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));
    }
}
