ios - 更改rootViewController时从正确的动画滑动

Question

我正在尝试使用从右滑动的动画来更改rootViewController。

我知道如何使用翻转动画:

let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let viewController = mainStoryboard.instantiateViewControllerWithIdentifier("LandingViewController") 


UIView.transitionWithView( UIApplication.sharedApplication().keyWindow!,
                           duration: 0.5,
                           options: UIViewAnimationOptions.TransitionFlipFromLeft,
                           animations: { UIApplication.sharedApplication().keyWindow?.rootViewController = viewController; },
                           completion: nil)

但是，UIViewAnimationOptions没有从右向滑动的动画。
我该如何实现？

Answer 1

试试这个

let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let viewController = mainStoryboard.instantiateViewControllerWithIdentifier("LandingViewController") 

let navigationController = UIApplication.sharedApplication().keyWindow?.rootViewController.navigationController

//first push the viewController
navigationController?.pushViewController(viewController, animated: true)

然后，在viewController的viewDidAppear处，您应该执行此代码

//remove all previous controllers in the stack by settings viewControllers stack with only current viewController
self.navigationController?.viewControllers = [self]

希望对您有所帮助
