I\'m using the ARCified version of KeychainItemWrapper available at github, and I can\'t get it to store both email and password.
KeychainItemWrapper *keycha
I know its an old question, but that was happening to me and the above answers did not fix my problem. In my case I was accessing the keychain when the phone was locked. Finally I got to solve it by using this just after init the keychain.
keychainWrapper.setObject(kSecAttrAccessibleAlways, forKey: kSecAttrAccessible)
It seems that keychain does not let you access it unless your phone is unlocked, by default.

Well, I just found the answer following the advice on that page iOS KeychainItemWrapper not updating, which is to add
[keychainWrapper setObject:@"Myappstring" forKey: (id)kSecAttrService];
