How to implement instruction view for iPhone app

Question

I have 2 pages that I want to show as instructions the first time the app is run. How would I accomplish this?

Are you asking how to know if this is the first time the app had been run or how to show these two pages? If first, then take a look at http://stackoverflow.com/questions/9964371/how-to-detect-first-time-app-launch-iphone — Rok Jarc, Jun 14 '12 at 19:04

@CodaFi it's better to ask an expert on the proper way to do this as it's been done countless times before — Kyle, Jun 14 '12 at 19:32
@Kyle: Is that to imply that I lack credibility? No matter, the links I have provided are excellent reading. Though, I would suggest you reword this question before it is closed for literally being `not a question` — CodaFi, Jun 14 '12 at 19:34
@Kyle: Trolling? The second link is standard reading for people who need us to "show them teh codez." To think that I would even have the slightest reason to falsify or "lead on" is a serious misjudgment of my character. Lest this become a flame war, I bid you good day, sir. — CodaFi, Jun 26 '12 at 02:49

You can utilize NSUserDefaults for something like this.

    if(![[NSUserDefaults standardUserDefaults] boolForKey:@"didLoad"]) {

          //Show your instructions

       [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"didLoad"];
       [[NSUserDefaults standardUserDefaults] synchronize];

    }

What this does is, check if the didLoad bool is FALSE (Which will be on first Load), if it is you show your instructions and set the BOOL to YES for the next Launch. You can put this in your viewDidLoad method.
