Currently, I test whether a UITextView is dirty or not by:

if ([self.textView.undoManager canUndo]) ...

Is this always correct? Or is there any isDirty-like method in UITextView?

    You can listen to lots of things with the UITextViewDelegate

    Check out the UITextViewDelegate documentation for comprehensive details

    - (void)textViewDidBeginEditing:(UITextView *)textView

    - (void)textViewDidEndEditing:(UITextView *)textView

    - (void)textViewDidChange:(UITextView *)textView

    There’s more to do with shouldBegin and shouldEnd editing, and also selection changes.

    Hope that helps out.
