    As mentioned by Karan Dua this is now possible in iOS8 using UIApplicationOpenSettingsURLString see Apple's Documentation.

    Example:

    Swift 4.2

    UIApplication.shared.open(URL(string: UIApplication.openSettingsURLString)!)
    

    In Swift 3:

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

    In Swift 2:

    UIApplication.sharedApplication().openURL(NSURL(string:UIApplicationOpenSettingsURLString)!)
    

    In Objective-C

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
    

    Prior to iOS 8:

    You can not. As you said this has been covered many times and that pop up asking you to turn on location services is supplied by Apple and not by the App itself. That is why it is able to the open the settings application.
