If you touch and hold on a UITextField or UITextView, a magnifying glass appears above it, with the text, but magnified. I'm trying to find it in the view hierarchy of my app. But I can't. What is it, and where is it located? Presumably a private class somewhere -- I know I can't mess with it in an app store submission -- but it should still have a class name and exist somewhere in the hierarchy. But what and where?
