单击手势与双击手势

    //单击手势UITapGestureRecognizer *tap1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapAction:)];//设置点击的次数tap1.numberOfTapsRequired = 1;//设置手指的个数tap1.numberOfTouchesRequired = 1;//将手势添加到视图上[self.view addGestureRecognizer:tap1];//双击手势UITapGestureRecognizer *tap2 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleAction:)];tap2.numberOfTapsRequired = 2;//添加手势[self.view addGestureRecognizer:tap2];//区别两个手势[tap1 requireGestureRecognizerToFail:tap2];
}//单击手势响应的事件
- (void)singleTapAction:(UITapGestureRecognizer *)tap {//关闭手势
//    tap.enabled = NO;//获取手势所在的视图UIView *view = tap.view;view.backgroundColor = [UIColor colorWithRed:arc4random_uniform(10)/10.0 green:arc4random_uniform(10)/10.0 blue:arc4random_uniform(10)/10.0 alpha:1];NSLog(@"singleTapAction");
}//双击手势响应的事件
- (void)doubleAction:(UITapGestureRecognizer *)tap {NSLog(@"doubleAction");
}

轻扫手势

- (void)_initSwipeGesture {UISwipeGestureRecognizer *swipeGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeAction:)];//设置轻扫的方向/*UISwipeGestureRecognizerDirectionRightUISwipeGestureRecognizerDirectionLeftUISwipeGestureRecognizerDirectionUpUISwipeGestureRecognizerDirectionDown*/swipeGesture.direction = UISwipeGestureRecognizerDirectionDown;[self.view addGestureRecognizer:swipeGesture];

}

平移手势

- (void)_initPanGesture {UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panAction:)];[self.view addGestureRecognizer:panGesture];
}- (void)panAction:(UIPanGestureRecognizer *)pan {//手指所在的坐标CGPoint point = [pan locationInView:self.view];_view.center = point;
}

长按手势

- (void)_initLongGesture {UILongPressGestureRecognizer *pressGesture = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(pressAction:)];//设置最短时间pressGesture.minimumPressDuration = 1;[self.view addGestureRecognizer:pressGesture];}- (void)pressAction:(UILongPressGestureRecognizer *)press {/*UIGestureRecognizerStateBegan   开始UIGestureRecognizerStateChanged    改变UIGestureRecognizerStateEnded   结束UIGestureRecognizerStateCancelled  取消*/if (press.state == UIGestureRecognizerStateBegan) {NSLog(@"pressAction");}
}

旋转手势

缩放手势

- (void)_initPinchGesture {UIImageView *imgView = [[UIImageView alloc] initWithFrame:[UIScreen mainScreen].bounds];imgView.userInteractionEnabled = YES;imgView.image = [UIImage imageNamed:@"5.jpeg"];[self.view addSubview:imgView];UIPinchGestureRecognizer *pinchGesture = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(pinchAction:)];[imgView addGestureRecognizer:pinchGesture];}- (void)pinchAction:(UIPinchGestureRecognizer *)pinch {//    pinch.scale;    //缩放比NSLog(@"pinchAction：%f",pinch.scale);UIImageView *imgView = (UIImageView *)pinch.view;if (pinch.state == UIGestureRecognizerStateChanged) {imgView.transform = CGAffineTransformMakeScale(pinch.scale, pinch.scale);}else if (pinch.state == UIGestureRecognizerStateEnded || pinch.state == UIGestureRecognizerStateCancelled) {[UIView animateWithDuration:0.3 animations:^{imgView.transform = CGAffineTransformIdentity;}];}}
