An array of
NSValueobjects, each containing a
CMTime, specifying the asset times at which an image is requested.
A block called when an image request is complete.
This method uses an efficient “batch mode” to get images in time order.
The client receives exactly one handler callback for each requested time in
requested. Changes to the generator’s properties (snap behavior, maximum size, and so on) do not affect pending asynchronous image generation requests.
