UIkit框架之Uivew
1.繼承鏈：UIresponder：NSObjecthtml
2.經過使用 addGestureRecognizer:方法能夠爲視圖添加手勢spring
3.下面的屬性均可以用來用於動畫api
-
@property transformiview
4.子視圖通常用來進行覆蓋的方法：
(1)initWithFrame:通常用來初始化一個UI控件，位置和大小
(2)initWithCoder:使用這個方法來載入你的nib file文件到interface builder中
(3)layerClass:不知道怎麼翻譯 Implement this method only if you want your view to use a different Core Animation layer for its backing store.
(4)drawRect:通常用來繪製你的自定義視圖內容
(5)drawRect:forViewPrintFormatter:當你想在你的自定義視圖中定義不一樣的視圖內容能夠重載這個方法
(6)requiresConstraintBasedLayout:若是你想要正確的約束你的視圖可使用這個方法
(7)updateConstraints:若是你的視圖和你的子視圖要建立有一個自定義約束可使用這個方法，應該是用來更新約束的把
(8)alignmentRectForFrame:, frameForAlignmentRect:實現讓你的視圖如何和其餘視圖對齊
(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:使用這個方法來使你的視圖更加精確的佈局而不使用那些約束
(11)didAddSubview:, willRemoveSubview:能夠用來更加或者刪除一些視圖
(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:當發生觸碰事件的時候可使用這些方法
(15)gestureRecognizerShouldBegin:發生觸碰時間或者其餘的手勢時間的時候可使用這個方法
