Answer 1

You could use NSUserDefaults for this:

    NSUserDefaults * userDefaults = [NSUserDefaults standardUserDefaults];
    NSInteger appLaunchAmounts = [userDefaults integerForKey:@"LaunchAmounts"];
    if (appLaunchAmounts == 10)
    {
        [self showMessage];
    }
    [userDefaults setInteger:appLaunchAmounts+1 forKey:@"LaunchAmounts"];

Answer 2

You can store that into the NSUserDefaults . Just update it in applicationDidFinishLaunching: .

Answer 3

You can save an integer in NSUserDefaults

- (void)setInteger:(NSInteger)value forKey:(NSString *)defaultName

Retrieve it and increment it every time the appDidFinishLaunching (or appWillEnterForeground) delegate methods is called. Probably best to use appWillEnterForeground as sometimes apps can lie in the background unterminated for days.

NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
NSInteger count = [defaults integerForKey:@"LaunchCount"];
count++;
/* Do checks and review prompt */
[defaults setInteger:count forKey:@"LaunchCount"];
[defaults synchronize];

Answer 4

This will store a value in NSUserDefaults called 'AppLaunchCount'.

- (BOOL)application:(UIApplication *)app didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {


if ([[NSUserDefaults standardUserDefaults] integerForKey:@"AppLaunchCount"])
{
    [[NSUserDefaults standardUserDefaults] setInteger:([[NSUserDefaults standardUserDefaults] integerForKey:@"AppLaunchCount"] + 1) forKey:@"AppLaunchCount"];
}
else
{
    [[NSUserDefaults standardUserDefaults] setInteger:1 forKey:@"AppLaunchCount"];
}
}
