从今日扩展/小工具打开设置应用程序？

Question

是否可以从widget / today扩展程序直接打开“设置”应用程序？

我已尝试过以下代码，但遗憾的是它无效

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

Answer 1

此代码应该正常工作

        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
                }
            }
        })

但我不确定＆＃34;其他评论＆＃34;手段
