Advanced iOS scripting

Device properties

There are a number of device-specific properties that you can access. See the script reference pages for:

Anti-piracy check

A common way of hacking an application is by removing the AppStore DRM protection and then redistributing it for free. Use Unity’s anti-piracy check to find out if your application was altered after it was submitted to the AppStore.

Check if your application is genuine (not hacked) with the Application.genuine property. If the property returns false, you can warn users they are using a hacked app, or you can disable certain functions.

Note: Use Application.genuineCheckAvailable along with Application.genuine to verify application integrity. Because accessing the Application.genuine property is a resource-intensive operation, you shouldn’t perform it during frame updates or other time-critical code.

Vibration support

You can trigger a vibration by calling Handheld.Vibrate. Devices without vibration hardware ignore this call.

Activity indicator

Mobile operating systems have built-in activity indicators you can use during slow operations. See Handheld.StartActivityIndicator docs for examples.

Screen orientation

You can control the screen orientation of your application on both iOS and Android devices. By detecting a change in orientation or forcing a specific orientation, you can create app behaviors that depend on how the user holds the device.

To retrieve device orientation, access the Screen.orientation property. Orientation can be one of the following:

Идентификация Behavior
Portrait Устройство в портретном режиме, удерживающееся в вертикальном положении. Кнопка “домой” расположена снизу.
PortraitUpsideDown Устройство в портретном режиме, но “вверх ногами”, удерживающееся в вертикальном положении. Кнопка “домой” расположена сверху.
LandscapeLeft Устройство в ландшафтном режиме, удерживающееся в вертикальном положении. Кнопка “домой” расположена справа.
LandscapeRight Устройство в ландшафтном режиме, удерживающееся в вертикальном положении. Кнопка “домой” расположена слева.

Set Screen.orientation to one of the above orientations or use ScreenOrientation.AutoRotation to control the screen orientation. When you enable auto-rotation, you can still disable some orientations on a case-by-case basis.

For more information, see the following API documentation:

Determining device generation

Different device generations have varied performance and support different functionalities. Use the iOS.DeviceGeneration property to query the device’s generation.

Display cutout

On some displays, certain areas of the screen might be obscured or non-functional because of other hardware occupying that space. Use Screen.cutouts to return a list of bounding boxes surrounding each cutout.

iOS devices do not provide a native API to get the display cutout information, so the cutouts are hardcoded in the Xcode project for each available iOS device. You can modify existing data or add additional devices in the Unity Xcode project ReportSafeAreaChangeForView function, which is in the file.

Recording a replay of your game

You can use ReplayKit to record the audio and video of your game, along with audio and video commentary captured from the device’s microphone and camera.
