Question

In Apple’s apps I notice the scrolling is perfect. Everything moves nicely and when you stop, it stops. You can have a huge image and move directly to any spot and it stays there.

I’d like to provide the same UE, but for my apps, if the content exceeds the size of the scroll view (as it should – otherwise what’s the point in having a scroll view?) the scroll view never stays put, you have to drag to see content on the edges, then it bounces back and hides it again. Very annoying, especially if there is active content like a button there.

I’m not an iOS expert, e.g. I just found out recently about how critical viewWillAppear is w.r.t. UIScrollView. Is there a concise reference somewhere on how to get perfect rock solid scrolling? (i.e. not Apple’s Dev docs!)

Thanks for reading,

Answer 1

Are you setting the contentSize property on the UIScrollView?

scrollView.contentSize = CGSizeMake(2000, 2000);
