UISplitViewController - Hide master slide-in view

Question

My app has a UICollectionViewController in its master view controller. When the device is on portrait orientation, the user can swipe the screen to reveal the master view.

When a collection cell is selected, the detail view is updated with new data. Now I'd like the master view to hide automatically at the same time. Is it possible?

Answer 1

Found the answer at the Apple Developers Forum

First make sure that the detail view controller has a reference to the popover view:

- (void)splitViewController:(UISplitViewController *)svc
    willHideViewController:(UIViewController *)aViewController
         withBarButtonItem:(UIBarButtonItem *)barButtonItem
      forPopoverController:(UIPopoverController *)pc {
    //Grab a reference to the popover
    self.popover = pc;
}

Then dismiss the popover when updating the detail view:

if (_popover != nil) {
    [_popover dismissPopoverAnimated:YES];
}

In the UICollectionViewController you can do

UISplitViewController *splitVC = (UISplitViewController *)self.parentViewController;
    splitVC.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryHidden;
