The difference between UIView and Calayer

1, UIView compared to calayer the biggest difference is UIView can respond to user events, and Calayer not. UIView focuses on the management of display content, and Calayer focuses on drawing content. 2, UIView and calayer are interdependent relationships. UIView relies on content provided with Calayer, Calayer relies on the container provided by UIView to display the content being drawn. In the final analysis Calayer is the basis of all this, if no calayer,uiview itself will not exist, UIView is a special calayer implementation, adding the ability to respond to events. 3, UIView from Calayer, higher than Calayer, is calayer high-level implementation and encapsulation. All features of the UIView are derived from Calayer support.
