The UIAlertView class is intended to be used as-is and does not support subclassing. The view hierarchy for this class is private and must not be modified.
However, there are few important guidelines to keep in mind as you design your application:
You must deliver a digital good or service within your application. Do not use In-App Purchase to sell real-world goods and services.
You may not offer items that represent intermediary currency because it is important that users know the specific good or service they are buying.
Items you offer for purchase may not contain, or relate to, pornography, hate speech, defamation, or gambling (simulated gambling is acceptable).
