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，但我希望不使用即可从右到左显示UINavigationController。

我使用的是Xib而不是情节提要，该怎么办？

回答：

是否使用xib或storyboard正在使用都没有关系。通常，当您将视图控制器推入Presentor时，使用从右向左过渡UINavigiationController。

新增计时功能 kCAMediaTimingFunctionEaseInEaseOut

示例项目与

实现加入GitHub上

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)

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];

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)

在自定义转换的情况下，方法中的animated参数presentViewController似乎并不重要。它可以是任何值，true或者false。
