MGSplitViewController is a UISplitViewController replacement class built by Matt Gemmell. I’ve never really had much use for it until today. When i downloaded it, I saw that the demo (and the actual class) were not compatible with iOS 6. After reading through the issues, and playing around with the class to try to get it working for my own needs, I was able to address the issues that prevented this app from working in iOS 6. I’ve pushed my changes into my own fork of the project, which can be found on here, on Github. I’ve sent Mark a pull-request, so that he can merge it onto the project’s main master branch.
Kudos to Matt Gemmell for creating the original class.
