如何使用Swift在iOS中从右到左呈现视图控制器 [英] How to present view controller from right to left in iOS using Swift

问题描述

我正在使用presentViewController来呈现新屏幕

I am using presentViewController to present new screen

let dashboardWorkout = DashboardWorkoutViewController()
presentViewController(dashboardWorkout, animated: true, completion: nil)

这会从下到上显示新屏幕，但我想要它呈现从右到左不使用 UINavigationController 。

This presents new screen from bottom to top but I want it to presented from right to left without using UINavigationController.

我使用的是Xib而不是故事板，所以我该怎么做？

I am using Xib instead of storyboard so how can I do that ?

推荐答案

如果您使用的是 xib 或 storyboard ，则无关紧要。通常，当您将视图控制器推送到presentor的 UINavigiationController 时，会使用从右到左的过渡。

It doesn't matter if it is xib or storyboard that you are using. Normally, the right to left transition is used when you push a view controller into presentor's UINavigiationController.

更新

添加计时功能 kCAMediaTimingFunctionEaseInEaseOut

示例项目，其中添加了 Swift 4 实施GitHub

Sample project with Swift 4 implementation added to GitHub

Swift 3& 4

let transition = CATransition()
transition.duration = 0.5
transition.type = kCATransitionPush
transition.subtype = kCATransitionFromRight
transition.timingFunction = CAMediaTimingFunction(name:kCAMediaTimingFunctionEaseInEaseOut)
view.window!.layer.add(transition, forKey: kCATransition)
present(dashboardWorkout, animated: false, completion: nil)

ObjC

CATransition *transition = [[CATransition alloc] init];
transition.duration = 0.5;
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[transition setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[self.view.window.layer addAnimation:transition forKey:kCATransition];
[self presentViewController:dashboardWorkout animated:false completion:nil];

Swift 2.x

let transition = CATransition()
transition.duration = 0.5
transition.type = kCATransitionPush
transition.subtype = kCATransitionFromRight
transition.timingFunction = CAMediaTimingFunction(name:kCAMediaTimingFunctionEaseInEaseOut)
view.window!.layer.addAnimation(transition, forKey: kCATransition)
presentViewController(dashboardWorkout, animated: false, completion: nil)

好像是动画参数在这个自定义转换的情况下， presentViewController 方法并不重要。它可以是任何值， true 或 false 。

Seems like the animated parameter in the presentViewController method doesn't really matter in this case of custom transition. It can be of any value, either true or false.
