子視圖不繼承父視圖的手勢

1.添加代理

UIGestureRecognizerDelegate

2.加手勢方法

[self.backgroundView addSubview:self.commentView];

   UITapGestureRecognizer * tap=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(hiddenTap:)];

    tap.numberOfTapsRequired=1;

    tap.numberOfTouchesRequired=1;

    tap.delegate=self;

    [self.backgroundView addGestureRecognizer:tap];

3.代理方法的具體操作

#pragma mark-UIGestureRecognizerDelegate 讓評論時的評論區域不受父視圖點擊手勢的影響

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

    if ([touch.view isDescendantOfView:self.commentView]) {//

        return NO;

    }

    return YES;

}
