xCode - 工具欄按鈕項目標籤更改

在我的項目（「Xcode 4.3.2 - 單一視圖應用程序」）中，我手動添加了一個帶有按鈕項目的工具欄，我需要以編程方式更新按鈕標籤。我該怎麼做？你可以幫我嗎？xCode - 工具欄按鈕項目標籤更改

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; 

- (IBAction) changeLabel:(id)sender; 

@end

ViewController.m

- (IBAction) changeLabel:(id)sender{ 

    //code for updating label 

}

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

- (IBAction) changeLabel:(id)sender{ 

barButton.title = @"test"; 

}

一定要設置BarButtonItem爲引用奧特萊斯「barButton」
