Is there a better way than this to save data to keychain using SSKeychain pod or is this way ok?

    if (self.accessToken.length == 0){
        NSLog(@"Access token needs to be retrieved from memory");
        NSError *error = nil;
        self.accessToken = [SSKeychain passwordForService:@"Internet password" account:@"Instagram" error:&error];
        NSLog(@"Checking for errors whilst retrieving password");
        if ([error code] == errSecItemNotFound) {
            NSLog(@"Password not found");
            [SimpleAuth authorize:@"instagram" completion:^(NSDictionary *responseObject, NSError *error) {
                NSLog(@"Response: %@", responseObject);
                self.accessToken = responseObject[@"credentials"][@"token"];
                [SSKeychain setPassword:self.accessToken forService:@"Internet password" account:@"Instagram"];
                NSLog(@"Data saved to keychain");
                [self retrieveTag];
            }];
        } else if (error != nil) {
            NSLog(@"Some other error occurred: %@", [error localizedDescription]);
        } else {
            NSLog(@"Access token retrieved from memory");
            [self retrieveTag];
        }
    } else {
        NSLog(@"Access token already retrieved");
        [self retrieveTag];
    }
