    <p>I am triggering a background fetch by using the <code>content-available</code> flag on a push notification. I have the <code>fetch</code> and <code>remote-notification</code> <code>UIBackgroundModes</code> enabled.</p> <p>Here is the implementation I am using in my AppDelegate.m:</p> <pre><code>- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler { NSLog(@"Remote Notification Recieved"); UILocalNotification *notification = [[UILocalNotification alloc] init]; notification.alertBody = @"Looks like i got a notification - fetch thingy"; [application presentLocalNotificationNow:notification]; completionHandler(UIBackgroundFetchResultNewData); } </code></pre> <p><strong>When the app is running in the background, it works fine.</strong> (The notification is received and the app triggered the "looks like i got a notification" local notification, as the code above should do). </p> <p>However, <strong>when the app is not running</strong> and a push notification is received with the <code>content-available</code> flag, <strong>the app is not launched</strong> and the <code>didRecieveRemoteNotification</code> delegate method is never called. </p> <p>The WWDC Video <em>Whats New With Multitasking</em> (#204 from WWDC 2013) shows this: <img src="https://i.imgur.com/9OHaGys.png" alt="enter image description here"></p> <p>It says that the application is "launched into background" when a push notification is received with the <code>content-available</code> flag.</p> <p>Why is my app not launching into the background?</p> <p><strong>So the real question is:</strong></p> <p>Will iOS perform background tasks after the user has force-quit the app?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
