Check user settings for push notification in Swift

Question

I have push notifications in my app. Whenever the app is launched, I would like to check whether the user has enabled push notification for my application.

I do it this

Answer 1

There is no way to change settings from the app. But you can lead user to application specific system settings using this code.

extension UIApplication {
    class func openAppSettings() {
        UIApplication.sharedApplication().openURL(NSURL(string: UIApplicationOpenSettingsURLString)!)
    }
}

Updated for Swift 3.0

extension UIApplication {
    class func openAppSettings() {
        UIApplication.shared.openURL(URL(string: UIApplicationOpenSettingsURLString)!)
    }
}
