1.0 iOS中的事件

概念：

在iOS中不是任何对象都能处理事件，只有继承了UIResponder的对象才能接收并处理事件。

成员：

UIApplication、UIViewController、UIView都继承自UIResponder，因此它们都是响应者对象，都能够接收并处理事件

UIResponder的内部方法：

1 //触摸事件  2 - (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(nullable UIEvent *)event;  3 - (void)touchesMoved:(NSSet<UITouch *> *)touches withEvent:(nullable UIEvent *)event;  4 - (void)touchesEnded:(NSSet<UITouch *> *)touches withEvent:(nullable UIEvent *)event;  5 - (void)touchesCancelled:(nullable NSSet<UITouch *> *)touches withEvent:(nullable UIEvent *)event;  6 - (void)touchesEstimatedPropertiesUpdated:(NSSet * _Nonnull)touches NS_AVAILABLE_IOS(9_1);

1 //加速计事件  2 - (void)motionBegan:(UIEventSubtype)motion withEvent:(nullable UIEvent *)event NS_AVAILABLE_IOS(3_0);  3 - (void)motionEnded:(UIEventSubtype)motion withEvent:(nullable UIEvent *)event NS_AVAILABLE_IOS(3_0);  4 - (void)motionCancelled:(UIEventSubtype)motion withEvent:(nullable UIEvent *)event NS_AVAILABLE_IOS(3_0);

//远程控制事件  - (void)remoteControlReceivedWithEvent:(nullable UIEvent *)event NS_AVAILABLE_IOS(4_0);
