问题
I have navigation controller based project. In my project I have Splash Screen & Login Screen where i have hidden the navigation controller.
Now i have to implement TabbarController in the application and It need to be shown the screen after Login Page.
I want to add it in AppDelegate.But my problem is that I have set rootviewcontroller of Window as navigation controller.
And Now i want to use Tabbar controller also into the Appdelegate class.
I am finding difficulty into it.
Any help will be appreciated a lot.
回答1:
What you can do is set the rootviewcontroller as a tabbarcontroller and add a tab for your login screen but make sure to hide the tabbar initially, after the user login, you can remove the tab programatically and show the tabbar.

Maybe you really need that kind of navigation in your application, to me it sounds a bit of a unnecessary workaround and against guidelines. Try having a look at Apple's ("View Controller Programming Guide > Combined View Controller Interfaces") and maybe you'll find a more elegant solution to your problem.
