iOS KeychainItemWrapper not updating

Question

I just found an interesting problem with my app. In the app I am saving the user\'s user name and password to the keychain.

keychainWrapper = [[KeychainItemW         


        

Answer 1

When you include

keychainWrapper = [[KeychainItemWrapper alloc] initWithIdentifier:@"MyLoginPassword" accessGroup:nil];

[keychainWrapper setObject:usernameField.text forKey:(id)kSecAttrAccount];
[keychainWrapper setObject:passwordField.text forKey:(id)kSecValueData];

you also had to include

[keychainWrapper setObject:@"Myappstring" forKey: (id)kSecAttrService];

Or I get a "SIGABRT" error. (Myappstring) is a string defining your application.

Maybe I'm missing something, this should be done at least once.
