当我使用我的电子邮件和密码登录我的应用程序时,我当时成功收到回复,要将我的用户ID保存到nsuserdefaults
,我该怎么做?
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);
}
}
从上面的代码WebServices
是我的服务类。如何保存该用户ID?

NSString *msg = [res valueForKey:@"userid"];
[[NSUserDefaults standardUserDefaults] setObject:msg forKey:@"userid"];
[[NSUserDefaults standardUserDefaults] synchronize];
NSLog(@"%@",msg);

要重新使用
NSString *UDID = [[NSUserDefaults standardUserDefaults] objectForKey:@"userid"];
