设置导航控件的标题

Question

我将基于窗口的应用程序转换为基于导航的应用程序，但我无法设置导航栏的标题。

controller = [[bookDisplayViewController alloc] initAndCreateView]; 

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

Answer 1

是否有可能为你把

self.navigationItem.title = @"YourName"; 

于另一视角的viewDidLoad中？我会尝试这种方式，看看它是否有效。

Answer 2

您必须在UIViewController中设置标题。试试这个：在UINavigationItem

controller.navigationItem.title=@"Application"; 

逸岸苹果文档的“标题”属性指出：

 
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.
