    <p>this is a question we've all wondered about a number of times, and no one seems to have a good answer.</p> <p>How do apps like DataMan run on a regular basis in the background, indefinitely, and still get into the app store?</p> <p>The app allows a user to turn on "precise data tracking" and select a frequency at which the app updates it's data usage counters with zero user interaction - the intervals are once every minute, once every 10 minutes, and once every 20 minutes.</p> <p>Yes, I've read all the associated <a href="http://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/ManagingYourApplicationsFlow/ManagingYourApplicationsFlow.html#//apple_ref/doc/uid/TP40007072-CH4-SW3" rel="nofollow noreferrer">Apple Documentation on background processes</a> and implemented many of them successfully. I've also <a href="https://stackoverflow.com/questions/4656214/iphone-backgrounding-to-poll-for-events/4808049#4808049">explored the ins and outs of this old post</a>, but it's old enough now that many of those "loop holes" have been patched and the documented stuff works better anyway.</p> <p>While I've had great luck with registering my app as a VOIP app and requesting a keep-alive at certain intervals, it's not app-store-ok unless it's a VOIP app (DataMan isn't). Furthermore, registering for VOIP keep-alives doesn't actually exhibit the same behavior as DataMan...VOIP keep-alive calls come at somewhat-random intervals, or at least at the frequency you select without syncing up to clock time. DataMan actually falls in line with clock-mandated intervals and updates its data counters at the :10, :20, :30 minute marks, etc.</p> <p>Any ideas?</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.
