I have a scroll view that has a variable number of UIImageView subviews. I subclassed UIScrollView because I want to be able to move and resize the images with gestures, and do some other custom behavior. As soon as I switch the scroll view to my subclass in the nib file, some strange things happen: the scroll view will expand vertically and cover other views when scrolled upward, and the bottom edge stops short of the full screen and leaves a big gap...but when I change it back to a regular UIScrollView, it's fine. I don't override anything in my subclass or set anything in the nib that I believe could cause this...all I do is override the addSubview method, and add gesture recognizers to subviews as they are added to my scroll view, and of course have methods to handle those gesture recognizers. Any ideas as to what I'm doing wrong?
Thanks in advance!
Got it! The problem, it seems, was that I had a method called handlePan...by doing this I had inadvertently overridden an identically-named method of UIScrollView. So, my handlePan (which I had intended only to handle the pans for my subviews) was instead handling all pans, including the scrollview's built-in one, and causing the weird scrolling. Whoops! Problem solved.
