在Swift中创建滑动序列 [英] Creating a sliding segue in Swift

问题描述

我正在尝试在两个滑动到下一个View Controller的View Controller之间创建序列/过渡。我所说的滑动是指它的移动幅度仅为平移手势的平移幅度（类似于Snapchat）。如果您可以为我提供帮助，或者只是为我指明正确的方向，那就太好了。

I am trying to create a segue/transition between two View Controllers that "slides" to the next View Controller. What I mean by "slide" is that it only moves as much as the translation of a pan gesture(similar to Snapchat). If you could help me with this or just point me in the right direction, that would be great.

推荐答案

可以达到这种效果使用自定义互动过渡，这是iOS7中引入的。以下是一些要检查的教程：

That effect is achieved using custom interactive transitions, which were introduced in iOS7. Here are a few tutorials to check out:

当我实现此功能时，我发现可重用性，最好是有一个 UIPercentDrivenInteractiveTransition （我们称为 TransitionManager ）的子类来实现协议 UIViewControllerTransitioningDelegate ， UINavigationControllerDelegate 和 UIViewControllerAnimatedTransitioning 。

When I was implementing this I found that, for reusability, it was best to have one subclass of UIPercentDrivenInteractiveTransition (which we'll call TransitionManager) that implemented the protocols UIViewControllerTransitioningDelegate, UINavigationControllerDelegate and UIViewControllerAnimatedTransitioning.

-然后，如果您需要以自定义过渡方式模态显示 UIViewController ：在 prepareForSegue 中设置：

- Then, if you need to present a UIViewController modally with your custom transition: in prepareForSegue set:

destinationViewController.modalPresentationStyle = .Custom
destinationViewController.transitioningDelegate  = TransitionManager()

-使用 UINavigationController 会更容易，您所需要做的只是设置 UINavigationController 的委托到您的 TransitionManager 。

- If you're using a UINavigationController it's even easier, all you need to do it set the UINavigationController's delegate to your TransitionManager.

希望当您阅读完这些教程后，这应该会变得有意义。

Hopefully that should start to make some sense once you've gone through the tutorials.
