Question

I have setup in storyboard a navigation controller and a tableview controller. There is a search bar in the tableview. I get a reference to the navigation controller using self.navigationcontroller. I use

[self.navigationController setNavigationBarHidden:YES animated:animated];

To hide the navigation bar in the subsequent view which is displayed. This works fine when selecting a cell in the tableview without using the searchbar. However, if I use the searchbar to display specific cells in the table view and if I select a cell from that table, then apparently I lose the reference to the navigation controller because although the above code is executed, the navigation bar is still displayed in the follwing view.

我该怎么把导航器藏起来?

Answer 1

这就是我发现的东西:导航BarHidden 属性显然被重置,因为当搜索栏离开视图时,它会再次发送导航栏到视图上。我不知道我是否确切理解正在发生的事情,但我认为这行代码会消失,解决了问题:

 self.searchDisplayController.active=NO;

Answer 2

为什么你不对以下的查看控制器执行那条代码线?

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [self.navigationController setNavigationBarHidden:YES animated:animated];
}
