    <p>I am seeing this really weird issue with pushing/popping a UIViewController with custom buttons in the view. I confirmed it does not happen with other views I have like UIViewTableController, etc.. I have a function that calculates the navbar + status bar height, and then I offset my icons so their origin starts at CGMakeRect(0.0f, navbarheight+statusbarheight, ....) This looks great when I start the main screen on the phone (this view is initialized as the root view):</p> <p><a href="https://dl.dropboxusercontent.com/u/28315319/photo%20%282%29.PNG" rel="nofollow">https://dl.dropboxusercontent.com/u/28315319/photo%20%282%29.PNG</a></p> <p>Then, when I push a new view onto the navigation controller, I see this gap appear out of nowhere. This does NOT occur on the simulator, but does occur on the phone. Again, that top button is being placed as CGMakeRect(0.0f, navbarheight+statusbarheight, ....)</p> <p><a href="https://dl.dropboxusercontent.com/u/28315319/photo%20%283%29.PNG" rel="nofollow">https://dl.dropboxusercontent.com/u/28315319/photo%20%283%29.PNG</a></p> <p>Finally, when I pop that view, my original root view contains this gap.</p> <p><a href="https://dl.dropboxusercontent.com/u/28315319/photo%20%281%29.PNG" rel="nofollow">https://dl.dropboxusercontent.com/u/28315319/photo%20%281%29.PNG</a></p> <p>No clue what is causing this to happen on the real phone (iphone 4s + iphone 5) and not the simulators. If you need more info, let me know.</p> <p>UPDATE:</p> <p>As far as I can tell - this is a bug in the XCode simulator not taking into account the navigationbar height. I am no longer using the simulator and just distributing it to my phone.</p>

    2. COIt appears that the gap on the 3rd snapshot is equal to your navbar + statusbar height

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.
