Now i want to integrate that in my project so i am referencing the project into my app but it leads to a crash and console shows exception that unknown CalendarAppDelegate.

What should I do?

Got the answer. Guys please help. This time though i got the answer on my own. Needed to import the xcodeproject file and put "other linker flags" in project settings as ObjC and it is working!!..

Thanks anyways.
