iOS：ScrollView的SetContentOffset不起作用

Question

I have 3 Scrollviews and they should scroll synchron with the other...

But this code doesn't work:

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
[rowIdCellScrollView setContentOffset:CGPointMake(0, contentScrollView.contentOffset.y)];
[headerScrollView setContentOffset:CGPointMake(contentScrollView.contentOffset.x, 0)];
}

Answer 1

Do you have UIScrollViewDelegate? And set delagate:

rowIdCellScrollView.delegate = self;

And does this scrollViewDidScroll even call?

Answer 2

我找到了解决方案，问题是，我在layoutsubviews中初始化了组件...
