如何在swift 4中将导航动画从左到右更改？

Question

我的应用程序中有一个导航栏，我将导航更改为模态显示但是当用户转到目标视图控制器时，我希望导航动画从左到右

这是我在第一个视图控制器中的代码

    @IBAction func showProfilePage(_ sender: UIBarButtonItem) {


    self.performSegue(withIdentifier: "showprofile", sender: self)


}

我为此阅读了苹果网站并使用了此功能

private func navigationController(_ navigationController: UINavigationController,
                                   willShow viewController: ProfileViewController,
                                   animated: Bool) {




}

但它不起作用所以我应该怎么做才能从左到右更改导航动画？

Answer 1

试试这个。

let storyBoard : UIStoryboard = UIStoryboard(name: "PatientCheckout", bundle:nil)
let controller = storyBoard.instantiateViewController(withIdentifier: "PatientCheckoutViewController") as UIViewController

let transition = CATransition.init()
transition.duration = 0.45
transition.timingFunction = CAMediaTimingFunction.init(name: kCAMediaTimingFunctionDefault)
transition.type = kCATransitionPush //Transition you want like Push, Reveal
transition.subtype = kCATransitionFromLeft // Direction like Left to Right, Right to Left
transition.delegate = self
view.window!.layer.add(transition, forKey: kCATransition)
self.navigationController?.pushViewController(controller, animated: true)
