Aha, NSUserDefaults seems to work, and is simple to use, but isn't secure in the slightest:

password is the IBOutlet for the UITextField.

- (void)viewWillAppear:(BOOL)animated
{
    NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
    NSString *pword = [prefs objectForKey:@"password"];
    password.text = uname;
}

- (void)viewWillDisappear:(BOOL)animated{
    NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
    [prefs setObject:password.text forKey:@"password"];
}

The password is stored in plain-text in a plist, so it would be quite easy for someone else to access.. but this is useful for storing non-sensitive settings.

I ended up using this to store the username field, and stored the password using the SFHFKeychainUtils keychain code from August's answer.
