Integrating Facebook with iOS

Question

I get all these errors and about 18 more when i try to integrate facebook to my application.

Undefined symbols for architecture i386:
"_ACAccountTypeIdentifierFacebook", referenced from:
  +[FBSession renewSystemAuthorization] in FacebookSDK(FBSession.o)
"_ACFacebookAppIdKey", referenced from:
  -[FBSession authorizeUsingSystemAccountStore:accountType:permissions:defaultAudience:isReauthorize:] in FacebookSDK(FBSession.o)
"_ACFacebookAudienceEveryone", referenced from:

"_ACFacebookAudienceFriends", referenced from:

"_ACFacebookAudienceOnlyMe", referenced from:

Im using the latest facebook instructions on how to add facebook to my page but i am working with iOS 4.3 and above. SO it needs to cater to 4.3. I have set Accounts.framework to optional. Any one knows what these erros mean? Ive also tried adding any other implementation files that are not linked.

The errors are generated everytime i access FBSession or FBConnect etc.

Answer 1

For the record: we expect you to use XCode 4.5 for developing with the Facebook SDK 3.1 as described here

Account.framework, Social.framework and AdSupport.framework are all required (as described here) but use the 'optional' flag if you want to build for older iOS versions too.

Good luck.
