Question

Когда я изменяю ключевое окно, rootViewController(s) не получают представление будет / действительно появилось / исчезнет.

    SplashViewController *screenLockViewController = [[SplashViewController alloc] initWithNibName:@"SplashViewController" bundle:nil];
    [self.splashWindow.rootViewController presentViewController:splashViewController animated:NO completion:nil];

    [self.splashWindow makeKeyWindow];

    __weak typeof(self) welf = self;
    [UIView transitionWithView:self.window
                      duration:0.25
                       options:UIViewAnimationOptionTransitionNone
                    animations:^{
                        welf.window.alpha = 0.0f;
                    } completion:^(BOOL finished) {
                        [welf.window setHidden:YES];
                    }];
