UIview需要知道的一些事情：setNeedsDisplay、setNeedsLayout
setNeedsDisplay、setNeedsLayout
1、在Mac OS中NSWindow的父类是NSResponder，而在i OS 中UIWindow 的父类是UIVIew。程序一般只有一个窗口但是会又很多视图。
2、UIView的作用：描画和动画，视图负责对其所属的矩形区域描画、布局和子视图管理、事件处理、可以接收触摸事件、事件信息的载体、等等。

3、UIViewController 负责创建其管理的视图及在低内存的时候将他们从内存中移除。还为标准的系统行为进行响应。

4、layOutSubViews 可以在自己定制的视图中重载这个方法，用来调整子视图的尺寸和位置。

5、UIView的setNeedsDisplay和setNeedsLayout方法。首先两个方法都是异步执行的。而setNeedsDisplay会调用自动调用drawRect方法，这样可以拿到UIGraphicsGetCurrentContext，就可以画画了。而setNeedsLayout会默认调用layoutSubViews，就可以处理子视图中的一些数据。
宗上所诉，setNeedsDisplay方便绘图，而layoutSubViews方便出来数据
