iphone - How do I make the rightBarButtonItem STAY when a view controller is pushed on?

Question

When I push a view onto my view controller

- (void)tableView:(UITableView *)tableView
        didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
  AnotherViewController *anotherViewController = 
      [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil];
  [self.navigationController pushViewController:anotherViewController animated:YES];
}

the RIGHT BUTTON ITEM of the navigationController DISAPPEARS.

Is there a way to make the self.navigationController.rightBarButtonItem STAY THERE like in the "Notes" application that comes with the iPhone?

Answer 1

我不相信你可以不使用无证类。但是，如果您将rightBarButtonItem属性设置为看起来相同的项目，则应该不会有太大差异。

Answer 2

你可以这样做

self.anotherViewController.navigationItem.rightBarButtonItem = self.parentViewController.navigationItem.rightBarButtonItem;

在你推送了 ChildViewController 之后
