID を入力します。詳しくは、Apple 開発者用ウェブサイトの Xcode ヘルプ を参照してください。これにより、生成された Xcode プロジェクトの Team ID が設定され、開発者は Build and Run 機能を使用できるようになります。アプリケーションの自動署名のためには Apple Developer Team ID をここに入力する必要があります。 詳細は、Creating Your Team Provisioning Profile を参照してください。
Automatically Sign	これを有効にすると、Xcode によってビルドに自動的に署名されます。

• E： その他の設定

API設定

Setting		Function
Scripting Backend		The scripting backend determines how Unity compiles and executes C# code in your Project. This setting defaults to IL2CPP for iOS and can’t be changed. IL2CPP compiles C# code into CIL, converts the CIL to C++, and then compiles that C++ into native machine code, which executes directly at run time. For more information, see documentation on IL2CPP. C++ code generated by the IL2CPP scripting backend can be updated incrementally, which allows incremental C++ build systems to compile only the changed source files. This can significantly lower iteration times.
API Compatibility Level		Choose which .NET APIs you can use in your project. This setting can affect compatibility with 3rd-party libraries. However, it has no effect on Editor-specific code (code in an Editor directory, or within an Editor-specific Assembly Definition).
	.Net Standard 2.0	Compatible with .NET Standard 2.0. Produces smaller builds and has full cross-platform support.
	.Net 4.x	Compatible with the .NET Framework 4 (which includes everything in the .NET Standard 2.0 profile as well as additional APIs). Choose this option when using libraries that access APIs not included in .NET Standard 2.0. Produces larger builds and any additional APIs available are not necessarily supported on all platforms. See Referencing additional class library assemblies for more information.
C++ Compiler Configuration		The C++ compiler configuration used when compiling IL2CPP generated code. This setting defaults to Release for iOS and can’t be changed.
Use incremental GC		Uses the incremental garbage collector, which spreads garbage collection over several frames to reduce garbage collection-related spikes in frame duration. For more information, refer to Automatic Memory Management.

API Compatibility Level

You can choose your mono API compatibility level for all targets. Sometimes a third-party .NET library uses functionality that is outside of your .NET compatibility level. If you’re on Windows, you can use the third-party software ILSpy to understand what’s happening and how to fix it. Follow these steps:

1. Install ILSpy for Windows.
2. Drag the .NET assemblies for the API compatibility level that you are having issues with into ILSpy. You can find these under Frameworks/Mono/lib/mono/YOURSUBSET/.
3. サードパーティのアセンブリをドラッグします。
4. サードパーティのアセンブリを右クリックし、Analyze を選択します。
5. In the analysis report, inspect the Depends on section. Anything that the third-party assembly depends on, but that’s not available in the .NET compatibility level of your choice, is highlighted in red.

Apple-specific information

Setting	Function
Allow downloads over HTTP	Indicates whether to allow downloading content over HTTP. The options are Not allowed, Allowed in Development builds only, and Always allowed. The default option is Not allowed due to the recommended protocol being HTTPS, which is more secure.

Accelerometer Frequency	Define how often to sample the accelerometer. You can set the frequency at 15Hz, 30Hz, 60Hz, or 100Hz. Use a lower frequency for better performance. If your app doesn’t use the accelerometer, select Disabled.
Mute Other Audio Sources	Enable this option if you want your Unity application to stop Audio from applications running in the background. Otherwise, Audio from background applications continues to play alongside your Unity application.
Prepare iOS for Recording	Enable this option to initialize the microphone recording APIs. This lowers recording latency, but it also re-routes iPhone audio output via earphones.
Force iOS Speakers when Recording	Enable this option to send the phone’s audio output through the internal speakers, even when headphones are plugged in and recording.
Requires Persistent WiFi	Enable this option to require a Wi-Fi connection. This maintains the active Wi-Fi connection while the app is running.
Supported URL schemes	A list of supported URL schemes. To add new schemes, increase the value of the Size property, then set a reference to the Asset to load in the new Element box that appears.

Additional Compiler Arguments	Adds entries to this list to pass additional arguments to the Roslyn compiler. Use one new entry for each additional argument. To create a new entry, click Add (+). To remove an entry, click Remove (-). When you have added all desired arguments, click Apply to include your additional arguments in future compilations. Click Revert to reset this list to the most recent applied state.
Suppress Common Warnings	Indicates whether to display the C# warnings CS0169 and CS0649.
Allow ‘unsafe’ Code	Enables support for compiling ‘unsafe’ C# code in a pre-defined assembly (for example, Assembly-CSharp.dll). For Assembly Definition Files (.asmdef), click on one of your .asmdef files and enable the option in the Inspector window that appears.
Use Deterministic Compilation	Indicates whether to prevent compilation with the -deterministic C# flag. With this setting enabled, compiled assemblies are byte-for-byte identical each time they are compiled. For more information, see Microsoft’s deterministic compiler option.
Enable Roslyn Analyzers	Indicates whether to compile user-written scripts without Roslyn analyzer DLLs that might be present in your project.

Optimization

Setting		Function
Prebake Collision Meshes		Adds collision data to Meshes at build time.
Keep Loaded Shaders Alive		Indicates whether to prevent shaders from being unloaded. For more information, see Shader Loading.
Preloaded Assets		Sets an array of Assets for the player to load on startup. To add new Assets, increase the value of the Size property and then set a reference to the Asset to load in the new Element box that appears.
AOT compilation options		Additional options for Ahead of Time (AOT) compilation. This helps optimize the size of the built iOS player.
Strip Engine Code		Enable this option if you want the Unity Linker tool to remove code for Unity Engine features that your Project doesn’t use. This setting is only available with the IL2CPP scripting backend. Most apps don’t use every available DLL. This option strips out DLLs that your app doesn’t use to reduce the size of the built Player. If your app is using one or more classes that would normally be stripped out under your current settings, Unity displays a debug message when you try to build the app.
Managed Stripping Level		Chooses how aggressively Unity strips unused managed (C#) code. The options are Minimal, Low, Medium, and High. When Unity builds your app, the Unity Linker process can strip unused code from the managed DLLs your Project uses. Stripping code can make the resulting executable significantly smaller, but can sometimes accidentally remove code that’s in use. For more information about these options and bytecode stripping with IL2CPP, refer to ManagedStrippingLevel.
Script Call Optimization		Choose how to optionally disable exception handling for a speed boost at run time. For more information, see iOS Optimization.
	Slow and Safe	Use full exception handling (with some performance impact on the device when using the Mono scripting backend).
	Fast but no Exceptions	No data provided for exceptions on the device (the app runs faster when using the Mono scripting backend). Note: Using this option with the IL2CPP scripting backend doesn’t impact performance, but it might help avoid undefined behavior on release builds.
Vertex Compression		Sets vertex compression per channel. This affects all the meshes in your project. Typically, Vertex Compression is used to reduce the size of mesh data in memory, reduce file size, and improve GPU performance. For more information on how to configure vertex compression and limitations of this setting, refe to Compressing mesh data.
Optimize Mesh Data		Enable this option to strip unused vertex attributes from the mesh used in a build. This option reduces the amount of data in the mesh, which can help reduce build size, loading times, and runtime memory usage. Warning: If you have this setting enabled, you should remember to not change material or shader settings at runtime. Refer to PlayerSettings.stripUnusedMeshComponents for more information.
Strict shader variant matching		If a shader variant is missing, the editor uses the bright pink error shader whilst displaying an error message in the Console.
Texture MipMap Stripping		Enables mipmap stripping for all platforms. This strips unused mipmaps from Textures at build time. Unity determines unused mipmaps by comparing the value of the mipmap against the Quality Settings for the current platform. If a mipmap value is excluded from every Quality Setting for the current platform, then Unity strips those mipmaps from the build at build time. If QualitySettings.masterTextureLimit is set to a mipmap value that has been stripped, Unity will set the value to the closest mipmap value that has not been stripped.

Logging

特定のコンテキストで許可するログのタイプを選択します。

• Select your preferred stack trace method by enabling the option that corresponds to each Log Type (Error, Assert, Warning, Log, and Exception) based on the type of logging you require. For example:
  
  • ScriptOnly: Logs only when running scripts.
    
  • Full: Logs all the time.
    
  • None: No logs are ever recorded.
    

See stack trace logging for more information.
