Showing/dismissing a walkthrough - iOS Application structure

Question

I need to present the classic walkthrough when the Application get launched the first time but, with the implementation that I have in mind, I end up with a structure that keeps the walkthrough as first controller of the hierarchy... and I don't like that. Here is a description of my implementation:

1) In the didFinishLaunchingWithOption I check UsereDefault to catch the first launch

2) If is the first launch I substitute the rootViewController of the window with the walkthrough

3) When the walkthrough is finished I present the first view controller of the App

The problem is with point 3. Presenting the controller from the walkthrough I end up with the whole application presente as modal of the walkthrough... what I want is to completely substitute the walkthrough with the standard first view controller.

Could you suggest a good pattern to show/dismiss a walkthrough?

Does your app use a nav controller? Does the walk through? – Wain Jan 25 '15 at 09:13 — Wain, Jan 25 '15 at 09:13

When you finish Walk-through, replace the rootViewController of your window.

FirstViewController *firstVC = [[FirstViewController alloc] init];
yourAppDelegate.window.rootViewController = firstVC;

Or if you are using storyboard:

FirstViewController *firstVC = (FirstViewController *)[[UIStoryboard storyboardWithName:@"YourStoryboardName" bundle: nil] instantiateViewControllerWithIdentifier:@"YourFirstVCId"];
yourAppDelegate.window.rootViewController = firstVC;

Another option is Show the Walkthrough as modal on top of FirstViewController if it's first time.

Is there a way to perform a smooth transition? changing the rootController that way has a terrible gfx effect. – MatterGoal Jan 25 '15 at 09:46
You need to write some custom animation for that. – Midhun MP Jan 25 '15 at 22:43
