In my implementation, I will change the title of the page after triggering some method

//In viewdidload of my view controller which resides in a navigation controller
-(void)viewDidLoad
{
    self.title = @"Title A";
}


-(void)changeTitle
{
    self.title = @"Title B";
}

In the above example, after I trigger the 'changeTitle' method, I do not see my viewcontroller's title change immediately. In fact I need to push another viewcontroller onto the stack and subsequently press 'back' before I see the change to "title B".

Is there any way to refresh the navbar's title at the point where I change title?

我猜你正在寻找：

UrNavController.navigationBar.topItem.title = @"bkjasdkahsdflkjadf";

您可以在按下按钮后重置它。

您还可以为该主题分配一些其他对象，例如段控件或 uilabel。

Objective-C

如果要刷新以前的 viewController 的标题，请使用

self.parent?.title = "Some Title"
