一段时间以来，我一直在努力解决导航栏项目的奇怪行为。我在导航栏上进行了分段控制（请看下图）

在此处输入图像描述

其中 List 按钮使用 UISearchDisplayController 推送表视图控制器。要显示表视图控制器，我使用如下代码：

if (uiSegmentedControl.selectedSegmentIndex == 1 )
{
    DetailsTableVewController* detailsViewController = [[DetailsTableVewController alloc] 
                                                         initWithList:list]; 
    [self.navigationController pushViewController:detailsViewController animated:YES];
    [detailsViewController release];
}

然后要返回，我使用以下代码：

[self.navigationController popViewControllerAnimated:YES];

虽然当 UISearchDisplayController 处于活动或非活动状态时我使用上面的代码返回到上一个控制器，但我有不同的导航行为酒吧物品。当 UISearchDisplayController 处于活动状态时，所有项都会从导航栏中消失

有人知道为什么吗它发生了吗？提前致谢。

I have been struggling for some time with the strange behavior of navigation bar items. I have segmented control on the navigation bar (take a look at the image below)

enter image description here

where List button pushes table view controller with UISearchDisplayController. To show table view controller I use the code as it follows:

if (uiSegmentedControl.selectedSegmentIndex == 1 )
{
    DetailsTableVewController* detailsViewController = [[DetailsTableVewController alloc] 
                                                         initWithList:list]; 
    [self.navigationController pushViewController:detailsViewController animated:YES];
    [detailsViewController release];
}

Then to return back I use the following code:

[self.navigationController popViewControllerAnimated:YES];

Although I use the code above to go back to the previous controller when UISearchDisplayController is either active or inactive I have different behavior of the navigation bar items. When UISearchDisplayController is active ALL items disappear from the navigation bar

Does anybody know why it happens?
Thanks in advance.
