Opening app's notification settings in the settings app
提问by Matt
In the case that a user may accidentally declines to receive notifications and wants to turn notifications later, how can I use an NSURL to open the IOS Settings App to my app's notification page where they can select Allow Notifications?
如果用户可能不小心拒绝接收通知并想稍后打开通知，我该如何使用 NSURL 将 IOS 设置应用打开到我应用的通知页面，在那里他们可以选择允许通知？

For Swift 3, use UIApplicationOpenSettingsURLStringto go to settings for your app where it shows the Notifications status and "Cellular Data"
对于 Swift 3，用于UIApplicationOpenSettingsURLString转到您的应用程序的设置，其中显示通知状态和“蜂窝数据”
let settingsButton = NSLocalizedString("Settings", comment: "")
let cancelButton = NSLocalizedString("Cancel", comment: "")
let message = NSLocalizedString("Your need to give a permission from notification settings.", comment: "")
let goToSettingsAlert = UIAlertController(title: "", message: message, preferredStyle: UIAlertControllerStyle.alert)
goToSettingsAlert.addAction(UIAlertAction(title: settingsButton, style: .destructive, handler: { (action: UIAlertAction) in
DispatchQueue.main.async {
guard let settingsUrl = URL(string: UIApplicationOpenSettingsURLString) else {
return
}
if UIApplication.shared.canOpenURL(settingsUrl) {
if #available(iOS 10.0, *) {
UIApplication.shared.open(settingsUrl, completionHandler: { (success) in
print("Settings opened: \(success)") // Prints true
})
} else {
UIApplication.shared.openURL(settingsUrl as URL)
}
}
}
}))
logoutUserAlert.addAction(UIAlertAction(title: cancelButton, style: .cancel, handler: nil))

I found the answer to this question (albeit helpful) has a bit too much assumed logic. Here is a plain and simple Swift 5 implementation if anyone else stumbles upon this question:
我发现这个问题的答案（虽然有帮助）有一些假设的逻辑。如果其他人偶然发现这个问题，这里有一个简单明了的 Swift 5 实现：
if let bundleIdentifier = Bundle.main.bundleIdentifier, let appSettings = URL(string: UIApplication.openSettingsURLString + bundleIdentifier) {
if UIApplication.shared.canOpenURL(appSettings) {
UIApplication.shared.open(appSettings)
}
}

UPDATE:This will be rejected by Apple.
更新：这将被苹果拒绝。
To open notifications part of settings use this
要打开设置的通知部分，请使用此
UIApplication.shared.open(URL(string:"App-Prefs:root=NOTIFICATIONS_ID")!, options: [:], completionHandler: nil)
