Remarks
When you want to use one of the CALayer subclasses as your UIView's backing layer, you need to add the following code snippet to your class:
class MyView : UIView {
//
// This instructs the runtime that whenever a MyView is created
// that it should instantiate a CAEAGLLayer and assign that to the
// UIView.Layer property
//
[Export ("layerClass")]
public static Class LayerClass () {
return new Class (typeof (CAEAGLLayer));
}
}
