Click animation without shadows and blackouts

I have a simple iOS application NavigationController. Two UICollectionViews, one by one. If you click an item in the β€œfirst collection,” the second collection will open . ” Pretty simple.

Important Note:

"Both UICollectionViewshave a transparent background. The common background color is used for NavigationController(Inherited class from UINavigationController)"

Problem: If understood correctly, the push method NavigationControllerworks in accordance with the algorithm:

  • A compression view is created.
  • Transparent gray overlay created on top .
  • NavigationController pushes the view with standard animation. (The gray overlay is still there)
  • The gray overlay disappears.

(If you click on a transparent background, a gray vertical line is visible )

Next step: I tried to solve this problem by overriding the push method. Here is what I have:

- (void)pushViewController:(UIViewController *)viewController 
                           animated:(BOOL)animated
{
    CATransition *transition = [CATransition animation];
    transition.duration = 0.45;
    transition.timingFunction = [CAMediaTimingFunction 
           functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionPush;
    transition.subtype = kCATransitionFromRight;
    transition.fillMode = kCAFillModeForwards;
    transition.delegate = self;
    [self.view.layer addAnimation:transition forKey:nil];

    [super pushViewController:viewController animated:animated];
}

This method creates its own push animation, but there were other standard animations that I can’t remove. (Blackout when presenting and hiding views)

Question: "How can I click on the ViewController without fading, dimming, or other animation filters?"
