i am getting these errors when i try to compile on iOS:
on ios: FBLinkShareParams *dialogParams = [[[FBLinkShareParams alloc] init] autorelease]; /Users/Daniel/Repositories/Unity5/FacebookTest/Assets/Facebook/Editor/iOS/FbUnityInterface.mm:561:73: 'autorelease' is unavailable: not available in automatic reference counting mode
/Users/Daniel/Repositories/Unity5/FacebookTest/Assets/Facebook/Editor/iOS/FbUnityInterface.mm:662:15: No known class method for selector 'publishInstall:withHandler:'
now these don't seem to be that much of a problem, so is there any Facebook developer here who can give as a fast workaround this? How is responsible for this at Facebook, why can't we contact them directly?
Put -fno-objc-arc in the compile flags of the FbUnityInterface.mm , and it will work
Following user2018862's advice, this worked for me (setting the -fno-objc-arc flag for FbUnityInterface.mm), where FbUnityInterface.mm is found under the "Compiled Sources" section of the "Build Phases" pane.
