如何在 iOS 15 上使用 UIWindowScene.windows? [英] How to use UIWindowScene.windows on iOS 15?

问题描述

目前，在 iOS 14.6 中，我可以使用以下代码在我的应用中调用一个显示共享表的函数:

Currently, with iOS 14.6, I can call a function in my app that displays a share sheet using the following code:

func share(link: URL) {
    let activityView = UIActivityViewController(activityItems: [link], applicationActivities: nil)
    UIApplication.shared.windows.first?.rootViewController?.present(activityView, animated: true, completion: nil)
}

从 iOS 15 测试版开始，Xcode 告诉我'windows' 在 iOS 15.0 中被弃用:在相关的窗口场景中使用 UIWindowScene.windows".我如何更新它，以便我的共享表可以在这个新版本中正常工作?谢谢！

Since iOS 15 beta, Xcode tells me "'windows' was deprecated in iOS 15.0: Use UIWindowScene.windows on a relevant window scene instead". How can I update this so that my share sheet will work properly in this new version? Thanks!

推荐答案

这对我有用并且没有产生任何警告:

This worked for me and didn't produce any warnings:

let keyWindow = UIApplication.shared.connectedScenes
        .filter({$0.activationState == .foregroundActive})
        .map({$0 as? UIWindowScene})
        .compactMap({$0})
        .first?.windows
        .filter({$0.isKeyWindow}).first
