'update available' pop up not displaying

My app checks if there is update available in app store. I call this in didFinishLaunchingWithOptions method.

(BOOL)checkIfNeedsUpdate {
    BOOL needsUpdate = NO;
    NSDictionary* infoDictionary = [[NSBundle mainBundle] infoDictionary];

    NSString* appID = infoDictionary[@"CFBundleIdentifier"];
    NSURL* url = [NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/ph/lookup?bundleId=%@", appID]];
    NSData* data = [NSData dataWithContentsOfURL:url];
    NSDictionary* lookup = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];

    if([lookup[@"resultCount"] integerValue] == 1) {
        NSString* appStoreVersion = lookup[@"results"][0][@"version"];
        NSString* currentVersion = infoDictionary[@"CFBundleShortVersionString"];
        if(![appStoreVersion isEqualToString:currentVersion]) {
            [[NSUserDefaults standardUserDefaults] setBool:NO forKey:@"logined"];
            [[NSUserDefaults standardUserDefaults] synchronize];

            needsUpdate = YES;
        }
    }

    return needsUpdate;
}

So to test this, I downgraded the app version that I have and run it on the simulator and this works like a charm. However, when I try running the app on my device the "Update Available" pop up is not displaying thus not updating the app. Any idea what is wrong with my code? How can I display the "Update Available" pop up to be able to update.

Any help will be very much appreciated. Thanks in advance.

I was able to solve my problem. Thanks to @rokjarc's comment. Here's how I did it:

(void)checkIfNeedsUpdate {
    NSDictionary* infoDictionary = [[NSBundle mainBundle] infoDictionary];
    NSString* appID = infoDictionary[@"CFBundleIdentifier"];
    NSURL* url = [NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/ph/lookup?bundleId=%@", appID]];
    NSData* data = [NSData dataWithContentsOfURL:url];
    NSDictionary* lookup = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];

    if([lookup[@"resultCount"] integerValue] == 1) {
        NSString* appStoreVersion = lookup[@"results"][0][@"version"];
        NSString* currentVersion = infoDictionary[@"CFBundleShortVersionString"];
        if(![appStoreVersion isEqualToString:currentVersion]) {
            [[NSUserDefaults standardUserDefaults] setBool:NO forKey:@"logined"];
            [[NSUserDefaults standardUserDefaults] synchronize];
            [[Harpy sharedInstance] checkVersion];
        }
    }
}

I used Harpy - third party library to inform user's that there is an update for the app in app store. Thanks to the people who took a minute to read my inquiry.
