title: Loading image from "My Photo Stream" using UIImagePicker results URL and PHAsset on iOS8
body: <p>I am updated an app from ios7 to ios8 and struggling to get UIImagePicker working to load a picture from the "My Photo Stream" category of photos.  The UIImagePicker implementation is standard and I retrieve the URL of the selected photo with:</p>
  
  <pre><code>NSURL *url = [info objectForKey:@"UIImagePickerControllerReferenceURL"];
  </code></pre>
  
  <p>I then use the new IOS8 APIs for loading this photo:</p>
  
  <pre><code>PHFetchResult *result = [PHAsset fetchAssetsWithALAssetURLs:@[url] options:nil];
  </code></pre>
  
  <p>This fails to work. The result.count is zero and no image is found.  The URL has an different UUID than if I select the photo from "Moments" or "Camera Roll" but looks well formed.  (phone is running 8.1):</p>
  
  <p>url NSURL * @"assets-library://asset/asset.JPG?id=4522DBD1-862C-42BE-AF7C-0D6C76CA7590&amp;ext=JPG"</p>
  
  <p>Anyone have some code to load photos from "My Photo Stream" or a way to disable it for the UIImagePicker display?</p>
  
  <p>Using the older ALAssetsLibrary assetForURL API also fails to load these images.</p>
