thanks in advance!

and here startgamingwithconfig

- (void) startgamewithconfig:(gameconfig *)config { // fade in loading screen hide load time [_loadingview sethidden:no]; [_loadingview setalpha:0.0f]; [uiview animatewithduration:0.2f delay:0.0f options:uiviewanimationoptioncurvelinear animations:^{ [_loadingview setalpha:0.0f]; } completion:^(bool finished){ cardsviewctrl* newcontroller = [[cardsviewctrl alloc] init]; newcontroller.gameconfig = config; appdelegate *delegate = (appdelegate *)[[uiapplication sharedapplication] delegate]; [delegate.navcontroller pushfadeinviewcontroller:newcontroller animated:yes]; }]; }

instead of using presentmodelviewcontroller use:navigationcontroller

- (ibaction)retour:(id)sender { rootviewcontroller *b = [[rootviewcontroller alloc] init]; [self.navigationcontroller pushviewcontroller:b animated:yes]; }
