A key indicating that the app was launched to process newly downloaded Newsstand assets.
- iOS 5.0+
The value of this key is an array of string identifiers that identify the
NKAsset objects corresponding to the assets. Although you can use the identifiers for cross-checking purposes, you should obtain the definitive array of
NKAsset objects (representing asset downloads in progress or in error) through the
downloading property of the
NKLibrary object representing the Newsstand app’s library.
