一. 手势类常用的代理方法，解决手势和点击cell的冲突

手势是OC中的类，那么手势类也是有协议的，UIGestureRecognizerDelegate，手势常用的代理方法：

1.是否允许同时支持多个手势，默认只支持一个手势，要调用此方法注意设置代理
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

2.是否允许开始触发手势
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
    return NO;
}

3.是否允许接收手机的触摸(可以控制触摸的范围)
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
    //获取当前的触摸点
    CGPoint currentP = [touch locationInView:self.imageView];
      在图片的左半区域可以接受触摸
    if (currentP.x < self.imageView.bounds.size.width * 0.5) {
        return YES;
    }else {
        return NO;
    }
}

例如：- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {

  　　// 输出点击的view的类名 //NSLog(@"%@", NSStringFromClass([touch.view class]));

       // 若为UITableViewCellContentView（即点击了tableViewCell），则不截获Touch事件

      if ([NSStringFromClass([touch.view class]) isEqualToString:@"UITableViewCellContentView"])

     { return NO; }

return YES; 

}
