禁用segue动画 [英] Disabling segue animation

问题描述

我想在我的故事板中显示（例如推送）segues，以连接我的viewcontrollers和我的导航控制器。然后，viewcontrollers上的导航栏将正确显示。
例如：使用show detail或present modaly，导航栏将消失

I want to Show (e.g. push) segues in my storyboard, to connect my viewcontrollers and my navigation controller. Then the navigation bars on the viewcontrollers will show correctly. For example: With show detail or present modaly, the navigation bar will disappear

但我不想要segue动画。
Xcode发出如下警告：在iOS 9.0之前禁用segue动画

But I don't want segue animation. Xcode is giving the warning like : "Disabling segue animation is not available prior to iOS 9.0"

我想要iOS 7.0或8.0的部署目标

And I wants deployment target of iOS 7.0 or 8.0

如何解决这个问题？

提前致谢。

推荐答案

您可以在执行segue之前和再次启用之后禁用动画。

You can disable animations before performing the segue and after enable it again.

UIView.setAnimationsEnabled(false)
self.performSegueWithIdentifier("next", sender: nil)
UIView.setAnimationsEnabled(true)

这将执行没有动画的segue。

This will perform the segue without the animation.
