iOS手势操作

iOS手势操作

1:继承<UIGestureRecognizerDelegate> 委托

2:设置委托

UIPanGestureRecognizer *panRcognize=[[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePan:)];
panRcognize.delegate=self;
[panRcognize setEnabled:YES];
[panRcognize delaysTouchesEnded];
[panRcognize cancelsTouchesInView];

[self.view addGestureRecognizer:panRcognize];

3:监控事件

#pragma UIGestureRecognizer Handles
- (void)handlePan:(UIPanGestureRecognizer *)recognizer {
    
    //获取的是x y 的增量
    NSLog(@"--移动的手势----- x:%f,y:%f",[recognizer translationInView:self.view].x,
          [recognizer translationInView:self.view].y);
    //获取的是x y 的位置   
    NSLog(@"--移动的手势－位置----- x:%f,y:%f",[recognizer locationInView:self.view].x,
          [recognizer locationInView:self.view].y);
}
