Question

How do you dismiss a popover from within a navigation stack. I have a navigation controller as the root controller of the popover and 2 taes vies in the stack. So that the first table view pushes the second and the second should dismiss the popover. I could pass a reference from table to table of the popover though this seems wrong. What is the preferred way of dismissing a popover after navigated through different controllers?

In your appdelegate, add a new NSNotificationCenter observer:

[[NSNotificationCenter defaultCenter] addObserver:self 
                                         selector:@selector(hidePopover)
                                             name:@"hidePopover" 
                                           object:nil];

Once you have that setup, add a new method within the appdelegate like so:

-(void)hidePopover{
    [UIPopoverController dismissPopoverAnimated:YES];
}

This approach is great, because now you have things set up in such a way that you can close the popover from anywhere. You do this like so:

[[NSNotificationCenter defaultCenter] postNotificationName:@"hidePopover" 
                                                    object:nil];

Hope this solves your conundrum,
