Create the password pin view.
The source files you added from the SMP/SUP101 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.
