title: PHImageManager maximum target size not working in Xamarin iOS
body: <p>I have the following code in my GMImagePickerController in FinishedPicking Event. </p>
  
  <pre><code>picker.FinishedPickingAssets += (s, args) =&gt;
          {
              PHImageManager imageManager = new PHImageManager();
              PHImageRequestOptions imageOptions = new PHImageRequestOptions();
              imageOptions.DeliveryMode = PHImageRequestOptionsDeliveryMode.HighQualityFormat;
              imageOptions.ResizeMode = PHImageRequestOptionsResizeMode.Exact;
              foreach (var asset in args.Assets)
              {
                  imageManager.RequestImageForAsset(asset,
                    new CGSize(asset.PixelWidth,asset.PixelHeight),
                    PHImageContentMode.Default,
                    imageOptions,
                    (image1, info) =&gt;
                    {
                        if(count&lt;1)
                        {
                            CommonFunction.AttachPhotoiOS(image1, eventRecordID, cp, "NormalImage");
                            count++;
                        }
                        //CallCommonFunctionAttachPhotoiOS(image1, eventRecordID);
                    });
                  break;
              }
          };
  </code></pre>
  
  <p>As you can see I have already set the CGSize to the asset width and height, but still, when I debug and mouse over the image1 which is the retrieved image, the width and height is always 90 x 120 but not the original size of the asset. I have tried many ways and many images, the width and height seems like fixed forever. Which part has been done wrong? How can I get the original size of the image from it? </p>
