設置導航控件的標題

Question

我將基於窗口的應用程序轉換爲基於導航的應用程序，但我無法設置導航欄的標題。

controller = [[bookDisplayViewController alloc] initAndCreateView]; 

UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:controller]; 
nav.title=@"Application"; 
[window addSubview:nav.view]; 

Answer 1

是否有可能爲你把

self.navigationItem.title = @"YourName"; 

於另一視角的viewDidLoad中？我會嘗試這種方式，看看它是否有效。

Answer 2

您必須在UIViewController中設置標題。試試這個：在UINavigationItem

controller.navigationItem.title=@"Application"; 

逸岸蘋果文檔的「標題」屬性指出：

 
title 
A localized string that represents the view that this controller manages. 

@property(nonatomic, copy) NSString *title 
Discussion 
Subclasses should set the title to a human-readable string that represents the view to the user. If the receiver is a navigation controller, the default value is the top view controller’s title. 

Availability 
Available in iOS 2.0 and later.
