iOS 11，一些权限设置已经移动到应用程序路径:

iOS 11支持

 static func open(_ preferenceType: PreferenceType) throws {
    var preferencePath: String
    if #available(iOS 11.0, *), preferenceType == .video || preferenceType == .locationServices || preferenceType == .photos {
        preferencePath = UIApplicationOpenSettingsURLString
    } else {
        preferencePath = "\(PreferencesExplorer.preferencePath)=\(preferenceType.rawValue)"
    }

    if let url = URL(string: preferencePath) {
        if #available(iOS 10.0, *) {
            UIApplication.shared.open(url, options: [:], completionHandler: nil)
        } else {
            UIApplication.shared.openURL(url)
        }
    } else {
        throw PreferenceExplorerError.notFound(preferencePath)
    }
}

使用UIApplication.openSettingsURLString

Swift 5.1更新

 override func viewDidAppear(_ animated: Bool) {
    let alertController = UIAlertController (title: "Title", message: "Go to Settings?", preferredStyle: .alert)

    let settingsAction = UIAlertAction(title: "Settings", style: .default) { (_) -> Void in

        guard let settingsUrl = URL(string: UIApplication.openSettingsURLString) else {
            return
        }

        if UIApplication.shared.canOpenURL(settingsUrl) {
            UIApplication.shared.open(settingsUrl, completionHandler: { (success) in
                print("Settings opened: \(success)") // Prints true
            })
        }
    }
    alertController.addAction(settingsAction)
    let cancelAction = UIAlertAction(title: "Cancel", style: .default, handler: nil)
    alertController.addAction(cancelAction)

    present(alertController, animated: true, completion: nil)
}

斯威夫特4.2

override func viewDidAppear(_ animated: Bool) {
    let alertController = UIAlertController (title: "Title", message: "Go to Settings?", preferredStyle: .alert)

    let settingsAction = UIAlertAction(title: "Settings", style: .default) { (_) -> Void in

        guard let settingsUrl = URL(string: UIApplicationOpenSettingsURLString) else {
            return
        }

        if UIApplication.shared.canOpenURL(settingsUrl) {
            UIApplication.shared.open(settingsUrl, completionHandler: { (success) in
                print("Settings opened: \(success)") // Prints true
            })
        }
    }
    alertController.addAction(settingsAction)
    let cancelAction = UIAlertAction(title: "Cancel", style: .default, handler: nil)
    alertController.addAction(cancelAction)

    present(alertController, animated: true, completion: nil)
}

App-Prefs:root=Privacy&path=LOCATION为我获得一般位置设置工作。注:仅在设备上有效。

我看过这行代码

UIApplication.sharedApplication() .openURL(NSURL(string:"prefs:root=General")!)

是不工作，它没有为我在ios10/ Xcode 8，只是一个小的代码差异，请替换这个

UIApplication.sharedApplication().openURL(NSURL(string:"App-Prefs:root=General")!)

Swift3

UIApplication.shared.openURL(URL(string:"prefs:root=General")!)

替换为

UIApplication.shared.openURL(URL(string:"App-Prefs:root=General")!)

希望能有所帮助。 欢呼。

如上所述@niravdesai说App-prefs。 我发现App-Prefs:适用于iOS 9、10和11。设备测试。 where as prefs:仅适用于iOS 9。

如果这是你想要的，这可能会占用你应用程序的特定设置。

UIApplication.shared.openURL(URL(string: UIApplicationOpenSettingsURLString)!)
