It's hard to tell without seeing your code, but two possibilities spring to mind:

1. You're trying to set the badge value from a thread that is not the main thread. Try wrapping your badge value setting code in a dispatch_async to the main queue:

   dispatch_async(dispatch_get_main_queue(), ^
   {
       // set badge number    
   });
   

2. The item that you're setting the badgeValue on is nil. Try adding a breakpoint or some NSLog statements to the line where you add the badge number, and check the value of some of the objects isn't nil.
