如何使用Swift在iOS中从右到左显示视图控制器

Question

我正在使用presentViewController呈现新屏幕

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

这将显示从下到上的新屏幕，但是我希望它不使用UINavigationController就从右到左显示。

我使用的是Xib而不是情节提要，我该怎么做？

Answer 1

您使用的是xib还是storyboard都没有关系。通常，将视图控制器推入演示者的UINavigiationController时会使用从右向左的过渡。

UPDATE

添加了计时功能kCAMediaTimingFunctionEaseInEaseOut

Sample project，将Swift 4

实现添加到GitHub

Swift 3和4.2

let transition = CATransition()
transition.duration = 0.5
transition.type = CATransitionType.push
transition.subtype = CATransitionSubtype.fromRight
transition.timingFunction = CAMediaTimingFunction(name:CAMediaTimingFunctionName.easeInEaseOut)
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)
似乎类似于animated方法中的presentViewController参数，在这种情况下，自定义过渡并不重要。它可以是任何值，true或false。

Answer 2

let transition = CATransition()
    transition.duration = 0.25
    transition.type = kCATransitionPush
    transition.subtype = kCATransitionFromLeft
    transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionLinear)
    tabBarController?.view.layer.add(transition, forKey: kCATransition)
    self.navigationController?.popToRootViewController(animated: true)

Answer 3

如果您想保留Apple的经典动画，而又没有看到使用CATransition（）看到的“黑色”过渡，我有一个更好的解决方案对我有用。只需使用popToViewController方法。

Answer 6

阅读所有答案，看不到正确的解决方案。正确的方法是为呈现的VC委托创建自定义UIViewControllerAnimatedTransitioning。

Answer 7

您也可以使用自定义序列。
