Help needed using Apple Keychain.

Question

I am using trying to utilize some code found here to store and retrieve username and password. However, when I add the class (SFHFKeychainUtils) I get the following errors:

  "_kSecAttrAccount", referenced from:
      _kSecAttrAccount$non_lazy_ptr in SFHFKeychainUtils.o
  "_SecItemDelete", referenced from:
      +[SFHFKeychainUtils deleteItemForUsername:andServiceName:error:] in SFHFKeychainUtils.o

  "_kSecValueData", referenced from:
      _kSecValueData$non_lazy_ptr in SFHFKeychainUtils.o
ld: symbol(s) not found

Any ideas on what I'm leaving out? When I click the errors, it doesn't take me to any place in the code?

Answer 1

Add Security.framework. Then rebuild. Sometimes I find I have to build clean and then rebuild.

To add this, right click on your target in Xcode, then Add->Existing Framworks and choose (or navigate) to Security.framework.

Answer 2

Thanks a lot. Google Gdata need this framework
