Question

I want to remove the linefeed that was entered in by the return key. But when I do the following it remove the last character from the text. Why?

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text;
{
    NSLog(@"%d  %d  %@ %@",range.location,range.length, text, [textView text]);

    if ( [text isEqualToString:@"\n"] ) {

        NSString *s = [textView text];
        s = [s substringToIndex:[s length] - 1]; // <------------

        [tvText setText:[NSString stringWithFormat:@"%@\n>>",s]];
    }
    return YES;
}

---

I want the result to look like:

>>name
>>yoda
>>                <---- cursor is moved to the right of ">>"

I think you can do something like this,

    - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text;
{
    NSLog(@"%d  %d  %@ %@",range.location,range.length, text, [textView text]);

    if ( [text isEqualToString:@"\n"] ) {

        [tvText setText:[NSString stringWithFormat:@"%@\n>>",tvText.text]];
        return NO;
    }
    return YES;
}
