Öffnen Sie die App "Einstellungen" von einer anderen App programmgesteuert auf dem iPhone

Gute Nachricht :

Können Sie öffnen Sie die Einstellungen-apps programmatisch wie hier (funktioniert nur aus iOS8 ab).

Wenn Sie mit Swift 3.0:

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

Wenn Sie mit Objective-C:

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

Für die anderen niedrigeren Versionen (weniger als iOS8) ist nicht möglich, programmgesteuert öffnen Sie die app "Einstellungen".

Öffnen Sie Einstellungen-apps programmatisch ist nur möglich, von iOS 8. So verwenden Sie folgenden code,...

if([CLLocationManager locationServicesEnabled]&&
   [CLLocationManager authorizationStatus] != kCLAuthorizationStatusDenied)
{
  //...Location service is enabled
}
else
{
    if([[[UIDevice currentDevice] systemVersion] floatValue] < 8.0)
    {
       UIAlertView* curr1=[[UIAlertView alloc] initWithTitle:@"This app does not have access to Location service" message:@"You can enable access in Settings->Privacy->Location->Location Services" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
      [curr1 show];
    }
    else
    {
       UIAlertView* curr2=[[UIAlertView alloc] initWithTitle:@"This app does not have access to Location service" message:@"You can enable access in Settings->Privacy->Location->Location Services" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:@"Settings", nil];
       curr2.tag=121;
       [curr2 show];
    }
}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
   if (alertView.tag == 121 && buttonIndex == 1)
 {
  //code for opening settings app in iOS 8
   [[UIApplication sharedApplication] openURL:[NSURL  URLWithString:UIApplicationOpenSettingsURLString]];
 }
}

Hier ist ein Swift2-version, die für mich gearbeitet, einschließlich eine Warnung weist den Benutzer, was zu tun ist, wenn die Einstellungen öffnet.

func initLocationManager() {
    locationManager = CLLocationManager()
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.requestAlwaysAuthorization()


//If there isn't a Lat/Lon then we need to see if we have access to location services
//We are going to ask for permission to use location if the user hasn't allowed it yet.
let status = CLLocationManager.authorizationStatus()
if(status == CLAuthorizationStatus.NotDetermined || status == CLAuthorizationStatus.Denied)  {

    //println(locationManager)

    // check that locationManager is even avaiable.  If so, then ask permission to use it
    if locationManager != nil {
        locationManager.requestAlwaysAuthorization()

        //open the settings to allow the user to select if they want to allow for location settings.
        let alert = UIAlertController(title: "I Can't find you.", message: "To let my App figure out where you are on the map click 'Find Me' and change your location to 'Always' and come back to MyMobi.", preferredStyle: UIAlertControllerStyle.Alert)
        alert.addAction(UIAlertAction(title: "No Thanks", style: UIAlertActionStyle.Default, handler:nil))
        alert.addAction(UIAlertAction(title: "Find Me", style: UIAlertActionStyle.Default, handler: {
            (alert: UIAlertAction!) in
            UIApplication.sharedApplication().openURL(NSURL(string: UIApplicationOpenSettingsURLString)!)
        }))
        self.presentViewController(alert, animated: true, completion: nil)


    }
}
}
