 * your content.
 *
 * In addition to making code changes, the following items must be
 * added to your app's Info.plist file:
 *
 * To enable newsstand:
 *   <key>UINewsstandApp</key>
 *   <true/>
 *
 * To enable background downloads:
 *   <key>UIBackgroundModes</key>
 *   <array>
 *     <string>newsstand-content</string>
 *   </array>
 *
 * You must also register for Newsstand pushes by adding 
 * UIRemoteNotificationTypeNewsstandContentAvailability to your 
 * registerForRemoteNotificationTypes: call.
