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个按钮添加到UINavigationBar？
2个按钮应该对齐在UINavigationBar的右侧。

我知道如何添加一个按钮，但如何处理两个？

Answer 1

您可以创建一个UIView并在该视图中添加两个按钮。 并添加的UIView作为右键:)

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

self.navigationItem.rightBarButtonItem = rightItem; 

Answer 2

我posted code（见下文）两个按钮添加到的导航栏的右侧。您可以设置barStyle = -1而不是继承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

您可以使用一个工具栏为自定义视图初始化一个栏按钮。

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]; 

会看到这样的：

注：这个答案是过时的iOS 6或更高版本

Answer 4

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]; 

Answer 5

万一有人来这里，像我，寻找一个MonoTouch的答案，看看没有比NavigationItem.RightBarButtonItems阵列进一步。

Answer 6

您不必添加两个按钮。你只需要添加

UIBarButtonSystemItemFlexibleSpace 

不

UIBarButtonSystemItemFixedSpace 

和一个按钮，所以，这将是在右侧。

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 7

与iOS 5+是那么容易，因为：

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 8

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

在SWIFT

：

（假设你有一个导航控制器）在根控制器使用此代码：

左： ..

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

权：

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 

}

这里是我当前的项目工作示例：

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];

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

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

Answer 13

在SWIFT，您可以添加以下代码来设置两个按钮右侧（或左侧）：

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

Answer 14

SWIFT

您可以在swift这样做

 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 15

Prakash响应也适用于界面构建器。

将在UINavigationItem一个UIView，那么你可以把几个UIButton因为这UIView的孩子，并创建一个层次，像这样：

设置UIView的背景色来清除，并添加一些垂直居中按钮和固定水平位置的限制。这是我与零线的代码得到的结果：

Answer 16

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) 
    }

这里是斯威夫特4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){ 

    }
