Scroll to bottom of UITextView erratic in iOS 7

Question

The following code will work fine in iOS < 7.0. In iOS 7 the scrolling will be choppy and erratic while the UITextView is updating. I\'m not sure if this is a bug in iO

Answer 1

There are two problems in iOS 7 that could explain your problem:

• The contentOffset is not always up to date in iOS 7.
• scrollRangeToVisible: will not scroll to an empty line at the end of the text view.

The solution could be:

-(void)scrollOutputToBottom {
    CGRect caretRect = [textView caretRectForPosition:textView.endOfDocument];
    [textView scrollRectToVisible:caretRect animated:NO];
}
