子视图不响应父视图的手势

1.遵守协议
UIGestureRecognizerDelegate

2.父视图的手势设置代理
UITapGestureRecognizer *fathertap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(fateherviewtap)];
fathertap.delegate=self;
[self addGestureRecognizer:fathertap ];

3执行代理方法

• (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;
  }
