    <p>I released an iPhone/iPad app some weeks ago. From 15 reviews (worldwide) I got a dozen 1 star reviews from users saying the app does not work, they only get a blank screen. The other three are happy and it works for them.</p> <p>I tested the app on an iPad 1, an iPad 2, an iPhone 3GS and several iPhone 4s - it worked on every device flawlessly. And it passed the app store submission process, so it must have worked at Apple...</p> <p>The crash report in iTunes Connect is empty - the app obviously does not crash, it just hangs somewhere.</p> <p>Unfortunately there is no way to contact the users where it doesn't work :-(</p> <p>I know its really hard to help with that less information, but I don't know what to do when I can't replicate the problem on my side...</p> <p>So does anybody has any idea?</p> <p>If its a memory problem - shouldn't the app crash then?</p> <p>I use AVFoundation to play a movie and I know of some flaws since its a relatively new library - does somebody know of this problem (a blank screen) in relation with AVFoundation?</p> <p>It would be helpful as well if you could download the app (the name is "Hyperactive") and test if you get a blank screen. If so I would be glad to learn the exact device and the iOS version. I hope this is not missunderstood as spam, thats not what I intend...</p> <p>Thanks in advance,</p> <p>best regards,</p> <p>Walchy</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
