I am relatively new to IOS interface design, and currently facing this problem:

I am having an app wanted to have a tutorial (UIPageViewController) ahead of the navigationcontroller, which will be the main controller on storyboard that the app will enter with.

Now, what I want to achieve is let the app run my Tutorial Pages ahead for first time of app running, then enter the NavigationController. If it is not the first time, user will go to NavigationController directly.

After some research, I found out there are at least two ways of doing it:

  1. Programming the UIPageViewController totally on code, then in Appdelegate, having an if-else loop to do this.
  2. Insert the UIPageViewController into the storyboard and do it.

So far those are two ways I can find out. For second however, I can't find an optimal way to handle "skipping the tutorial page completely". Or probably there is a better way of doing this. I want the app to be more optimal, and wondering what is the usual way of doing it for an IOS professional's choice.

Thank you!

(p.s. If the question is a repeated one or not clear, please leave me comments. Thanks again! It is possible bonus for if can show some links for github demo.)

The way I normally do this sort of thing is as follows:

  1. Put the tutorial content in a separate storyboard.
  2. In the initial view controller of the main storyboard, check a dedicated variable in the NSUserDefaults to see if user has ever run the app before.
  3. If not, then programmatically load up the initial view controller of the tutorial storyboard and present it.

This way, the main storyboard isn't loaded up with a bunch of view controllers that are only used once, and there is minimal code to write for the transition.

-- EDIT --

Below is a Swift version of the answer to this question: How can I load storyboard programmatically from class?

let storyboard = UIStoryboard(name: "Tutorial", bundle: nil)
let viewController = storyboard.instantiateInitialViewController()
presentViewController(viewController, animated: true, completion: nil)

  • Do you know some good tutorial for the separate storyboard? Including calling it from viewcontroller, and targeting viewcontroller. This is my first time encountering UI. Thanks! – windsound Oct 03 '15 at 04:00
  • I added some sample code. Wrap it in an if block that checks the value of an `NSUserDefault`. – Daniel T. Oct 03 '15 at 12:33
  • Well, after implementation, I found out it can't be simply do that with navigation controller with your way... – windsound Oct 03 '15 at 15:19
  • I can' think of any reason why the above code wouldn't work in a navigation controller. What problem are you having? – Daniel T. Oct 03 '15 at 16:27
  • The thing related to navigation controller, unbalanced call, have fixed it :) – windsound Oct 03 '15 at 16:38
  • Glad you fixed it. The unbalanced call error means you tried to present a view controller in the middle of presenting a view controller. – Daniel T. Oct 03 '15 at 16:41

this link has sample project for that but it is written in Objective-C. https://github.com/MatthewYork/MYBlurIntroductionView
