这是设置:

1. 我有一个UITableViewController,带有一个调用模态视图的导航按钮:

    - (void)viewDidLoad
    {

        self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@selector(showAbout)];
    }

    - (void)showAbout
    {
        AboutViewController *abv = [[AboutViewController alloc] init];
        abv.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
