You can use scrollRectToVisible to always have it appear in the same spot. Let’s say you have a UIScrollView where the frame size is (100,100). And you have a content size of (100,200). If you wanted that to appear at the top, you would call:

[self.myScrollView scrollRectToVisible:CGRectMake(0, 0, 100, 100) animated:NO];

if you wanted to center the content you would do this:

[self.myScrollView scrollRectToVisible:CGRectMake(0, 50, 100, 100) animated:NO];

if this is not working for you, then your scrollview is not setup properly and you’d need to provide more details on how you set it up.
