uitextfield - In iOS7 Text Magnifier isn't working app wide

Question

I have a came across a rather annoying bug in one of my apps. In iOS7 when I hold down on a UITextView or UITextField to bring up the Magnifying Glass, nothing shows up in the magnified area. This problem is app wide and the only element that ever shows up in the circle area is the keyboard itself (when I drag my finger down to the top of it).

I have tried everything from View Controllers with only a single UITextView to UIWebView and the problem is app wide.

The magnifying glass works as expected on iOS6 devices, and the iOS7 simulator. But not on any of the devices I have tested it with running iOS7.

Any help would be greatly appreciated.

I fixed this by setting the windowLevel of my main window to a float value of 1.2 in appDelegate:

self.window.windowLevel = 1.2;

This is a sort of hack for iOS7 to raise the default level of your main window which is UIWindowLevelNormal (1.0) to 1.2
