- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
    UINavigationItem *ipcNavBarTopItem;

    // add done button to right side of nav bar
    UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:@"Photos"
                                                                   style:UIBarButtonItemStylePlain 
                                                                  target:self 
                                                                  action:@selector(saveImages:)];

    UINavigationBar *bar = navigationController.navigationBar;
    [bar setHidden:NO];
    ipcNavBarTopItem = bar.topItem;
    ipcNavBarTopItem.title = @"Photos";
    ipcNavBarTopItem.rightBarButtonItem = doneButton;
}

这解决了问题的问题.
