Question

How can I make an app play a video walkthrough (only) the first time it is loaded and then close itself and not play the next time user uses the app?
I found some instructions on showing a pop-up message but this didn’t help really :/

Answer 1

On launch read a setting from NSUserDefaults. If not present play the video. When the video finishes write that same setting to NSUserDefaults. In the next launch the setting will be found and you can skip the video part.

if ([[NSUserDefaults standardUserDefaults] boolForKey:@"firstLaunch"];) {
    // play the video
    // when done:
    [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"firstLaunch"]
} 

Not sure if you’re asking how to play the video too. If that’s the case, you may want to split the question in two and be more specific.
