Add a notification in main view's viewDidLoad

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

write function in Main view

-(void)dismissThePopover:(id)sender
{
     if ([popoverController isPopoverVisible]) {
            [popoverController dismissPopoverAnimated:YES];
        }
}

and finally post the notification from where u have to dismiss the popover controller, like

-(IBAction)cancelButtonPressed:(id)sender
{
    [[NSNotificationCenter defaultCenter] postNotificationName:@"dismissThePopover" object:nil];
}
