如何在导航栏右侧添加多个 UIBarButtonItem？

Question

我想在 UINavigationBar 的右侧有多个 UIBarButtonItem。我怎样才能做到这一点？

下面显示了我正在尝试的示例 - 您会注意到右上角有多个按钮。

Answer 1

-(void)viewDidLoad{

    UIBarButtonItem *anotherButton1 = [[UIBarButtonItem alloc] initWithTitle:@"Button_1" style:UIBarButtonItemStylePlain target:self action:@selector(button_1:)];

    UIBarButtonItem *anotherButton2 = [[UIBarButtonItem alloc] initWithTitle:@"Button_" style:UIBarButtonItemStylePlain target:self action:@selector(button_2:)];

    self.navigationItem.rightBarButtonItems=@[anotherButton1,anotherButton2];
}

Answer 2

在swift中使用这个：

override func viewDidLoad() {
  super.viewDidLoad()

  let editImage    = UIImage(named: "plus")!
  let searchImage  = UIImage(named: "search")!

  let editButton   = UIBarButtonItem(image: editImage,  style: .Plain, target: self, action: "didTapEditButton:")
  let searchButton = UIBarButtonItem(image: searchImage,  style: .Plain, target: self, action: "didTapSearchButton:")

  navigationItem.rightBarButtonItems = [editButton, searchButton]
}

像这样写动作函数：

func didTapEditButton(sender: AnyObject){
    ...
}

func didTapSearchButton(sender: AnyObject){
    ...
}

Swift 4 & 5

    override func viewDidLoad() {
        super.viewDidLoad()
        let editImage    = UIImage(named: "edit")!
        let searchImage  = UIImage(named: "search")!

        let editButton   = UIBarButtonItem(image: editImage,  style: .plain, target: self, action: #selector(didTapEditButton(sender:)))
        let searchButton = UIBarButtonItem(image: searchImage,  style: .plain, target: self, action: #selector(didTapSearchButton(sender:)))

        navigationItem.rightBarButtonItems = [editButton, searchButton]
    }

    @objc func didTapEditButton(sender: AnyObject){

    }

    @objc func didTapSearchButton(sender: AnyObject){

    }

Answer 3

我认为以上都行不通

试试这个

var burgerItem = UIBarButtonItem(image: UIImage(named:"categories"), style: .Plain, target: self, action: "categories")
        var weatherItem = UIBarButtonItem(title: "Weather", style: .Plain, target: self, action: "weather")


        burgerItem.tintColor = UIColor.whiteColor()
        weatherItem.tintColor = UIColor.whiteColor()

        navigationItem.setRightBarButtonItems([burgerItem,weatherItem], animated: true)

你必须使用 navigationItem.setRightBarButtonItems 并且要小心。 navigationItem 必须是视图控制器。

class testViewController:UIViewController {

ovverride func viewDidLoad() {
    self.navigationItem.setRightBarButtonItems(...

}

}

这可能对您有帮助 objective-c,

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {

    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.navigationItem.title = @"Title";
        UIBarButtonItem *logOutButton = [[UIBarButtonItem alloc] initWithTitle:@"Logout" style:UIBarButtonItemStylePlain target:self action:@selector(ButtonClickedAtIndex1:)];
        [logOutButton setTintColor:[UIColor blackColor]];
        logOutButton.tag = 1;

        UIBarButtonItem *syncBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Sync" style:UIBarButtonItemStylePlain target:self action:@selector(ButtonClickedAtIndex1:)];
        [syncBarButtonItem setTintColor:[UIColor blackColor]];
        syncBarButtonItem.tag = 2;

        self.navigationItem.leftBarButtonItem = logOutButton;
        self.navigationItem.rightBarButtonItem = syncBarButtonItem;

       float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];

       if (systemVersion >= 7.0) {
           self.edgesForExtendedLayout = UIRectEdgeNone;
           self.navigationController.navigationBar.translucent = NO;
       }
    }
    return self;
}

Answer 5

在Swift3中你可以使用：

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]

Answer 6

只需添加此代码：

self.navigationItem.leftBarButtonItem = nil

let button = UIButton(type: .custom)
button.setImage(UIImage (named: "ChatTab"), for: .normal)
button.frame = CGRect(x: 0.0, y: 0.0, width: 35.0, height: 35.0)
//button.addTarget(target, action: nil, for: .touchUpInside)
let barButtonItem = UIBarButtonItem(customView: button)

let button2 = UIButton(type: .custom)
button2.setImage(UIImage (named: "ActivityTab"), for: .normal)
button2.frame = CGRect(x: 0.0, y: 0.0, width: 35.0, height: 35.0)
//button.addTarget(target, action: nil, for: .touchUpInside)

let barButtonItem2 = UIBarButtonItem(customView: button2)
self.navigationItem.rightBarButtonItems = [barButtonItem, barButtonItem2]

这是结果：

使用 navigationItem 的 rightBarButtonItems，它采用 UIBarButton 的数组。 Appledoc

let share = UIBarButtonItem(barButtonSystemItem: .action, target: self, action: #selector(shareTapped))
let add = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(addTapped))
navigationItem.rightBarButtonItems = [add, share]

Answer 8

和Swift4

let editImage       = UIImage(named: "toolbar_edit")!
let favoriteImage   = UIImage(named: "toolbar_fav_solid")!

let editButton      = UIBarButtonItem(image: editImage,  style: .plain, target: self, action: #selector(didTapEditButton))
let favoriteButton  = UIBarButtonItem(image: favoriteImage,  style: .plain, target: self, action: #selector(didTapFavoriteButton))

navigationItem.rightBarButtonItems = [editButton, favoriteButton]

这些按钮的点击操作

@objc func didTapEditButton(sender: AnyObject) {
    print("edit")
}

@objc func didTapFavoriteButton(sender: AnyObject) {
    print("favorite")
}

Answer 9

对于具有新更新的 Xamarin iOS，就像：

UIBarButtonItem Button1 = new UIBarButtonItem(UIImage.FromBundle("Image1"), UIBarButtonItemStyle.Plain,YourEventHandler);
UIBarButtonItem Button2 = new UIBarButtonItem(UIImage.FromBundle("Image1"), UIBarButtonItemStyle.Plain,YourEventHandler);

NavigationItem.SetRightBarButtonItems(new[]{ Button1, Button2 }, true);

Answer 10

我不知道以前是否不可能使用 Interface Builder 解决方案，但至少在最近的更新 (Xcode 11.0) 中，可以将两个 UI Bar Buttons 拖入右栏按钮 space。然后可以像往常一样将两个出口和动作拖到代码中。

由于 OP 没有要求没有 IB 的解决方案，我认为这也可以作为答案。

Answer 11

接受的答案以及少数答案是绝对正确的，但在我的情况下 none 它们有效。

原因：我的视图控制器继承自 UIViewController，我必须在右侧设置添加到购物车按钮和搜索按钮。我所有的视图控制器都是 UITabbarController 的一部分。

    let editImage = UIImage(named: "OrdersTabIcon")
    let searchImage = UIImage(named: "OrdersTabIcon")
    let editButton = UIBarButtonItem(image: editImage, style: .plain, target: self, action: #selector(iconTapped))
    let searchButton = UIBarButtonItem(image: searchImage, style: .plain, target: self, action: #selector(iconTapped))

而不是使用

 self.navigationItem.setRightBarButtonItems([editButton, searchButton], animated: true)

使用这个 .

self.navigationController?.navigationBar.topItem?.setRightBarButtonItems([editButton, searchButton], animated: true)
