Question

您好我有一个登录视图控制器和我的应用程序故事板视图。初始视图控制器指向应用程序仪表板。如果用户登录，我正在检查我的appDelegate应用程序功能。之后我（重新）设置正确的UIViewController作为初始。不知怎的，应用程序总是进入初始视图控制器，然后说oops我需要登录，因为用户没有登录...我怎么能避免这种情况？

这是我目前的代码。

dispatch_async(dispatch_get_main_queue(), {
    let storyboard: UIStoryboard = UIStoryboard.init(name: "Main", bundle: nil)
    if (settings.isLoggedIn())
    {
        let vc: AnyObject! = storyboard.instantiateInitialViewController()
        self.window?.rootViewController = vc as? UIViewController
    } else {
        let vc: AnyObject! = storyboard.instantiateViewControllerWithIdentifier("login")
        self.window?.rootViewController = vc as? UIViewController
    }
})

如何在appdelegate

中检查以下方法中登录的用户

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 

  //check user logged or not, if true you can set the initial view controller given below 

  let storyboard = UIStoryboard(name: "Main", bundle: nil)
  let vc : UIViewController! = storyboard.instantiateViewControllerWithIdentifier("urcontroller") 

  let window = UIApplication.sharedApplication().windows[0] ;
  window.rootViewController = vc;

  return true
}

在app完成加载之前确定初始视图控制器
