Ok, I recently added Game center to my app, just for high scores and all, but when I compile it, it gives me 96 errors... All involving Game center, I'm going to show the main errors and see if any of you know how to fix it... Most of them are one error repeating multiple times, so this should only really be 5 or 6 errors.
Unknown type name
Cannot find protocol decleration for: (multiple in this category)
Expected a type
Use of undeclared identifier
That's it, I did a search on Google, but I didn't know what to do... I wanted to hear it from people who use MMF2.
