UIkit框架之Uivew
1.继承链：UIresponder：NSObject
2.通过使用 addGestureRecognizer:方法可以为视图添加手势
3.下面的属性都可以用来用于动画
4.子视图一般用来进行覆盖的方法：
(1)initWithFrame:一般用来初始化一个UI控件，位置和大小
(2)initWithCoder:使用这个方法来载入你的nib file文件到interface builder中
(3)layerClass:不知道怎么翻译 Implement this method only if you want your view to use a different Core Animation layer for its backing store.
(4)drawRect:一般用来绘制你的自定义视图内容
(5)drawRect:forViewPrintFormatter:当你想在你的自定义视图中定义不同的视图内容可以重载这个方法
(6)requiresConstraintBasedLayout:如果你想要正确的约束你的视图可以使用这个方法
(7)updateConstraints:如果你的视图和你的子视图要创建有一个自定义约束可以使用这个方法，应该是用来更新约束的把
(8)alignmentRectForFrame:, frameForAlignmentRect:实现让你的视图如何和其他视图对齐
(9)sizeThatFits: - Implement this method if you want your view to have a different default size than it normally would during resizing operations.
(10)layoutSubviews:使用这个方法来使你的视图更加精确的布局而不使用那些约束
(11)didAddSubview:, willRemoveSubview:可以用来更加或者删除一些视图
(12)willMoveToSuperview:, didMoveToSuperview - Implement these methods as needed to track the movement of the current view in your view hierarchy.
(13)willMoveToWindow:, didMoveToWindow - Implement these methods as needed to track the movement of your view to a different window.
(14)touchesBegan:withEvent:, touchesMoved:withEvent:, touchesEnded:withEvent:, touchesCancelled:withEvent:当发生触碰事件的时候可以使用这些方法
(15)gestureRecognizerShouldBegin:发生触碰时间或者其他的手势时间的时候可以使用这个方法
5.UIview的方法大全：
