实现视图控制器之间的平滑自定义转换 swift

Question

can anyone help me fix this annoying jump/glitch bug when using a custom transition on view controller to view controller. I can't use push because I want to display the top navigation bar but hide the bottom tab bar so I have had to use a custom transition. I want to acheive a smooth transition like when going from view controller to view controller on a navigation controller. I have attached my code.

 func presentDetail(_ viewControllerToPresent: UIViewController) {
        let transition = CATransition()
        transition.duration = 0.25
        transition.type = CATransitionType.push
        transition.subtype = CATransitionSubtype.fromRight
        self.view.window!.layer.add(transition, forKey: kCATransition)
        present(viewControllerToPresent, animated: false)
    }

This is not so different from the comments given, however just some explanations that were not easy to add in comments.

I don't think what you see is a glitch, but a fade that is automatically applied with CATransition - you can see it slowed down.

You could go the CABasicAnimation or customizing UIViewControllerTransitions CATransition swift iOS but these will be a lot more work

I am not sure why hidesBottomBarWhenPushed does not work for you.

I have the following view hierarchy:

UITabBarController
   - UINavivationController (Tab 1)
     - UIViewController
   - UIViewController2 (Tab 2)

I now do this:

let dtvc = DetailTransitionVC()
dtvc.hidesBottomBarWhenPushed = true
navigationController?.pushViewController(dtvc, animated: true)

And this seems to give me what you want:
