When I login to my app with my email and password I am getting a response successfully at that time, to save my userid into nsuserdefaults, how can I do that?

当我用我的电子邮件和密码登录到我的应用程序时，我得到了一个成功的响应，为了将我的userid保存到nsuserdefaults，我怎么做呢?

Here is my code:

这是我的代码:

-(void)signInMethod
{
    NSString *accessKey = @"akjsda9s8dadandl4";
    NSData *returnData;
    returnData=[[WebServices alloc]loginTest:emailTxtFld.text andPassword:pswdTxtFld.text andSESSION_ACCESS_KEY:accessKey];
    if (returnData.length>0)
    {
        NSError *error;
        NSDictionary *res=[NSJSONSerialization JSONObjectWithData:returnData options:kNilOptions error:&error];
        NSLog(@"SignIn response is %@",res);
        NSString *msg = [res valueForKey:@"userid"];
        NSLog(@"%@",msg);
    }
}

From the above code WebServices is my Service Class. How can I save that userid?
