plugable displaylink

BeforeWaiting and Exit events. When a touch event arrives, the RunLoop is awakened and the code in the App performs some operations, for example, creating and Adjusting view levels, setting the frame of UIView, modifying the transparency of CALayer, and adding an animation to the view are all ultimately marked by CALayer, and submit it to an intermediate state through CATransaction. When all the above operations are completed and RunLoop is about to sleep (or quit), the Observer that follows th
