The difference between Calayer and UIView

The main expression of this article is the difference between these two classes and a small number of links.

1. The first thing to be clear is that Calayer inherits from NSObject, and UIView is integrated from Nsresponder. So uiview can be the corresponding user's Click event, and Calayer more is to do rendering and animation effects.

2. The second is that both Calayer and UIView can be displayed on the screen. What's the difference? Of course! Each uiview that is displayed on the page is drawn on its own root layer! It's like a layer is an artboard, and view is a brush.

3. The third is that both of them have no significant difference in the efficiency of their presentation. However, it is still recommended to use DrawRect in Tableviewcell instead of subviews to draw the cell.
