Large amount of errors occurring when building my project that includes AFNetworking

/JSONKit.m:931:17: Direct access to objective-c's isa is deprecated in favor of object_setClass() and object_getClass()

Have you used the -v to get more information? – Toon Krijthe Mar 26 '13 at 08:03 — Toon Krijthe, Mar 26 '13 at 08:03

You're missing the required frameworks. Import SystemConfiguration and MobileCoreservices/CoreServices for iOS or OS X respectively.

After that you may want to see my answer here to fix the compiler warnings.
