如何手动设置要在应用委托中显示的故事板视图 [英] How to manually set which storyboard view to show in app delegate

我有一个应用程序想要在应用程序处于非活动状态一段时间后注销用户。这是应用程序中的多个不同视图，我希望应用程序委托在此方法触发时将loginview设置为当前视图：

I have an app that wants to log out user whenever application is inactive for a set period of time. It's multiple different views in the app, and i want the app delegate to set loginview as current view whenever this method fires:
