（3）总结

——先根据所需创建不同类型的手势识别，比如：

UITapGestureRecognizer
UISwipeGestureRecognizer
UIPinchGestureRecognizer
UIRotateGestureRecognizer
UIPanGestureRecognizer

——然后把这些手势对象利用addGestureRecognizer方法添加到需要的那个对象中去，如：

[self.imgView addGestureRecognizer:swipe];

UIPinchGestureRecognizer *pinch=[[UIPinchGestureRecognizer alloc]initWithTarget:self action:@selector(pinchView:)];

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{
    return YES;
}
