ajouter plus de deux boutons sur la barre de navigation

Je suis en train d'essayer mais ça ne fonctionne pas.

-(void)viewDidLoad
{
    //create a toolbar where we can place some buttons
    UIToolbar* toolbar = [[UIToolbar alloc]
                    initWithFrame:CGRectMake(0, 0, 100, 45)];
    [toolbar setBarStyle: UIBarStyleBlackOpaque];

    //create an array for the buttons
    NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:3];

    //create a standard save button
    UIBarButtonItem *saveButton = [[UIBarButtonItem alloc]
        initWithBarButtonSystemItem:UIBarButtonSystemItemSave
        target:self
        action:@selector(saveAction:)];
    saveButton.style = UIBarButtonItemStyleBordered;
    [buttons addObject:saveButton];
    [saveButton release];

    //create a spacer between the buttons
    UIBarButtonItem *spacer = [[UIBarButtonItem alloc]
        initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace
        target:nil
        action:nil];
    [buttons addObject:spacer];
    [spacer release];

    //create a standard delete button with the trash icon
    UIBarButtonItem *deleteButton = [[UIBarButtonItem alloc]
        initWithBarButtonSystemItem:UIBarButtonSystemItemTrash
        target:self
        action:@selector(deleteAction:)];
    deleteButton.style = UIBarButtonItemStyleBordered;
    [buttons addObject:deleteButton];
    [deleteButton release];

    //put the buttons in the toolbar and release them
    [toolbar setItems:buttons animated:NO];
    [buttons release];

    //place the toolbar into the navigation bar
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]
            initWithCustomView:toolbar];
    [toolbar release];
}

Comment puis-je résoudre ce problème?

    Essayer cet extrait de code

    Et Dans AppDelegate.h fichier vous déclarez cette

    UINavigationController *navigationController;

    Et AppDelegate.m fichier

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
//Override point for customization after application launch.
//Add the view controller's view to the window and display.
navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
[self.window addSubview:navigationController.view];
[self.window makeKeyAndVisible];
return YES;
}

    avec iOS 5, vous pouvez ajouter d'autres boutons 

    self.navigationItem.leftBarButtonItems = [NSArray arrayWithObjects:uibarbuttonInstance1, uibarbuttonInstance2, nil];

    de même pour les boutons de droite

    self.navigationItem.rightBarButtonItems = [NSArray arrayWithObjects:uibarbuttonInstance1, uibarbuttonInstance2, nil];

    Je pense que je suis en train de donner u mon code cela va résoudre ur problème ...

    -(void) initializeNavigationalBar {
self.navigationItem.title  = @"What Ever");
self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:(57/255) green:(57/255) blue:(57/255) alpha:1];
UIBarButtonItem *optionBtn; 
optionBtn = [[UIBarButtonItem alloc] 
initWithImage:[UIImage imageNamed:@"image1.png"]
style:UIBarButtonItemStylePlain 
target:self 
action:@selector(LoadOption:)];
self.navigationItem.leftBarButtonItem = optionBtn;
//create a toolbar to have two buttons in the right
UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 60, 44.01)];
//create the array to hold the buttons, which then gets added to the toolbar
NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:2];
UIBarButtonItem *rightBtn = [[UIBarButtonItem alloc] 
initWithImage:[UIImage imageNamed:@"image2.png"]
style:UIBarButtonItemStylePlain target:self 
action:@selector(decrement:)];
[buttons addObject:rightBtn];
[previousBtn release];
UIBarButtonItem *leftBtn = [[UIBarButtonItem alloc] 
initWithImage:[UIImage imageNamed:@"image3.png"]
style:UIBarButtonItemStylePlain target:self 
action:@selector(increment:)];
[buttons addObject:leftBtn];
[nextBtn release];
[tools setItems:buttons animated:NO];
tools.tintColor = [UIColor colorWithRed:(57/255) green:(57/255) blue:(57/255) alpha:1];
[buttons release];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:tools];
[tools release];

    }
