I'm trying to get my scroll view, which contains a UIImageView, to just pan around it. I was having issues, so I set up to KVO the contentSize property.
I'm getting called back constantly, every 500 ms.
The call stack shows Core Animation causing it, but I have no on-going animations, and none that run every 500 ms. My log is filled with this. Any ideas?
