    <p>I have a custom UIActivity that I use in order to create a Contact to the device's AddressBook. In this UIActivity, I create an ABNewPersonViewController, put it inside a UINavigationController and return it in UIActivity's</p> <pre><code>- (UIViewController *)activityViewController </code></pre> <p>The problem is that on the iPad I get a crash due to a reference to a released UINavigationController. Messages are of type:</p> <pre><code>*** -[UINavigationController _viewControllerForSupportedInterfaceOrientations]: message sent to deallocated instance 0xa6f1660 </code></pre> <p>Also after my controller is dismissed, the iPad does not autorotate the view when the interface changes orientation.</p> <p>The code I use is the following:</p> <p><strong>In UIActivity</strong> </p> <pre><code>- (void)prepareWithActivityItems:(NSArray *)activityItems { // Prepare the AB View Controller ABRecordRef aContact = ABPersonCreate(); CFErrorRef error = NULL; ABRecordSetValue(aContact, kABPersonKindProperty, kABPersonKindOrganization, &amp;error); ABRecordSetValue(aContact, kABPersonOrganizationProperty, @"Apple Inc.", &amp;error); ABMultiValueRef phone = ABMultiValueCreateMutable(kABMultiStringPropertyType); ABMultiValueAddValueAndLabel(phone, @"+1 2345 784513", kABWorkLabel, NULL); ABRecordSetValue(aContact, kABPersonPhoneProperty, phone, &amp;error); CFRelease(phone); self.newContactVC.title = @"New company"; self.newContactVC.displayedPerson = aContact; [self.navigation setViewControllers:[NSArray arrayWithObject:self.newContactVC]]; CFRelease(aContact); } - (UIViewController *)activityViewController { return self.navigation; } // Dismisses the new-person view controller. - (void)newPersonViewController:(ABNewPersonViewController *)newPersonViewController didCompleteWithNewPerson:(ABRecordRef)person { [self activityDidFinish:YES]; } </code></pre> <p><strong>In the ViewController</strong> that calls this UIActivity</p> <pre><code>- (IBAction)showActionsSheet:(id)sender { AddToAddressBookActivity *abActivity = [[AddToAddressBookActivity alloc] init]; UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:nil applicationActivities:[NSArray arrayWithObject:abActivity]]; activityVC.excludedActivityTypes = @[UIActivityTypeAssignToContact, UIActivityTypeSaveToCameraRoll]; if (!self.popover || ![self.popover isPopoverVisible]) { self.popover = [[UIPopoverController alloc] initWithContentViewController:activityVC]; [self.popover setDelegate:self]; self.popover.passthroughViews = nil; [self.popover presentPopoverFromRect:self.showASBtn.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; } } </code></pre> <p>Any help would be greatly appreciated.</p> <p><em>Link to a demo project:</em> <a href="http://ge.tt/23MeOYq/v/0?c" rel="nofollow">http://ge.tt/23MeOYq/v/0?c</a></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).
