Implementing an In-App App Store

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.

Customizing UILabel Hyperlinks

For the ProductLayer prod.ly app I wanted to show a timeline of user opines. Opines are – in spirit – similar to tweets and as such can also contain hyperlinks. In this post I am discussing how to customize hyperlink drawing for UILabels. In a second article on this subject I will then show how to implement tappable hyperlinks for UILabel as well.

Years of Barcodes

My last 15 months had a common theme: barcodes. At this point all my research, coding and writing is finally allowed to move into the public sphere, plainly visible for all who care. And incredibly interesting for those who don’t just yet.
