A very hacky way to enable UITextView to scroll to the cursor when typing. I believe I got this from someone on SO but I can't find the original source anymore

gistfile1.m

- (void)textViewDidChange:(UITextView *)textView {
    [self _showTextViewCaretPosition:textView];
}

- (void)textViewDidChangeSelection:(UITextView *)textView {
    [self _showTextViewCaretPosition:textView];
}


- (void)_showTextViewCaretPosition:(UITextView *)textView {
    CGRect caretRect = [textView caretRectForPosition:self.lyricsText.selectedTextRange.end];
    [textView scrollRectToVisible:caretRect animated:NO];
}
