Is it possible to check when user downloaded my ios app? [duplicate]

Answer 1

I'm not sure if there's a way to automatically check a download date.

But you can certainly set a date for when the app was very first launched. In your appDidFinishLaunching method in your app delegate:

if (![[NSUserDefaults standardDefaults] objectForKey:@"FirstLaunch"]) {
    [[NSUserDefaults standardDefaults] setObject:[NSDate date] forKey:@"FirstLaunch"];
}

Any point after this, you can check this date and compare it to whatever you want.
