    <p>I have an iPad SplitViewController application in which I hide the left pane in both portrait and landscape modes. I need to show the left pane in its popover when a certain notification is received by the application. Despite experimenting with a number of different suggested solutions I am struggling to work out how to achieve this.</p> <p>I am using a MultipleMasterDetailManager implementation that includes the following code:</p> <pre><code>/* forward the message to the current detail view * all detail views must implement UISplitViewControllerDelegate */ -(void)splitViewController:(UISplitViewController *)svc willHideViewController:(UIViewController *)aViewController withBarButtonItem:(UIBarButtonItem *)barButtonItem forPopoverController:(UIPopoverController *)pc { self.masterBarButtonItem = barButtonItem; self.masterPopoverController = pc; barButtonItem.title = NSLocalizedString(@"Show Sidebar", @"Show Sidebar"); [self.currentDetailController.navigationItem setLeftBarButtonItem:self.masterBarButtonItem animated:YES]; } /* forward the message to the current detail view * all detail views must implement UISplitViewControllerDelegate */ -(void)splitViewController:(UISplitViewController *)svc willShowViewController:(UIViewController *)aViewController invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem { //if (![self.currentDetailController isKindOfClass:[SyncSourceDetailViewController class]]) //{ self.masterBarButtonItem = nil; self.masterPopoverController = nil; [self.currentDetailController.navigationItem setLeftBarButtonItem:nil animated:YES]; //} } </code></pre> <p>Similar methods exist in the detail view controllers themselves.</p> <p>The method that I'm calling when the notification is received is as follows:</p> <pre><code>- (void)navigateToLatest { [self navigateToDocumentsTab]; [[self dataLoader] navigateToLatest]; // populates data for the left table view UISplitViewController *splitViewController = (UISplitViewController *)self.window.rootViewController; UIView *view = [[[[[splitViewController viewControllers] objectAtIndex:1] viewControllers] objectAtIndex:0] view]; [self.masterDetailManager.masterPopoverController presentPopoverFromRect:CGRectMake(0, 0, 100, 100) inView:view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; } </code></pre> <p>This does not work. I've also tried using the presentPopoverFromBarButtonItem method but I cannot seem to locate the leftBarButtonItem in code.</p> <p>Maybe I am going about this completely the wrong way.</p>

    1. COThis view: `UIView *view = [[[[[splitViewController viewControllers] objectAtIndex:1] viewControllers] objectAtIndex:0] view];` is this really the parent view you want to use?

    2. CO@slf - you are correct, I have been continuing to work on this and I have determined that the view that I need is: self.masterDetailManager.currentDetailController.view. However this still does not work - I have a feeling it is to do with timing as the leftBarButtonItem for this view does not exist at this point in time, also willHideViewController in the masterDetailManager is called subsequent to my navigateToLatest method.

    3. CO@slf - I have been able to get showing of the left pane to work from a BarButtonItem using similar code so I know I am not too far away. Maybe I need to be delaying the call to show the left pane in some way.

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.
