Assign a list of icons for the specified platform.
Most platforms support viewing icons in multiple sizes so Unity lets you specify multiple icon textures for each platform.
The list will only be assigned if it has the same length as the list of icon sizes returned by GetIconSizesForTargetGroup
and if the specified platform is supported in this editor. By default it sets all available icons for a specified platform unless an IconKind value is specified.
Currently only iOS supports icons which have a different kind than IconKind.Application. Icons assigned to IconKind.Application, IconKind.Settings, IconKind.Notification & IconKind.Spotlight are copied to the appropriate slots in the generated Xcode project.
Calling SetIconsForTargetGroup with an empty Texture2D array removes all icons currently set for all IconKind.
