uiscrollview缩放和UIButton冲突

[独一无二的skye]

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
UIView *view = [touch view];

if ([view isKindOfClass:[LocationButton class]]) {
return NO;
}
return YES;
}

不好使，为什么？
scrollview 上 有图片和好多UIButton ,放大scrollview 碰到Button ,Button高亮同时scrollview不放大。这个冲突怎么改？
