我在哪里注册registerDefaults？

Question

我想加载并保存设置。我不知道我把registerDefaults放在哪里。 我把它放在loadSetting中。我想我做错了。我是否必须在申请结束时把它放在didFinishLaunch？

  - (void)loadSettings {    
        NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

        NSDictionary *dictionary = [NSDictionary dictionaryWithObjectsAndKeys:
                         [NSNumber numberWithBool:YES], @"key1",
                         [NSNumber numberWithBool:NO], @"key2",
                         nil];
        [defaults registerDefaults:dictionary];

        key1Value = [defaults boolForKey:@"key1"];
        key2Value = [defaults boolForKey:@"key2"];
    }

    -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:  NSDictionary *)launchOptions  {    
        [self loadSettings];

    }

对我来说没问题。我想只要你在加载任何视图之前调用它，你应该没问题。
