However this wont work. The Run Log keeps saying "attempt to insert
nil". But when I try nslog as above, it tells me the number.
Try replacing your NSLog call with this:
NSLog(@"track: %@\n", trackDictionary);
Most obviously, trackDictionary is nil. So you might want to check your
tracksDict dictionary, especially the way you saved the
key-value-pairs.
