touches,motion触摸事件响应

//触摸事件响应需要重写方法

 1 // 触摸时触发该方法(消息发送)
 - (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
     UITouch *touch = [touches anyObject];
     CGPoint point = [touch locationInView:self.rootView.touchView];//locationInView:得到当前点击下在指定视图中位置的坐标
     NSLog(@"触摸开始:%.2f,%.2f",point.x,point.y);
 }
 //但触摸移动时触发该事件
 - (void)touchesMoved:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{

     UITouch *touch = [touches anyObject];
     CGPoint point1 = [touch locationInView:self.rootView.touchView];
     CGPoint point2 = [touch previousLocationInView:self.rootView.touchView];//previouslocationInView:得到当前点的前一个点在指定视图中位置的坐标
 }
 // 触摸结束时触发该方法(消息发送)
 - (void)touchesEnded:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
     NSLog(@"触摸结束");
 }
 //发生其他情况,如来电话或意外退出时,执行该方法
 - (void)touchesCancelled:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{

 }

//手机摇一摇实现要重写方法

 1 //开始时调用
 - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event{
     NSLog(@"摇一摇开始");
 }
 //结束时调用
 - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event{
     NSLog(@"摇一摇结束");
 }
 //意外情况调用
 - (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event{
     NSLog(@"意外退出");
 }
