迁移到统一API后的错误消息

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);
    }
}

您需要将包含MediaPickerController的Xamarin组件更新为与Xamarin.iOS统一代码兼容的最新版本！

Xamarin.Mobile的最新版本是0.7.6。如果您使用的是较旧的项目，请仔细检查您的项目。
