URL Scheme "Open Settings" ios
提问by MaappeaL
I know this question has been asked so many times. The answers say that this is not available in Xcode > 5.x. but I saw some apps that can use this(Go to Settings)(iOS7). Is there any way to do this? Is it available in Xcode 6? Facebook can detect both cellular data and wifi.
我知道这个问题已经被问过很多次了。答案说这在 Xcode > 5.x 中不可用。但我看到一些可以使用它的应用程序（转到设置）（iOS7）。有没有办法做到这一点？它在 Xcode 6 中可用吗？Facebook可以检测蜂窝数据和 wifi。

As of iOS 8, it's possible to launch the Settings app that directly opens your Privacy app section in this way:

In Swift:
在斯威夫特：
if let settingsURL = NSURL(string: UIApplicationOpenSettingsURLString) {
UIApplication.sharedApplication().openURL(settingsURL)
}
In Swift 3.0:
在 Swift 3.0 中：

UIApplication.shared.openURL(settingsURL as URL)
}

This is not possible anymore in iOS 11, we can just open Settings. Here a Swift 4 code snippet:
这在 iOS 11 中不再可能，我们可以打开设置。这是一个 Swift 4 代码片段：
if let url = URL(string:UIApplicationOpenSettingsURLString) {
if UIApplication.shared.canOpenURL(url) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
}
}

}

Alerts on your screenshots are system alerts. The first occurs when app wants to use internet and have a blocked cellular data for application (and Wifi is not connected). The second occurs when an application wants to use location services, and you have turned off wifi. It is not possible control the display of these alerts.
屏幕截图上的警报是系统警报。第一种发生在应用程序想要使用互联网并阻止应用程序的蜂窝数据（并且未连接 Wifi）时。第二种情况发生在应用程序想要使用定位服务而您已关闭 wifi 时。 无法控制这些警报的显示。
In iOS 8 (Xcode 6) is the ability to open the settings directly from the application. Please read this topics: How to open Settings programmatically like in Facebook app?
在 iOS 8 (Xcode 6) 中，可以直接从应用程序打开设置。请阅读以下主题： 如何像在 Facebook 应用中一样以编程方式打开设置？
