UITextField hide all characters

Question

Our customers want a Textfield for a Password which is not showing any character while typing.

Is there any Setting in iOS to activate this behaviour or is it possible to hide also the last typed character using the secureTextEntry property on a UITextField?

Answer 1

You can set your view controller as delegate for your text field, and add the following method, this will not allow the text field to show that last character:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
    if (textField == self.pinTextField) {
        NSString *currentText = textField.text;
        NSString *newText = [currentText stringByReplacingCharactersInRange:range withString:string];
        textField.text = newText;
        return NO;
    }
    return YES;
}
