UITextfield totally secure without showing initial character for a while

I want to set uitextfield as total secure field. However, when user type one character, it is also shown on screen. I would like to hide the initial character also and when user type something (For eg. "A"), it show only secure text(. or *). How shall I do?

this is the best solution for achieving behaviour that you describe:

- (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;
}

don't forget to set correctly delegate to your UITextField:

self.myTextField.delegate = self;

Here is a proposal for a solution. Use a second text store for the unhidden text, while replacing the textfield's text from your code, after changing the second text store. Listen to textField:shouldChangeCharactersInRange:replacementString: as the text field's delegate, perform the changes mentioned, replace the characters with ● and return NO in the delegate method.

If you don't mind seeing dots instead asterisks, you can set the SecureTextEntry attribute to YES:

[yourUITextField setSecureTextEntry:YES];
