Hello,
I just put together this small but very helpful class for App Store links. In my opinion, Apple doesn't make it easy enough to link to pages on the App Store from your app. After digging around online and experimenting, I have some working methods that I wanted to share. Here are some examples of using the class. There are more details on the wiki page. Enjoy!
