Create the password pin view.
The source files you added from the SMP101 iOS Object API example project contain the PasswordPinViewController.h, PasswordPinViewController.m, and PasswordPinViewController.xib files that create the password pin view. This file also supports creating a new pin. To create these files manually in Xcode, you would create a new file using the UIViewController subclass template, then indicate it is a subclass of UIViewController. Select With XIB for user interface.
Although the provided XIB file is already configured, you can walk through the steps to see how to create the interface.
