If you have an app like prod.ly, which shows a timeline of user’s messages you probably want interactive hyperlinks. In two previous posts I showed how I am customizing UILabel to customize hyperlinks drawing, as well as how to make them react to touches. For most links a UIWebView will do to show the content.
But not for content that people can purchase and/or download from iTunes or the Apple App Store. For this, there is SKStoreProductViewController. This post shows how to implement it.
