You can read this sample code on GitHub.

It implements the UIKeyInput protocol to produce a custom input view.

Do you mean u want the digits to be asterisk?

if yes just go on to your xib file click the textfield

and go to inspector attributes and check the secure button.

if it is ok, thet there will be spaces to separate numbers:

[text addTarget:self action:@selector(textFieldEditing:) forControlEvents:UIControlEventEditingChanged];

- (IBAction)textFieldEditing:(id)sender {
    //separate string of your TextField text and add spaces where you whant
    [sender setText:(NSString *)]
}

you can try adding an observer to UITextFieldTextDidChangeNotification; every time that notification is fired, you can re-format the input.
