Dismissing iPad UIPopoverController when BarButtonItem is pushed while it's open

Question

Using a split view on the iPad, I have the following code:

- (void) splitViewController:(UISplitViewController *)svc willHideViewController:(UIViewController         


        

Answer 1

If you are using the default UISplitViewController setup, then the navigation bar button that is created displays a popover of your RootViewController.

If you want to make sure you don't have multiple pop-ups on at once, you can simply dismiss pop-ups whenever your RootViewController will appear. Here's code I used to solve this problem:

- (void) viewWillAppear:(BOOL)animated {
  if ([self.popover isPopOverVisible]) {
    [self.popover dismissPopoverAnimated:YES];
  }
  [super viewWillAppear:YES];
}
