Presenting walkthrough in iOS app

Question

I am pushing out version 2 of my app and need a short walkthrough of the new features. I went through a tutorial and created my walkthrough in another app, with one UIViewController that is root view, a UIPageViewController which contains one UIView where I display my screens. It works as I want it.

Now I want to integrate this in my app. I can easily import my coding from the sample app.

I believe in the app delegate I will see if the user has ever been through the walkthrough, and if not, switch to the UIViewController that starts the walkthrough, and write to a default that the user has seen the walkthrough (so they don't need to see it again). I have a button in the walkthrough to go the main screen.

My partial code for the method "applicationdidFinishLaunchingWithOptions is below:

                - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
        UIPageControl *pageControl = [UIPageControl appearance];
        pageControl.pageIndicatorTintColor = [UIColor lightGrayColor];
        pageControl.currentPageIndicatorTintColor = [UIColor blackColor];
        pageControl.backgroundColor = [UIColor whiteColor];

        UIStoryboard *storyBoard;
        storyBoard = [UIStoryboard storyboardWithName:@"MainStoryboard.storyboard" bundle:nil];
        UIViewController *walkthrough = [storyBoard instantiateViewControllerWithIdentifier:@"NextViewController"];
        //[self presentViewController:walkthrough animated:YES completion:nil];
        [self.window setRootViewController:walkthrough];

        return YES;
    }

Here is the completed code that works. Thanks very much for the help:

      // User Defaults
      UserDefaults *thisUserDefaults = [[UserDefaults alloc] init];
      [thisUserDefaults registerDefaults];

      if (![[[NSUserDefaults standardUserDefaults]
              valueForKey:kAppHasRunBeforeKey] boolValue]) {

        UIPageControl *pageControl = [UIPageControl appearance];
        pageControl.pageIndicatorTintColor = [UIColor lightGrayColor];
        pageControl.currentPageIndicatorTintColor = [UIColor blackColor];
        pageControl.backgroundColor = [UIColor whiteColor];

        UIStoryboard *storyBoard;
        storyBoard = [UIStoryboard storyboardWithName:@"Main_iPhone" bundle:nil];
        UIViewController *walkthrough =
            [storyBoard instantiateViewControllerWithIdentifier:@"ViewController"];
        [self.window setRootViewController:walkthrough];

        [[NSUserDefaults standardUserDefaults] setBool:YES
                                                forKey:kAppHasRunBeforeKey];
      }

Answer 1

The best and easiest possible method to show tips would be to use this library: https://github.com/chrismiles/CMPopTipView

Otherwise, if you want to do it with the approach you mentioned then you will need to keep a variable in NSUserDefaults lets say a bool walkthroughShownOnce. Initially if you are accessing the variable in the app delegate from NSUserDefaults like this:

bool tempInt = [[NSUserDefaults standardUserDefaults] boolForKey:@"walkthroughShownOnce"];

then it will return false. This is when you show your walkthrough and in the end after you have shown the walk through, simply make the variable true like this:

[[NSUserDefaults standardUserDefaults] setBool:TRUE forKey:@"walkthroughShownOnce"];

There's this library too SwiftyWalkthrough.
