    saveAndCloseViewController.navigationItem.title = @"Save or Discard";
    UIBarButtonItem *cancel = [[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStylePlain target:self action:@selector(cancelAction:)];          
    saveAndCloseViewController.navigationItem.rightBarButtonItem = cancel;
    [cancel release];
    UINavigationController *navControl = [[UINavigationController alloc] initWithRootViewController:saveAndCloseViewController];

    saveAndClosePopupView = [[UIPopoverController alloc] initWithContentViewController:navControl];
    saveAndClosePopupView.delegate = self;
    saveAndClosePopupView.popoverContentSize = CGSizeMake(312, 160);
    saveAndCloseViewController.view.contentMode = UIViewContentModeScaleAspectFill;
    [saveAndClosePopupView presentPopoverFromRect:[saveAndClose bounds] inView:saveAndClose permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

    [navControl release];

}

-(void)saveProjectClick:(id)sender{
        if (saveProject.tag == tagSave) {

        WGNameProjectViewController *nameProjectViewController = [[WGNameProjectViewController alloc] initWithNibName:nil  bundle:nil];
        [self.navigationController pushViewController:nameProjectViewController animated:YES];
        nameProjectViewController.navigationItem.title = @"Name Project";
        [nameProjectViewController release];
        nameProjectViewController = nil;

    }
}

You just need to add something like:

self.preferredContentSize = <view size>

to the viewWillAppear: method in each of your view controllers that are displayed in the popover.
