Use the Assets Library framework. Follow these steps:
Allocate and initialize an object of type
Provide two block objects to the
instance method of the Assets Library object. The first block will
retrieve all the groups associated with the type that we passed to
this method. The groups will be of type
ALAssetsGroup. The second block returns an
error in case of failure.

of each group object to enumerate the assets
available in each group. This method takes a single parameter, a
block that retrieves information on a single asset. The block that
