Question

In my project (“Xcode 4.3.2 – Single View Application”), I have manually added a ToolBar with a button item, i need to update the button label programatically.
How can i do this? Could you please help me?

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

}

Answer 1

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

- (IBAction) changeLabel:(id)sender{

barButton.title = @"test";

}

Be sure to set the BarButtonItem as Referencing Outlet “barButton”
