Question

I’m trying to create an app using storyboard which has 4 scenes:

• ChooseLoginMethod
• EnterLoginData
• SuccessfulLogin
• MainScene.

What I’m doing right now is the following: I have an UINavigationController which has ChooseLoginMethod as its root view. ChooseLoginMethod has several buttons (for different login methods) which are push segues to EnterLoginData. EnterLoginData has a push segue to SuccesfullLogin and SucessfullLogin has a push segue to MainScene.

The problem is that SuccessfulLogin and MainScene display the back button on the top bar, which makes no sense for the application.

I’ve tried:

• Hidding the top bar on these two Views. Not successful.
• Changing the segue to modal. Seems to work, but doesn’t feel like the right thing to do.

So what I would like to do is create a segue which breaks the chain of Views which are on the UINavigationController’s stack. Is there a proper way to do this in storyboard?

— edit —

Maybe what I should do is replace the root view ( Set root view for UINavigationController ). This may work, but seems like a programming work-around for something that should be possible to be done in storyboard. Or maybe it is just me not getting the “iOS way of doing stuff”.

I think it’s usually best to have your main scene be the root view controller. From its viewDidAppear method, you can present your ChooseLoginMethod controller modally, and from there do modal transitions to your other login controllers. When you get to the end, and you want to go back to the main scene just dismiss the modals from the root view controller — this will dismiss the first one, and any that were presented from it:

[self.view.window.rootViewController dismissViewControllerAnimated:YES completion:nil];
