CLLocationmanager 在约 30 秒后抛出

Question

@起初我以为它没有开火，但看到this

所以我等待，现在我得到了未处理的异常：MonoTouch.Foundation.You_Should_Not_Call_base_In_This_Method：抛出了“MonoTouch.Foundation.You_Should_Not_Call_base_In_This_Method”类型的异常。在失败的处理程序中。

我已经定义了一个 CLLocationManager，这里是 FinishedLaunching & CLLocationManagerDelegate

public override bool FinishedLaunching (UIApplication app, NSDictionary options)
            {
                // If you have defined a view, add it here:
                // window.AddSubview (navigationController.View);

                _locationManager = new CLLocationManager();
                _locationManager.Delegate = new LocationManagerDelegate(this);
                _locationManager.StartUpdatingLocation();

                window.MakeKeyAndVisible ();


                return true;
            }




private class LocationManagerDelegate : CLLocationManagerDelegate
        {
            private AppDelegate _appd;
            public LocationManagerDelegate(AppDelegate appd)
            {
               _appd = appd;
                 Console.WriteLine("Delegate created");
            }
            public override void UpdatedLocation(CLLocationManager manager
                                                    , CLLocation newLocation, CLLocation oldLocation)
            {
                Console.WriteLine("Lat: " + newLocation.Coordinate.Latitude.ToString());


            }
              public override void Failed (CLLocationManager manager, NSError error)
            {
                //_appd.labelInfo.Text = "Failed to find location";
                Console.WriteLine("Failed to find location");
                base.Failed (manager, error);
            }
        }

我正在使用最新的 monodevelop、monotouch、xcode 和 iphone SDK，几天前刚刚安装了一个 coupla。有什么建议吗？

问候

例外是说您不应该在覆盖的“失败”方法中调用 base.Failed。
