CoreResource Fails to Build for iOS 4.0+

Reported by John Wang | August 17th, 2010 @ 09:25 PM

When building the examples and CoreResource in general, it fails to build on iOS 4.0+

Build Result messages: "OBJC_CLASS$_CoreJSONDeserializer", referenced from:

  objc-class-ref-to-CoreJSONDeserializer in CoreResource.o

"OBJC_CLASS$_CoreJSONDeserializer", referenced from:

  objc-class-ref-to-CoreJSONDeserializer in CoreResource.o

"_descendingSort", referenced from:

  _descendingSort$non_lazy_ptr in NSMutableArray+Core.o
 (maybe you meant: _descendingSort$non_lazy_ptr)

"_ascendingSort", referenced from:

  _ascendingSort$non_lazy_ptr in NSMutableArray+Core.o
 (maybe you meant: _ascendingSort$non_lazy_ptr)

ld: symbol(s) not found

Lines causing the problem seems to be:
- (void) sortUsingKey:(id)key ascending:(BOOL)ascending {

[self sortUsingFunction:ascending ? ascendingSort : descendingSort context:key];


And also a failure to include CoreDeserializer.h and .m into examples.

    Regretfully, there hasn't been much. I had a couple of short bursts, but kept getting pulled back into unrelated client work.

    I'm nearing the end of my 4-month project... I'm hoping to get back to CR in the next few weeks, as it's necessary for a couple of apps I'm working on. I've said that before, though... :-)

    It looks like the Twitter example failed to build in iOS 4.2 because NSArray+Core was not included in the project. The Lighthouse example built and ran fine for me though. To fix this problem with the Twitter example, just drag and drop NSArray+Core.(h|m) into the appropriate spot in the source Group Tree in the Twitter example proj (You don't need to copy in place when it prompts you but make sure it is added to the Twitter target).

    Note: You could usually just add NSArray+Core.(h|m) to the proj via the standard 'Add Existing Files' approach but for some reason, the Twitter example proj already thought they were included. Hence, the drag/drop approach from the other proj.
