Question

On my app I need to do this: when a character is typed on TextView to be saved on a NSString and after that to be replace with ‘*’. I tried this :

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
    NSLog(@"typing...");
    text=@"*";
    passwordText=textView.text;
    NSLog(@"password %@",passwordText);

    NSString* nextText = [textView.text stringByReplacingCharactersInRange:range withString:text];
    textView.text=nextText;
    NSLog(@"next %@",nextText);
    NSLog(@"textview.text %@",textView.text);

    return YES;
}

where passwordText is the NSString in which I want to save the text introduce from keyboard on UITextView.

The result is this : http://i54.tinypic.com/2cx9ueo.png (here I introduced ‘we’ and I see this :’*w*e’. Can anyone help me to solve this?

I mention that I must do this using UITextView, and not UITextField.

Answer 1

I can tell you why you get character along with the *, though i am not sure whether your approach is worth to go through this.

make your return statement as NO, this will discard the new key pressed. The YES is currently placing that character next to your programmatic ‘*’.
