For anyone who is unclear on how to implement the accepted answer, here is a code example to more clearly explain how to "<a href="https://stackoverflow.com/questions/9832518/ios-pass-data-across-child-navigation-controller#answer-9832549">have a pointer to the navigation controller</a>." The following code passes an NSString from AAA (AAAViewController) to CCC (CCCViewController) with an identifier named "ToCCC" for the segue. 1) Create a pointer to <code>foo</code> in <code>CCCViewController.h</code>. <pre><code>// CCCViewController.h #import <UIKit/UIKit.h> @interface CCCViewController : UITableViewController @property (strong, nonatomic) NSString *foo; @end </code></pre> 2) In <code>AAAViewController.m</code>, create a pointer to CCCViewController (via the navigation controller) and then set <code>foo</code>. <pre><code>// AAAViewController.m #import "AAAViewController.h" #import "CCCViewController.h" // Note the import statement for CCC. @implementation AAAViewController - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if ([segue.identifier isEqualToString: @"ToCCC"]) { CCCViewController *ccc = [[segue.destinationViewController viewControllers] objectAtIndex: 0]; ccc.foo = @"A string passed from AAA"; } } @end </code></pre> 3) Do something with <code>foo</code> in <code>CCCViewController.m</code> (e.g. log it to the console). <pre><code>// CCCViewController.m #import "CCCViewController.h" @implementation CCCViewController - (void)viewDidLoad { [super viewDidLoad]; // Log foo to the console. NSLog(@"%@", _foo); } @end </code></pre>

Guidance

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.
