iOS 10和Swift 2.3中的supportInterfaceOrientations [英] supportedInterfaceOrientations in iOS 10 and swift 2.3

问题描述

我正在使用Xcode 8 GM，并且有一个旧项目需要为iOS 10更新.

I am using Xcode 8 GM and have an old project that need updating for iOS 10.

我发现在iOS 10上运行时，当前使用Swift 2.2版本的应用商店构建不支持所需的界面定向功能

I have found that my current appstore build using version 2.2 of Swift is not supporting the desired interfaceorientation functionality when running on iOS 10

当我覆盖supportedInterfaceOrientations()时，简而言之，它在iOS 10上运行时永远不会被调用.

Simply put when I override supportedInterfaceOrientations() it never gets called when running on iOS 10.

在以前的版本中，它工作正常.

On previous versions it works fine.

我可以看到签名已经更改，因此supportedInterfaceOrientations现在是一个变量，而不是方法，但这似乎仅适用于Swift 3，而不适用于Swift 2.3.当我尝试在Swift 2.3中重写为var时，它将无法编译，并且如果使用旧签名，它将永远不会在iOS 10下被调用

I can see that the signature has changed so that supportedInterfaceOrientations is now a var and not a method but this only seem to apply to Swift 3 and not to Swift 2.3. When I try to override as a var in Swift 2.3 it will not compile and if I use the old signature it never gets called under iOS 10

有什么想法吗?

推荐答案

对于ios 10，Swift 3.0

For ios 10, Swift 3.0

override var supportedInterfaceOrientations:UIInterfaceOrientationMask {
        return UIInterfaceOrientationMask.all
    }
