I know this is probably very easy, but I want to add sprites in game that tell you have to play the game ONLY on the first launch. If the game is launched a second, third fourth, fifth, time etc. I do not want those instructions to appear again.

Could someone lead me in the right direction or give me an example?

I was thinking of adding a boolean "isFirstLaunch" then putting it in AppDelegate in "applicationDidFinishLaunching" then checking it in my game scene to see if it is true, but I'm not completely sure.

Any help?

Thanks!

  • If I wanted to do this on a normal computer, I would add a profile file at a known location on startup (if the file isn't there, that would mean first time startup). I don't know if the iphone API allows the creation of files somewhere? – Orka May 15 '11 at 03:06
  • I'm not sure about that. It is a good idea though. – Jonathan May 15 '11 at 03:08

Just use the default preferences. If the app doesn't find the file = first time, if the app does find the file = not first time. I did something like this when I was programming LustCalc. Look for NSUserDefaults... something. Sorry I did this a long time ago.

Found this: Best way to check if an iPhone app is running for the first time

as a side note, if you don't use synchronize, the iphone decide when to store the preferences, usally after a minute or two: if the app quits in the meantime, no preferences get saved. So you should sync only when you quit the app and at exceptional times.
