如何停止显示字符的UITextField Secure文本

Question

I've enabled Secure text for my UITextField. At runtime when I type some text in I initially see the character before it turns to a bullet point. Is there a way to stop it showing the characters and having it as a bullet point as I type.

Is there something I need to add to

-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string

Has anyone got an example?

Answer 1

I dont know its good practice or not but following trick did it for me

-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
    NSString *editedString = [textField.text stringByReplacingCharactersInRange:range withString:string];
    textField.text = editedString;
    return NO;
}

That is the default behaviour of the UITextField . So there's nothing much you can do about it. You can play with some kind of encryption on the coding side but on the view side, this behaviour will prevail.
