1、添加 UITapGestureRecognizer
// double tap
UITapGestureRecognizer *doubleTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleTap:)];
doubleTapRecognizer.numberOfTapsRequired = 2;
doubleTapRecognizer.delaysTouchesBegan = YES;
[self.view addGestureRecognizer:doubleTapRecognizer];// single tap
UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tap:)];
// 双击手势确定监测失败才会触发单击手势的相应操作
[tapRecognizer requireGestureRecognizerToFail:doubleTapRecognizer];
[self.view addGestureRecognizer:tapRecognizer];// single tap
UILongPressGestureRecognizer *gesture = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPress:)];
gesture.minimumPressDuration = 1.5;
gesture.numberOfTouchesRequired = 1;
[self.view addGestureRecognizer:gesture];
2、实现相关触发事件
- (void)doubleTap:(UIGestureRecognizer *) gr {
NSLog(@"doubleTap");
}
- (void)tap:(UIGestureRecognizer *) gr {
NSLog(@"tap");
}
- (void)longPress:(UIGestureRecognizer *) gr {
NSLog(@"longPress");
}
