    <p>(This is both question and answer since it took quite a bit of digging to find the real answer.)</p> <p>Symptom: <code>viewWillAppear</code>, <code>viewDidAppear</code> were not being called in my UIViewController. </p> <p>Cause: Embedding a <code>UINavigationController</code> or <code>UITabBarController</code> (my case) in a <code>UIViewController</code> somehow interrupts with the calling of these methods.</p> <p>Solution: Call them manually in the <code>UIViewController</code> that contains the aforementioned <code>UINavigationController</code> / <code>UITabBarController</code>.</p> <p>For example (assuming <code>projectNavigationController</code> is your <code>UINavigationController</code>):</p> <pre> -(void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [projectNavigationController viewWillAppear:animated]; } -(void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [projectNavigationController viewWillDisappear:animated]; } -(void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [projectNavigationController viewDidAppear:animated]; } -(void)viewDidDisappear:(BOOL)animated { [super viewDidDisappear:animated]; [projectNavigationController viewDidDisappear:animated]; } </pre> <p>In my case I had an inner <code>UITabBarController</code> and I called the methods accordingly and all was solved.</p> <p>(Attribution on the solution: <a href="http://davidebenini.it/2009/01/03/viewwillappear-not-being-called-inside-a-uinavigationcontroller/" rel="noreferrer">http://davidebenini.it/2009/01/03/viewwillappear-not-being-called-inside-a-uinavigationcontroller/</a>)</p>

    1. COjust because I'm curious...: why would you wrap a tab bar controller into another viewcontroller? :) in most cases, they are the root of the view (controller) hierarchy...

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.

SQuiL has stopped working due to an internal error.

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