Body
When you add the UINavigationController via the Nib it actually creates an instance of a UINavigationController inside the nib file with a default RootViewController set (of type UIViewController) and with a default title of RootViewController. When you load the nib, this object is being created as part of loading the nib (i.e when you initialise DocumentsViewController) - so the navigationControllerDocuments outlet is already initialised as a UINavigationController with the default ViewController already set on it. What I think is happening is when you call 'initWithRootViewController' - you are calling this on an already initialised object - so it is running the initialisation code again - pushing the second view controller (the DocumentRootViewController) onto the stack, but the default one that was created in the nib is already there. What you should probably do is forget about creating one in the nib and initialise the whole thing programatically. i.e. where you do: <pre><code>[navigationControllerDocuments initWithRootViewController:rootViewController]; </code></pre> I suggest that you do an alloc and init instead: <pre><code>[[navigationControllerDocuments alloc] initWithRootViewController:rootViewController]; </code></pre> Since you are doing this you really don't need to have the navigation controller added to the nib so if this works you should remove it from the nib since you are replacing it with this one in code.

1. COYour reasoning was right and I managed to find the correct solution thanks to your answer. I just edited the initialization line as it displayed a Warning in Xcode with the one that made my project work correctly, and marked the answer as the correct one.

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.
