我有一个应用程序将用户的会话存储在NSUserDefaults中.当应用程序被强制关闭时,在初始验证数据控制器是否存在用户会话,以防如果将其发送到启动窗口,如下所示:

override func viewWillAppear(animated: Bool) {

    self.view.hidden = true

    let defaults = NSUserDefaults.standardUserDefaults()
    if   defaults.stringForKey("user") != nil
    {

        dispatch_async(dispatch_get_main_queue(), { () -> Void in
            let viewController:UIViewController = self.storyboard?.instantiateViewControllerWithIdentifier("vistaInicio") as! ViewControllerInicio
            self.presentViewController(viewController, animated: true, completion: nil)
        })


    }else
    {
    self.view.hidden = false

    }

}

直到今天,当我决定 在iOS上设置Firebase云消息客户端应用程序后,根据本教程更新firebase实施推送通知,这一直顺利进行.当他杀死应用程序并再次输入时出现问题,提供以下错误代码:
