迁移到统一MediaPickerController后出现Xamarin移动应用编程接口错误

Question

我只是使用迁移工具将我的Xamarin iOS应用程序迁移到Xamarin Unified。下面的代码运行正常，应用程序在迁移之前没有任何错误或警告。在迁移之后，我得到了以下错误: Error-1 PresentViewController不接受MediaPickerController对象作为参数。错误-2\f25 mediaPickerController -2没有方法-2\f25 DismissViewController -2\f6

        protected void TakePicture()
    {
        MediaPickerController mediaPickerController = mediaPicker.GetTakePhotoUI(new StoreCameraMediaOptions
        {
            Name =  this.PictureName + ".jpg",
            DefaultCamera = CameraDevice.Rear
        });
        if (!mediaPicker.IsCameraAvailable)
        {
            ShowUnsupported();
        }


//Error-1
        PresentViewController(mediaPickerController, true, null);
        try
        {
            mediaPickerController.GetResultAsync().ContinueWith(t =>
            {
                BTProgressHUD.Show("Processing");
                // Dismiss the UI yourself
//Error-2
                mediaPickerController.DismissViewController(true, () =>
                {
                    if (t.IsCanceled || t.IsFaulted)
                    {
                        BTProgressHUD.Dismiss();
                        return;
                    }
                    MediaFile file = t.Result;
                    FinishedPickingMedia(file);
                    BTProgressHUD.Dismiss();
                });


            }, TaskScheduler.FromCurrentSynchronizationContext());
        }
        catch (Exception ex)
        {
            Insights.Report(ex, ReportSeverity.Error);
        }
    }

从这里的https://components.xamarin.com/view/xamarin.mobile下载最新的统一动态链接库，并引用lib/ios- Xamarin.Mobile /Xamarin.Mobile.dll而不是旧的动态链接库。这将修复错误。
