Having tested our edge animate generated UI in an embedded UIWebView many of the animations get stuck/don't complete or repeat strangely in IOS7.
Also the animations are generally stuttering/low frame rate whilst in IOS6 these were fine.
This was tested with an iPad 3. The animations we use are svg timeline animations. They also work fine in the IOS7 iPad simulator, this only occurs on hardware.
Any ideas/ anyone aware of this issue?
You might want to try posting on the Apple Developer forums since discussions around iOS7 are under NDA per your developer agreement. I suggest searching there for assistance on what might be changing with UIWebView.
