Question

So I have a popover with a button in it. When that button is pushed, I want the popover to go away. It seems easy enough, but I can’t figure it out for the life of me. The code I use to show the popover is below:

    AddCategoryViewController* content = [[AddCategoryViewController alloc] init];
 UIPopoverController* aPopover = [[UIPopoverController alloc]
          initWithContentViewController:content];
 aPopover.delegate = self;
 [content release];

 // Store the popover in a custom property for later use.
 self.addCategoryPopover = aPopover;
 [aPopover release];
 [addCategoryPopover presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];

Within the addcategoryviewcontroller, I have:

    -(IBAction)saveAddCategory:(id)sender {
 if (rootViewController == nil)
  rootViewController = [[RootViewController alloc] init];

 [rootViewController.addCategoryPopover dismissPopoverAnimated:YES];
 [rootViewController dismissPopover];
}

Rootviewcontroller is where the popover is being created from. Unfortunately, neither of those methods work to dismiss it. any help?

You would be seeing a warning at this line.

 aPopover.delegate = self;

and if you would execute your code. The app would crash. Instead you need to do it like this.
