Discovering the iOS App Purchase Date

Question

I\'m explicitly NOT referring to in-app purchases.

Is it possible to discover the purchase date of the application itself on iOS?

I\'d like to reward early

Answer 1

I am almost positive this is impossible by any method.

HOWEVER you could potentially store the date of their first "launch" of the application then do whatever you wanted with it.

if ([[[[NSUserDefaults standardUserDefaults] dictionaryRepresentation] allKeys] containsObject:@"firstLaunch"]) {
    [[NSUserDefaults standardUserDefaults] setObject:[NSDate date] forKey:@"firstLaunch"];
}

NSDate *firstLaunch = [[NSUserDefaults standardUserDefaults] objectForKey:@"firstLaunch"];

if (firstLaunch < Cutoff) {
    // Do Something
}
