overAiding shouldAutorotate不在Swift 3中工作 [英] overriding shouldAutorotate not working in Swift 3

问题描述

我正试图阻止一个 UIViewController 的轮换，我无法实现。

I'm trying to prevent rotation on one UIViewController and I can't achieve that.

I做这样的事情：

open override var shouldAutorotate: Bool {
    get {
        return false
    }
}

override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
    get {
        return .portrait
    }
}

UIViewControler 仍然在旋转。 UIViewController在一个模态打开的UINavigationController里面。

And the UIViewControler stills rotating. The UIViewController is inside a UINavigationController opened modally.

我从这里看了很多问题，没有一个答案适合我。

I have looked a lot of questions from here and none answers works for me.

在Swift 2中我曾经覆盖 shouldAutorotate ，但在Swift 3中，该函数不再存在。

In Swift 2 I used to override shouldAutorotate but in Swift 3 that function doesn't exist anymore.

我如何在Swift 3中做到这一点，我曾经在Swift 2中做过什么？

How can I do that in Swift 3 what I used to do in Swift 2?

推荐答案

我不知道如果我可以多次重现这种行为，为什么要投票结束这个问题。 UIViewController 位于以模拟方式打开的 UINavigationController 内。

I don't know why is a vote to close the question if I can reproduce this behavior a lots of times. The UIViewController is inside a UINavigationController opened modally.

这就是我为解决问题所做的工作。

This is what I did to solve the problem.

我创建了这个类，并设置为 UINavigationController 我希望阻止旋转的 UIViewController

I create this class and I set to the UINavigationController that containt the UIViewController that I want to prevent to rotate

class NavigationController: UINavigationController { 

    override var shouldAutorotate: Bool {
        return false
    }

    override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
        return .portrait
    }

}

就是这样，它对我有用
