How to get "Purchase Date" or "Date Added" from MPMediaItems in iPod Library

Since users are downloading new songs to their iPod Music library from the iTunes Store, I would like to programmatically list these songs in a table. Is it possible to get "Date Added" or "Date Purchased" from MPMediaItemCollection? I see there are property keys like play counter and last date. I know the data exists because it can be viewed in iTunes, but I cannot find it. Any suggestions on where to find this or how to get it?

As you can see in Apple's documentation for MPMediaItem http://developer.apple.com/library/ios/#documentation/mediaplayer/reference/MPMediaItem_ClassReference/Reference/Reference.html#//apple_ref/occ/cl/MPMediaItem you get access to all properties via enumerateValuesForProperties:usingBlock:

or valueForProperty:

, but no property exists for date or purchase information.

This does not mean that the data is not stored somewhere (it certainly is): it means that you cannot access this information through public APIs, possibly for privacy concerns.



I don't know at all if there is a way to get this information through some private API calls, but if it exists, you cannot use it for AppStore apps because it will cause a failure in the browsing process.

As of iOS 10, we have access to two dateAdded properties.

Note. iOS 10 is still in beta (4) at the time of writing, so things could change.

As a Date object:

MPMediaItem.dateAdded


and as a line:

MPMediaItemPropertyDateAdded
