将Facebook与iOS集成

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)

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.

Answer 2

使用Account.framework，您还必须添加Social.framework和AdSupport.framework。

Answer 3

如果您从另一个项目中拖放Adsuport，Accounts或Social库，并选择“将项目复制到目标组的文件夹”，AdSuport和社交目录将创建到您的应用程序源文件夹中，您将收到此链接器错误，删除目录并添加库从项目的Buld Phases - > Link Binary，您可能还需要添加libsqlite3.dylib

Answer 4

I think the Accounts.framework needs to be required. But it is only implemented in iOS 5 and later see developer reference for more information.

Answer 5

Solved this by upgrading to xcode 4.5.1 and then adding the social and adsupport framework and also the -lsqlitee3 or so as stated. I did add lsqlite3 before but it said multiple values on top so i just took the unnecessary for base sdk comments out and it worked.
