xCode - 工具栏按钮项目标签更改

在我的项目（“Xcode 4.3.2 - 单一视图应用程序”）中，我手动添加了一个带有按钮项目的工具栏，我需要以编程方式更新按钮标签。我该怎么做？你可以帮我吗？xCode - 工具栏按钮项目标签更改

ViewController.h

#import <UIKit/UIKit.h> 

@interface ViewController : UIViewController <UIWebViewDelegate>{ 
    IBOutlet UIWebView *webDisplay; 
    IBOutlet UIToolbar *menuBar; //my toolBar 
} 
@property(nonatomic,retain) UIWebView *webDisplay; 
@property(nonatomic,retain) UIToolbar *menuBar;

@interface ViewController : UIViewController <UIWebViewDelegate>{ 
    IBOutlet UIWebView *webDisplay; 
    IBOutlet UIToolbar *menuBar; //my toolBar 
    IBOutlet UIBarButtonItem *barButton; 
} 
... 

- (IBAction) changeLabel:(id)sender{ 

barButton.title = @"test"; 

}

一定要设置BarButtonItem为引用奥特莱斯 “barButton”
