The latest version of Allen for Umbraco has now hit the Apple App store, we have managed to add some nice improvements to this version that include:
  • Storing location and direction information when photos are taken within the App
  • Embedding EXIF data into the images when they are upload
  • Background Uploading
  • Pull to refresh the media tree

Location and Direction

By default when the camera is used within an application the location and direction that the camera is pointing is not stored within the image meta data. We have now added full support so that this data is now added. We have added a setting which allows you to prevent this data from being uploaded to your website if you do not want the location data to be sent you can turn it off within Allen,

Note: Please don't forget that location services do need to be turned on to allow the app to access the images in the phone's asset library.

We have had quite a few ideas from users already for using this location data, including logging free parking in Denmark to geo-tagging holiday photos and linking the photos to Google street view.

Embedding EXIF data

We now embed all the meta data available on the iPhone into the image when it is uploaded to your server, this allows you to pull the data out and use it within your site. Have a look at Cultiv's Photo Meta Data package for great example code that allows you to automatically pull this data out and populate properties on your Umbraco media item.

We slightly modified the source code of this package to allow the package to always extract the image data, as the default package requires a property to allow the data to be extracted, it's an easy change, if you get stuck add a comment to this post.

Background Uploading

If you try to upload multiple images and need to start doing something else on your phone, you can now click the home button and the application will continue to upload your images in the background. As soon as it has finished you will receive a standard Apple notification.

Pull to Refresh

Our final enhancement has been to add "Pull to refresh" to the media trees, just pull the tree downwards with your finger and it will refresh, this is useful if you are adding items to your media tree while testing your site with Allen for Umbraco.

Future enhancements.. your ideas?
