Load and Display View While Interstitial is Shown

Question

I have a UiViewController1 that loads an Admob interstitial, displays it when the user clicks a button, and loads another UiViewController2 when the user clicks out of the ad. However, I don't want the previous viewController to show, and the Admob interstitials are presented animated (I don't know of a way to stop this):

-(void)viewDidLoad {
    [super viewDidLoad];

    interstitial = [[GADInterstitial alloc] init];
    interstitial.adUnitID = @"ca-app-pub-7102519969826764/7522738211";
    interstitial.delegate = self;

    GADRequest *request = [GADRequest request];
    request.testDevices = [NSArray arrayWithObjects:GAD_SIMULATOR_ID,@"TheIDAppearingInLogs",nil];
    [interstitial loadRequest:request];   
}

-(void)onButtonPush {
    if (interstitial.isReady) {
        [interstitial presentFromRootViewController:self];
    } else {
        UIViewController2 *viewController = [[UIViewController2 alloc] init];
        [self presentViewController:viewController animated:NO completion:nil];
    }
}

-(void)interstitialDidDismissScreen:(GADInterstitial *)ad {
    UIViewController2 *viewController = [[UIViewController2 alloc] init];
    [self presentViewController:viewController animated:NO completion:nil];
}

I tried to load UIViewController2 before the ad is dismissed but, this happens:

Attempt to present <UIViewController1: 0x1355816a0> 
on <UIViewController2: 0x135506490> whose view is not in the window hierarchy!

Answer 1

I guess you CANNOT modify AdMob SDK's viewController presenting behaviour, actually what you are doing is not really common.

I would suggest to do some workaround f.e adding your viewController2 as a child instead of presenting modally in interstitialdidDismiss delegate
