从今天 Extension/Widget 打开“设置”应用？

Question

是否可以直接从 widget/today 扩展程序打开“设置”应用程序？

我试过下面的代码，但遗憾的是它不起作用

let url = URL(string:UIApplicationOpenSettingsURLString)!
extensionContext?.open(url) { _ in }

Answer 1

此代码应该有效


        guard let url = URL(string: UIApplicationOpenSettingsURLString) else {
            return
        }
        extensionContext?.open(url, completionHandler: { (success) in
            if !success {
                var responder = self as UIResponder?

                while (responder != nil){
                    let selectorOpenURL = NSSelectorFromString("openURL:")
                    if responder?.responds(to: selectorOpenURL) == true {
                        _ = responder?.perform(selectorOpenURL, with: url)
                    }
                    responder = responder?.next
                }
            }
        })

不过我不确定 "additional review" 是什么意思
