RÁPIDO

Puedes hacerlo rápido como este

        var editImg   : UIImage = UIImage(named: "plus")!
        var searchImg : UIImage = UIImage(named: "search")!

        var editBtn : UIBarButtonItem = UIBarButtonItem(image: editImg,  style: UIBarButtonItemStyle.Plain, target: self, action: Selector("editBtnPressed:"))

        var searchBtn : UIBarButtonItem = UIBarButtonItem(image: searchImg,  style: UIBarButtonItemStyle.Plain, target: self, action: Selector ("searchBtnPressed:"))

        var buttons : NSArray = [editBtn, searchBtn]

        self.navigationItem.rightBarButtonItems = buttons

        func editBtnPressed(sender: AnyObject){

        }

        func searchBtnPressed(sender: AnyObject){

        }

Answer 2

Aquí está el ejemplo de trabajo de mi proyecto actual:

UIButton *homeBtn =  [UIButton buttonWithType:UIButtonTypeCustom];
[homeBtn setImage:[UIImage imageNamed:@"home-icon"] forState:UIControlStateNormal];
//[homeBtn addTarget:self action:@selector(home) forControlEvents:UIControlEventTouchUpInside];
[homeBtn setFrame:CGRectMake(0, 0, 32, 32)];

UIButton *settingsBtn =  [UIButton buttonWithType:UIButtonTypeCustom];
[settingsBtn setImage:[UIImage imageNamed:@"settings-icon"] forState:UIControlStateNormal];
//[settingsBtn addTarget:self action:@selector(settings) forControlEvents:UIControlEventTouchUpInside];
[settingsBtn setFrame:CGRectMake(44, 0, 32, 32)];

UIView *rightBarButtonItems = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 76, 32)];
[rightBarButtonItems addSubview:homeBtn];
[rightBarButtonItems addSubview:settingsBtn];

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:rightBarButtonItems];

Answer 3

Con iOS 5+ es tan fácil como:

UIBarButtonItem *btnShare = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@selector(share)];
UIBarButtonItem *btnRefresh = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(refresh)];
[self.navigationItem setRightBarButtonItems:[NSArray arrayWithObjects:btnShare, btnRefresh, nil]];

Answer 4

Desde iOS 5 en adelante, es fácil de lograr. UINavigationItem tiene la capacidad de tener múltiples botones en el lado izquierdo y derecho de la barra.

http://developer.apple.com/library/ios/#documentation/UIKit/Reference/UINavigationItem_Class/Reference/UINavigationItem.html#//apple_ref/occ/instm/UINavigationItem/setRightBarButtonItems:animated :

Answer 5

En SWIFT, puede agregar este código para configurar dos botones en el lado derecho (o izquierdo):

self.navigationItem.rightBarButtonItems = [UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Action, target: self, action: "barButtonItemClicked"), UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Search, target: self, action: "barButtonItemClicked")]

Answer 6

En caso de que alguien venga aquí, como yo, en busca de una respuesta MonoTouch, no busque más allá de la matriz NavigationItem.RightBarButtonItems .

Answer 7

La respuesta de Prakash también funciona en el constructor de interfaces.

Arrastre una UIView en el UINavigationItem , luego puede poner varios UIButton como UIButton de esta UIView y crear una jerarquía como esta:

Establezca el color de fondo de UIView para borrar y agregue algunas restricciones para centrar verticalmente los botones y fijar la posición horizontal. Aquí está el resultado que obtuve con cero línea de código:

Answer 8

No tienes que agregar dos botones. Solo necesitas agregar

UIBarButtonSystemItemFlexibleSpace 

no

UIBarButtonSystemItemFixedSpace

y un botón, para que esté en el lado derecho.

Me gusta esto:

UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 40)];
toolbar.barStyle = UIBarStyleBlackTranslucent;

UIBarButtonItem *spaceButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];

UIBarButtonItem *infoButtonItem1 = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(empresaTextFieldDone)];    

toolbar.items = [NSArray arrayWithObjects: spaceButton, infoButtonItem1, nil];   

Answer 9

Puede crear un UIView y agregar dos botones en esa vista. Y agregue ese UIView como el botón derecho :)

UIView* rightItem = [UIView alloc] initWithFrame:frame];
//Create UIButton1 b1
//Create UIButton2 b2
[rightItem addSubview:b1];
[rightItem addSubview:b2];

self.navigationItem.rightBarButtonItem = rightItem;

Answer 10

Puede usar un botón de barra inicializado con una barra de herramientas como una vista personalizada.

UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 103.0f, 44.01f)];
NSArray* buttons = [NSArray arrayWithObjects:self.editButtonItem, someOtherButton, nil];
[toolbar setItems:buttons animated:NO];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:toolbar];

Daría algo como esto:

Nota: esta respuesta es obsoleta para iOS 6 o posterior

Answer 11

en SWIFT:

(supongamos que tiene un controlador de navegación) en Root Controller use este código:

izquierda: ..

    let leftBtn =  UIBarButtonItem(title: "Do It", style: UIBarButtonItemStyle.Plain,
        target: self, action: "doIt:")
    leftBtn.tag=100
    self.navigationItem.leftBarButtonItem = leftBtn

derecho:

    let rightView = UIView(frame:  CGRectMake(0, 0, 100, 30))
    rightView.backgroundColor = UIColor.redColor()

    let btn1 = UIButton(frame: CGRectMake(0,0,60, 20))
    btn1.setTitle("R1", forState: UIControlState.Normal)
    btn1.tag=101
    btn1.addTarget(self, action: "doIt:", forControlEvents: UIControlEvents.TouchUpInside)
    rightView.addSubview(btn1)

    let btn2 = UIButton(frame: CGRectMake(30,0,60, 20))
    btn2.setTitle("R2", forState: UIControlState.Normal)
    btn2.tag=102
    btn2.addTarget(self, action: "doIt:", forControlEvents: UIControlEvents.TouchUpInside)
    rightView.addSubview(btn2)


    let rightBtn = UIBarButtonItem(customView: rightView)
    self.navigationItem.rightBarButtonItem = rightBtn;

..

dónde:

 func doIt(sender: AnyObject!){
    let tag = sender.tag

}

Answer 12

Publiqué el código (ver a continuación) para agregar dos botones a la derecha de la barra de navegación. Puede establecer barStyle = -1 lugar de subclasificar UIToolbar .

UIToolbar *tools = [[UIToolbar alloc]
                    initWithFrame:CGRectMake(0.0f, 0.0f, 103.0f, 44.01f)]; // 44.01 shifts it up 1px for some reason
tools.clearsContextBeforeDrawing = NO;
tools.clipsToBounds = NO;
tools.tintColor = [UIColor colorWithWhite:0.305f alpha:0.0f]; // closest I could get by eye to black, translucent style.
                                                              // anyone know how to get it perfect?
tools.barStyle = -1; // clear background
NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:3];

// Create a standard refresh button.
UIBarButtonItem *bi = [[UIBarButtonItem alloc]
    initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(refresh:)];
[buttons addObject:bi];
[bi release];

// Create a spacer.
bi = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
bi.width = 12.0f;
[buttons addObject:bi];
[bi release];

// Add profile button.
bi = [[UIBarButtonItem alloc] initWithTitle:@"Profile" style:UIBarButtonItemStylePlain target:self action:@selector(goToProfile)];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
[bi release];

// Add buttons to toolbar and toolbar to nav bar.
[tools setItems:buttons animated:NO];
[buttons release];
UIBarButtonItem *twoButtons = [[UIBarButtonItem alloc] initWithCustomView:tools];
[tools release];
self.navigationItem.rightBarButtonItem = twoButtons;
[twoButtons release];

Answer 13

Aquí está el código de Swift 4:

    let editImage   = UIImage(named: "plus")!
    let searchImage = UIImage(named: "search")!
    let editButton   = UIBarButtonItem(image: editImage,  style: .plain, target: self, action:#selector(didTapEditButton))
    let searchButton = UIBarButtonItem(image: searchImage,  style: .plain, target: self, action:#selector(didTapSearchButton))
    navigationItem.rightBarButtonItems = [editButton, searchButton]


 @objc func didTapEditButton(sender: AnyObject){

  }

 @objc func didTapSearchButton(sender: AnyObject){

  }

Answer 14

Rápido:

override func viewDidLoad() {
    super.viewDidLoad()

    // Additional bar button items
    let button1 = UIBarButtonItem(image: UIImage(named: "image1.png"), style: .Plain, target: self, action: "methodA")
    let button2 = UIBarButtonItem(image: UIImage(named: "image2.png"), style: .Plain, target: self, action: "methodB")
    let button3 = UIBarButtonItem(image: UIImage(named: "image3.png"), style: .Plain, target: self, action: "methodC")

    navigationItem.leftItemsSupplementBackButton = true
    navigationItem.setLeftBarButtonItem(button1, animated: true)
    navigationItem.setRightBarButtonItems([button2, button3], animated: true)

Métodos para botones:

func methodA() {
    performSegueWithIdentifier("segA", sender: nil)
}

func methodB() {
    performSegueWithIdentifier("segB", sender: nil)
}

func methodC() {
    performSegueWithIdentifier("segC", sender: nil)
}

UIView* buttonsView= [[UIView alloc] initWithFrame:CGRectMake(10, 6, 84, 32)];
buttonsView.backgroundColor=[UIColor clearColor];

btn_back = [UIButton buttonWithType:UIButtonTypeCustom];
[btn_back addTarget:self action:@selector(backButtonClick) 
forControlEvents:UIControlEventTouchUpInside];
btn_back.frame = CGRectMake(0, 0, 32, 32);
btn_back.backgroundColor=[UIColor colorWithPatternImage:[UIImage imageNamed:@"close.png"]];

btn_help = [UIButton buttonWithType:UIButtonTypeCustom];
[btn_help addTarget:self action:@selector(helpButtonClick) 
 forControlEvents:UIControlEventTouchUpInside];
btn_help.frame = CGRectMake(42, 0, 32, 32);
btn_help.backgroundColor=[UIColor colorWithPatternImage:[UIImage imageNamed:@"info.png"]];

[buttonsView addSubview:btn_back];
[buttonsView addSubview:btn_help];

segmentItem = [[UIBarButtonItem alloc] initWithCustomView:buttonsView];
self.navigationItem.rightBarButtonItem = segmentItem;
