Removing the rightBarButtonItem from moreNavigationController of UITabBarController

问题

I have added tabBar in my app and remove the rightBarButtonItem with the code:

UITableView *moreTableView = (UITableView *)tabController.moreNavigationController.topViewController.view;
    tabController.moreNavigationController.navigationBar.topItem.rightBarButtonItem = nil;

Now, when I navigate to other screen and click More button of tabBar, rightBarButtonItem appears again. If I uses back navigation button it doesn't appear and works fine. However, when I tap More button from tabBar it appears again.

回答1:

I used

tabController.customizableViewControllers = nil;

and it worked fine :)

回答2:

You should call navigationItem.rightBarButtonItem = nil in each viewControllers viewDidLoad where you want to get rid of it.

Otherwhise could you show more code of your implementation?
