How to get videos with PHVideo from iCloud on Xamarin iOS?

Question

I implemented multimedia picker (for images and videos) with DependencyService on Xamarin.Forms app. I have a problem on iCloud videos. When I select video that is on icloud, I can't get it.

My implementation is:

async void FinishedPickingAssets(object sender, MultiAssetEventArgs args)
         {
             IList<MediaFile> results = new List<MediaFile>();
             TaskCompletionSource<IList<MediaFile>> tcs = new TaskCompletionSource<IList<MediaFile>>();
    
             try 
             { 
                 var options = new PHImageRequestOptions()
                 {
                     NetworkAccessAllowed = true
                 };
    
                 options.Synchronous = false;
                 options.ResizeMode = PHImageRequestOptionsResizeMode.Fast;
                 options.DeliveryMode = PHImageRequestOptionsDeliveryMode.HighQualityFormat;
                 bool completed = false;
                 for (var i = 0; i < args.Assets.Length; i++)
                 {
                     var asset = args.Assets[i];
    
                     string fileName = string.Empty;
                     if (UIDevice.CurrentDevice.CheckSystemVersion(9, 0))
                     {
                         fileName = PHAssetResource.GetAssetResources(asset).FirstOrDefault().OriginalFilename;
                         fileName = Path.GetFileNameWithoutExtension(fileName) + "(" + i.ToString() + ")" + Path.GetExtension(fileName);
                     }
    
                     switch (asset.MediaType)
                     {
                         case PHAssetMediaType.Video:
                         {
                                 var vOptions = new PHVideoRequestOptions();
                                 vOptions.NetworkAccessAllowed = true;
                                 vOptions.Version = PHVideoRequestOptionsVersion.Original;
                                 vOptions.DeliveryMode = PHVideoRequestOptionsDeliveryMode.Automatic;
                                 string videoUrl = "";
    
                                 PHImageManager.DefaultManager.RequestAvAsset(asset, vOptions, (avAsset, audioMix, vInfo) => 
                                 {
                                     DispatchQueue.MainQueue.DispatchAsync(() => {
    
                                         var error = vInfo.ObjectForKey(PHImageKeys.Error);
                                            
                                         if (avAsset != null)
                                         {
                                             videoUrl = ((AVFoundation.AVUrlAsset)avAsset).Url.Path;
                                         }
                                         var meFile = new MediaFile()
                                         {

                                         OnMediaPicked?.Invoke(this, meFile);
    
                                         if (args.Assets.Length == results.Count && !completed)
                                         {

             mediaPickTcs?.TrySetResult(await tcs.Task);
         }

When I try to select iCloud object, I get following error:

How can I take videos with multiple select from icloud?

Thank you in advance.

Answer 1

Firstly make sure that you had turn on iCloud Photos .

 1. Go to Settings > [your name] > iCloud.
 2. Tap Photos.
 3. If you need to, tap to turn on iCloud Photos.

Then check if the video and photo display in Photo App on your device .

For multiple selection and several customizations you could install the plugin GMImagePicker.Xamarin from nuget .
