NSUserDefault 保存对象，登录问题？

Question

登录的时候我用userdefaults保存的user_id，但App关闭后台，在开启这个user_id就没了，我同样保存的telephone就在

LoginViewController.m

// NSUserDefault
            NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
            [defaults setObject:self.phoneString forKey:@"telephone"];
            [defaults          [defaults setObject:self.useridString forKey:@"user_id"];
            [defaults setValue:self.useridString forKey:@"user_id"];

            [defaults setValue:@"YES" forKey:@"hadLogin"];
            [defaults setValue:@"YES" forKey:@"guest"];

            [defaults synchronize];

            NSMutableDictionary *userInfoD = [[NSMutableDictionary alloc] init];
            [userInfoD setObject:self.phoneString forKey:@"telephone"];
            [userInfoD setObject:self.passwordString forKey:@"password"];
            [userInfoD setValue:self.useridString forKey:@"user_id"];
            [userInfoD setValue:@"YES" forKey:@"hadLogin"];
            [userInfoD setValue:@"YES" forKey:@"guest"];

            [User sharedInstance].userinfoDict = userInfoD;

在MoreViewController里面有个LogOutButton，当我点击LogOut我就把单例里面的hadLogin=NO

这是我的Modal

然后我在MyPropertyViewController里面调取userdefaults的user_id,代码如下

NSUserDefaults *myuserDefaults = [NSUserDefaults standardUserDefaults];
    if ([myuserDefaults objectForKey:@"user_id"]) {
        uid = [NSString stringWithFormat:@"%@", [myuserDefaults objectForKey:@"user_id"]];
    }
    else
    {
        uid = [NSString stringWithFormat:@"%@", [[User sharedInstance].userinfoDict objectForKey:@"user_id"]];
    }

Answer 1

为测试，可以自己尝试一下

可能是setValue引起，我也遇到过，不过已经很久了，是不是你可以自己改正下看：

在LoginViewController.m中

你的代码针对user_id进行了两次赋值，如下

[defaults setObject:self.useridString forKey:@"user_id"];
[defaults setValue:self.useridString forKey:@"user_id"];

建议删除setValue:self

[defaults setObject:self.useridString forKey:@"user_id"];

如果是这个原因，建议阅读setValue和setObject的区别

我也遇到了NSUserDefault 保存对象的登录问题，你是如何解决的？
