The array is empty at that point. A good idea is, add some lines of code like this:

NSLog(@"\n\n here, there are this many items: %d \n\n", [yourArrayName count]);

put that line in everywhere possible, add it in at least ten places.

Open your console ("Run" menu in XCode).

You'll soon figure out what is going wrong! hope it helps.
