UIScrollView没有滚动另一个子视图的内容

Question

Hi everyone. I dragged a UIScrollView to my storyboard, then I added a UIView on top of that UIScrollView . This UIView loads another subview dynamically depending on what the server throws to this app.

The problem is the UIScrollView is not scrolling the content, even though I made the loaded UIView bigger than the UIScrollView . I'm not invoking [myScroller addSubView:myUiView] . Am I doing it right? Thanks in advance!

Answer 1

您必须设置滚动视图的内容大小。

Answer 2

Add this in your view controller.

- (void) viewDidLayoutSubviews
{
    [super viewDidLayoutSubviews];

    myScroller.contentSize = CGSizeMake(CGRectGetMaxX(myUiView.frame), CGRectGetMaxY(myUiView.frame));
}

Answer 3

For every time you change the content try calling

//removeFromSuperview the UIView was set as content view
self.myScroller.contentSize = self.myUiView.frame.size;
[myScroller addSubView:myUiView];

Don't forget to link both views on Interface Builder

PS: In this apporach the subView must not be inside the scrollView on IB
