When test my app for the upcoming iOS7, I noticed that the scrolling to the active text field no longer works.
I tried just testing the supplied Example.xcodeproj to ensure it was not something funky I was doing.
The Example project worked fine when running in the iOS6 simulator. I can navigate to the all the fields back and forth, using the next and previous buttons. The view is scrolled and focused properly.
However, when I run this on the iOS7 simulator, I can navigate to the first few fields fine in the Example project. When I get to the "Your favorite food?" field, pressing the "Next" button, scrolls the view to the top - showing Username, Password, etc... but cursor is in "Your favorite movie?" field behind the keyboard. In my app, the same thing is occurring.
I believe the problem is in the scrollRectToVisible and the iOS7 keyboard. I know this is probably not a problem with this great control - but it will "break" the Example once iOS7 is released if there is not a fix with Apple or another workaround.
