It seems to be some issue with ARC. Have you changed any settings in my example project?

@vinzenzweber I didn't change any setting in the example Project. I am using XCode 4.4.1 FYI.

But I understand that the example project works on XCode 4.3.1

Yes, It was working on iOS 5 and XCode 4.3 but when I have updated my iOS to 6th version and XCode also, then the above issue has appeared. Please let me know how to resolve it.
