如何在没有IB的情况下在右侧的UINavigationbar中添加2个按钮？

Question

如何在没有XIB的情况下将{2}按钮添加到UINavigationBar中？ 2个按钮应对齐UINavigationBar。

的右侧

我知道如何添加一个按钮，但两个按钮怎么样？

Answer 1

使用iOS 5+，它就像以下一样简单：

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 2

我posted code（见下文）在navigationBar右侧添加两个按钮。您可以设置barStyle = -1，而不是子类化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 3

您可以使用使用工具栏初始化的条形按钮作为自定义视图。

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];

会给出这样的东西：

Answer 4

以下是我当前项目的工作示例：

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 5

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];

<强>夫特：

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)

按钮的方法：

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

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

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

SWIFT

你可以像这样 swift

        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 8

您可以在该视图中创建UIView并添加两个按钮。 并将UIView添加为右键：）

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

self.navigationItem.rightBarButtonItem = rightItem;

Answer 9

Prakash响应也适用于界面构建器。

在UIView中拖动UINavigationItem，然后您可以将多个UIButton作为此UIView的子项，并创建一个层次结构，如下所示：

设置UIView的背景颜色以清除并添加一些约束以使按钮垂直居中并固定水平位置。这是我用零行代码得到的结果：

Answer 10

在SWIFT中，您可以添加此代码以在右侧（或左侧）设置两个按钮：

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

Answer 11

这是Swift 4代码：

    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 12

从iOS 5开始，很容易实现。 UINavigationItem能够在栏的左侧和右侧有多个按钮。

Answer 13

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;

Answer 14

您不必添加两个按钮。你只需要添加

UIBarButtonSystemItemFlexibleSpace 

不是

UIBarButtonSystemItemFixedSpace

和一个按钮，以便它在右侧。

像这样：

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 15

SWIFT中的

：

（假设您有一个导航控制器）在根控制器中使用此代码：

左： ..

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

右：

    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;

...

其中：

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

}

Answer 17

    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.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()]

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)
    }
