I don't want to use NSUserDefaults as I have been told it's not a good way to save a username and password.
So I was going to use a Keychain, but I have never used them before. Can some one please just a give a quick example of one or point me in the direction of an example ? Thanks.
I Use the open source SSKeychain wrapper around the the C api used by the keychain.
It's convenient, easy to use, and works on Mac OS and iOS.
This is the best I have found till date... It five a very simple implementation of saving passwords and username to keychain. Please remember to include security framework in your project.

Keep in mind that this doen't work on simulator.
