如何在Swift 4中從左到右更改導航動畫？

Question

我的應用程序中有一個導航欄，可以將導航更改為模態顯示，但是我希望當用戶轉到目標視圖控制器時，導航動畫從左到右

這是我在第一個視圖控制器中的代碼

    @IBAction func showProfilePage(_ sender: UIBarButtonItem) {


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


}

我為此閱讀了蘋果網站，也使用了此功能

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




}

但這不起作用，所以我應該怎么做才能從左到右更改導航動畫？

Answer 1

嘗試這個。

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)
