Presenting walkthrough in iOS app

Solution
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"];
Problem
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]; } ```
