    <p>I'm building an iPhone app that, among other things, allows the user to take and store photographs associated with locations. I am currently using the ALAssetLibrary to allow the photographs to be stored in Photos and be accessible outside the app (on a computer for instance via the built-in mechanisms). There is not a lot of technical content out there for working with the ALAssetLibrary but from what there is I have managed to cobble together a working version of this. I have had to resort to storing a dictionary of photo URLS in my app and manually detecting if the photo still exists when displaying lists of them because there does not seem to be a way to add custom metadata to an ALAsset.</p> <p>What I would really like to do is add two custom metadata fields to each asset to provide it with a title and a custom id value that I can use to filter on when enumerating the asset library.</p> <p>As a secondary task, I'd like the user to be able to update the title metadata.</p> <p>Can it be done? At this point, I really don't think it can because the API really doesn't seem to provide the necessary methods to get/set custom metadata. I'm hoping against all odds that there is some other aspect to the AssetLibrary framework that I have not yet discovered.</p> <p>At a minimum, if someone can authoritatively say "NO" then at least others might find this breadcrumb on their own trail of hope and change tack more quickly!</p> <p>And, having 0 reputation I can't tag it with AssetLibrary :( wow, this day is just going downhill.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
