Discussion
This method checks if the asset pack is currently downloaded. If it isn’t, then it schedules it to be downloaded and calls the block with nil for the block’s error parameter when the download completes. It’s guaranteed that the requested asset pack will be available locally once the block is called with nil for its error parameter. If a non-nil value is provided to the block’s error parameter, then the asset pack is not guaranteed to be available locally. You can optionally monitor download progress by attaching a delegate object to delegate.
