Как добавить 2 кнопки в UINavigationBarбез XIB?
Две кнопки должны быть выровнены по правой стороне UINavigationBar.

Я знаю, как добавить одну кнопку, но как насчет двух?

С iOS 5+ это так же просто, как:

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]];

Я разместил код (см. Ниже), чтобы добавить две кнопки справа от панели навигации. Вы можете установить barStyle = -1вместо подкласса 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];

Вы можете использовать кнопку на панели, инициализированную с помощью панели инструментов, в качестве настраиваемого представления.

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];

Дала бы что-то вроде этого:

Примечание: этот ответ устарел для iOS 6 или новее.

Вот рабочий пример из моего текущего проекта:

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];

UINavigationBar *navBarView = [[UINavigationBar alloc] initWithFrame: CGRectMake(0.0f, 0.0f, 320.0f, 42.0f)];
    navBarView.tintColor= [UIColor colorWithRed:90.0/255.0f green:53.0/255.0f blue:45.0/255.0f alpha:1.0];

    UIBarButtonItem *left=[[UIBarButtonItem alloc]initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:self action:@selector(backView)];
    UIBarButtonItem *right=[[UIBarButtonItem alloc]initWithTitle:@"Save" style:UIBarButtonItemStylePlain target:self action:@selector(SaveImage)];
    UIBarButtonItem *Add=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(AddComment:)];

    UINavigationItem *navigationItem = [[UINavigationItem alloc] init];
    navigationItem.leftBarButtonItem = left;
    NSMutableArray *buttonArray=[[NSMutableArray alloc]initWithCapacity:2];
    [buttonArray addObject:right];
    [buttonArray addObject:Add];
    navigationItem.rightBarButtonItems = buttonArray;
    [navBarView pushNavigationItem:navigationItem animated:NO];
[self.view addSubView:navBarView];

Swift:

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)

Способы для кнопок:

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

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

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

SWIFT

Вы можете сделать в стрижа , как это

        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){
        
        }

Вы можете создать UIView и добавить в него две кнопки. И добавьте этот UIView как правую кнопку :)

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

self.navigationItem.rightBarButtonItem = rightItem;

Ответ Prakash также работает в конструкторе интерфейсов.

Перетащите a UIViewв UINavigationItem, затем вы можете поместить несколько в UIButtonкачестве дочерних для этого UIViewи создать такую ​​иерархию:

Установите цвет фона UIViewкнопки на очистку и добавьте некоторые ограничения для вертикального центрирования кнопок и фиксации горизонтального положения. Вот результат, который я получил с нулевой строкой кода:

В SWIFT вы можете добавить этот код для настройки двух кнопок справа (или слева):

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

Начиная с iOS 5, этого легко добиться. UINavigationItem может иметь несколько кнопок слева и справа от панели.

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

Вот код 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){

  }

Вам не нужно добавлять две кнопки. Вам просто нужно добавить

UIBarButtonSystemItemFlexibleSpace 

не

UIBarButtonSystemItemFixedSpace

и кнопку, чтобы она была справа.

Как это:

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];   

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;

Если кто-то приходит сюда, как я, в поисках ответа MonoTouch, не ищите ничего, кроме NavigationItem.RightBarButtonItemsмассива.

в SWIFT:

(предположим, у вас есть навигационный контроллер) в корневом контроллере используйте этот код:

осталось: ..

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

верно:

    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;

..

где:

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

}

    func makeCustomNavigationBar () {

        // Create the navigation bar
        let navigationBar = UINavigationBar(frame: CGRectMake(0, 20, self.view.frame.size.width, 44)) // Offset by 20 pixels vertically to take the status bar into account
        navigationBar.backgroundColor = UIColor.init(hexString: "E43037")
        navigationBar.delegate = self;

        navigationBar.setBackgroundImage(UIImage(), forBarMetrics: .Default)
        navigationBar.shadowImage = UIImage()
        navigationBar.translucent = true

        // Create a navigation item with a title
        let navigationItem = UINavigationItem()
        navigationBar.tintColor = UIColor.whiteColor()

        navigationItem.title = "Forgot Password"
        navigationBar.titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()]

        // Create left and right button for navigation item
        let leftButton = UIBarButtonItem(title: "", style: UIBarButtonItemStyle.Plain, target: self, action: nil)
        leftButton.action = "returnToLoginView"

        let backbuttonImageView =  UIImageView(frame: CGRectMake(0, 0, 30, 30))
        backbuttonImageView.image = UIImage(named: "nav-arrow-left")
        leftButton.image = backbuttonImageView.image
        navigationItem.leftBarButtonItem = leftButton


let rightButton = UIBarButtonItem(title: "Right", style: UIBarButtonItemStyle.Plain, target: self, action: nil)
        rightButton.action = "navigateToDashBoardView"

        let rightButtonImageView =  UIImageView(frame: CGRectMake(0, 0, 30, 30))
        rightButtonImageView.image = UIImage(named: "nav-arrow-left")
        rightButton.image = backbuttonImageView.image
        navigationItem.rightBarButtonItem = rightButton

        // Assign the navigation item to the navigation bar
        navigationBar.items = [navigationItem]

        // Make the navigation bar a subview of the current view controller
        self.view.addSubview(navigationBar)
    }
