Apple Newsstand Download Complete Notification

Question

I have a newsstand application which provides the downloads through the NKNewsstandKit.

My Problem is that when i start downloading a asset & terminate the application, it downloads in the background perfectly. It also invoke the application in background mode. But i did not get the event connectionDidFinishDownloading:

Does anyone even have an idea, how i can get the event & process my assets.

Answer 1

If you start downloading while the app is running and then terminate the app you won't get any asset download delegate methods called (there is a launch option UIApplicationLaunchOptionsNewsstandDownloadsKey which I expected in this case but I've never seen this happen). The best solution is when the user starts the app, resume downloading each of the assets in [[NKLibrary sharedLibrary] downloadingAssets] and you should get a connectionDidFinishDownloading for each that has already downloaded. Be sure to do this in the didFinishLaunchingWithOptions method on the main thread or the assets will be deleted.
