iphone - 无法设置 UITabBarController 的 moreNavigationController 的右键

我遇到了一个非常奇怪的问题，我可以设置 UITabBarController 的 moreNavigationController 的所有属性，但 rightBarButtonItem 属性除外。我猜这可能是因为一些与可定制的ViewControllers 属性相关的错误禁用了所有右栏按钮项。任何想法如何解决？

    UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] 
                                   initWithBarButtonSystemItem:UIBarButtonSystemItemDone 
                                   target:self 
                                   actionselector(popViewController)];

    self.customizableViewControllers = nil;
    self.moreNavigationController.navigationBar.barStyle = UIBarStyleBlack;
    self.moreNavigationController.topViewController.navigationItem.title = @"test"; //this works
    self.moreNavigationController.topViewController.navigationItem.leftBarButtonItem = doneButton; // this works
    self.moreNavigationController.topViewController.navigationItem.rightBarButtonItem = doneButton; // this doesn't

好的解决方案是使用 moreNavigationController 的委托(delegate)

- (void)navigationControllerUINavigationController *)navigationController willShowViewControllerUIViewController *) viewController animatedBOOL)animated {

viewController.navigationItem.rightBarButtonItem = doneButton;

}
