How do I use Apple Keychain?

Question

I am using trying to use scifihifi-iphone (from Github) to store and retrieve usernames and passwords. However, when I add the class SFHFKeychainUtils I get the following errors:

  "_kSecAttrAccount", referenced from:
      _kSecAttrAccount$non_lazy_ptr in SFHFKeychainUtils.o
  "_SecItemDelete", referenced from:
      +[SFHFKeychainUtils deleteItemForUsername:andServiceName:error:] in SFHFKeychainUtils.o
  "_kSecReturnAttributes", referenced from:
      _kSecReturnAttributes$non_lazy_ptr in SFHFKeychainUtils.o
  "_kSecClass", referenced from:
      _kSecClass$non_lazy_ptr in SFHFKeychainUtils.o
  "_kSecClassGenericPassword", referenced from:
      _kSecClassGenericPassword$non_lazy_ptr in SFHFKeychainUtils.o
  "_SecItemAdd", referenced from:
      +[SFHFKeychainUtils storeUsername:andPassword:forServiceName:updateExisting:error:] in SFHFKeychainUtils.o
  "_kSecAttrLabel", referenced from:
      _kSecAttrLabel$non_lazy_ptr in SFHFKeychainUtils.o
  "_SecItemUpdate", referenced from:
      +[SFHFKeychainUtils storeUsername:andPassword:forServiceName:updateExisting:error:] in SFHFKeychainUtils.o
  "_kSecAttrService", referenced from:
      _kSecAttrService$non_lazy_ptr in SFHFKeychainUtils.o
  "_kSecReturnData", referenced from:
      _kSecReturnData$non_lazy_ptr in SFHFKeychainUtils.o
  "_SecItemCopyMatching", referenced from:
      +[SFHFKeychainUtils getPasswordForUsername:andServiceName:error:] in SFHFKeychainUtils.o
      +[SFHFKeychainUtils getPasswordForUsername:andServiceName:error:] in SFHFKeychainUtils.o
  "_kSecValueData", referenced from:
      _kSecValueData$non_lazy_ptr in SFHFKeychainUtils.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

What am I leaving out? When I click the errors, it doesn't take me to any place in the code.

It looks like a linker error. Is this the first time your code has done anything with Keychain? — Matt Ball, Oct 12 '09 at 14:44

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 Frameworks and choose (or navigate) to Security.framework.

Thanks, that's great. I was looking for a framework called Keychain.framework which obviously doesn't exist. – Jason Oct 12 '09 at 17:29

That solved my problem BUT I had to drag Security.framework into the project from Finder, adding it in the XCode 4.2 "link with libraries" section did not work (it didn't seem to find the framework it had added). – Kendall Helmstetter Gelner Nov 19 '11 at 02:55
