- 响应者对象:iOS中继承了UIResponder的对象才可以接收并处理事件,这些对象称之为响应者对象
触摸事件
- 一根或者多根手指开始触摸view,系统会自动调用view的下面方法
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
- 一根或者多根手指在view上移动,系统会自动调用view的下面方法(随着手指的移动,会持续调用该方法)
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
- 一根或者多根手指离开view,系统会自动调用view的下面方法
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
- 触摸结束前,某个系统事件(例如电话呼入)会打断触摸过程,系统会自动调用view的下面方法
- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event
- touches中存放的都是UITouch对象
加速计事件
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event;
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event;
