Ios 导航栏右栏按钮项间距

我创建了一个 从情节提要中添加左栏按钮项，从代码中添加标题视图和三个右栏按钮项

代码如下：

override func viewDidLoad() {
    super.viewDidLoad()

    var screenWidth = UIScreen.mainScreen().bounds.width
    // custom title view
    var navBarWidth: CGFloat = self.navigationController!.navigationBar.frame.size.width
    let customTitleView = UIView(frame: CGRectMake(0, 0, navBarWidth, 44))
    titleLabel = UILabel(frame: CGRectMake(20, 0, navBarWidth, 40))
    titleLabel.text = conversationName
    if let titleFont = UIFont(name: "Roboto-Regular", size: 20) {
        titleLabel.font = titleFont
    }
    titleLabel.textColor = UIColor.whiteColor()

    customTitleView.addSubview(titleLabel)
    self.navigationItem.titleView = customTitleView

    // right bar buttons
    var searchImage = UIImage(named: "search")!
    var clipImage = UIImage(named: "clip")!
    var pencilImage = UIImage(named: "pencil")!

    var searchBtn = UIBarButtonItem(image: searchImage, style: UIBarButtonItemStyle.Plain, target: self, action: Selector("searchBtnPressed"))
    searchBtn.tintColor = UIColor.whiteColor()
    var clipBtn = UIBarButtonItem(image: clipImage, style: UIBarButtonItemStyle.Plain, target: self, action: Selector("clipBtnPressed"))
    clipBtn.tintColor = UIColor.whiteColor()
    var pencilBtn = UIBarButtonItem(image: pencilImage, style: UIBarButtonItemStyle.Plain, target: self, action: Selector("pencilBtnPressed"))
    pencilBtn.tintColor = UIColor.whiteColor()

    self.navigationItem.setRightBarButtonItems([pencilBtn, clipBtn, searchBtn], animated: false)
}

我的问题是，我想改变右按钮之间的间距，但我不知道如何改变

我试图在它们之间添加一个固定按钮，但它只是增加了现有的空间

---

有人能帮我吗？谢谢。

这是解决这个问题的方法之一

使用uibarbuttonite作为空间

let space = UIBarButtonItem(barButtonSystemItem: .FixedSpace, target: nil, action: nil)
space.width = -20 // adjust as needed
self.navigationItem.rightBarButtonItems = [pencilBtn, clipBtn, searchBtn, space]

---

我用这种方式解决了我的问题：

var searchImage = UIImage(named: "search-selected")!
var clipImage = UIImage(named: "clip")!
var pencilImage = UIImage(named: "pencil")!

let searchBtn: UIButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
searchBtn.setImage(searchImage, forState: UIControlState.Normal)
searchBtn.addTarget(self, action: "searchBtnPressed", forControlEvents: UIControlEvents.TouchUpInside)
searchBtn.frame = CGRectMake(0, 0, 30, 30)
let searchBarBtn = UIBarButtonItem(customView: searchBtn)

let clipBtn: UIButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
clipBtn.setImage(clipImage, forState: UIControlState.Normal)
clipBtn.addTarget(self, action: "clipBtnPressed", forControlEvents: UIControlEvents.TouchUpInside)
clipBtn.frame = CGRectMake(0, 0, 30, 30)
let clipBarBtn = UIBarButtonItem(customView: clipBtn)

let pencilBtn: UIButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
pencilBtn.setImage(pencilImage, forState: UIControlState.Normal)
pencilBtn.addTarget(self, action: "pencilBtnPressed", forControlEvents: UIControlEvents.TouchUpInside)
pencilBtn.frame = CGRectMake(0, 0, 30, 30)
let pencilBarBtn = UIBarButtonItem(customView: pencilBtn)

self.navigationItem.setRightBarButtonItems([pencilBarBtn, clipBarBtn, searchBarBtn], animated: false)

现在看起来不错

Swift 4.1的更新

let testButton : UIButton = UIButton.init(type: .custom)
testButton.setImage(editImage, for: .normal)
testButton.addTarget(self, action: #selector(didTapCameraButton), for: .touchUpInside)
testButton.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
let addButton = UIBarButtonItem(customView: testButton)

对于Swift 3：

let searchBtn: UIButton = UIButton(type: UIButtonType.custom)
searchBtn.setImage(UIImage(named: "search"), for: [])
searchBtn.addTarget(self, action: #selector(ViewController.searchBtnPressed(_:)), for: UIControlEvents.touchUpInside)
searchBtn.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
let searchButton = UIBarButtonItem(customView: searchBtn)

let clipBtn: UIButton = UIButton(type: UIButtonType.custom)
clipBtn.setImage(UIImage(named: "clip"), for: [])
clipBtn.addTarget(self, action: #selector(ViewController.clipBtnPressed(_:)), for: UIControlEvents.touchUpInside)
clipBtn.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
let clipButton = UIBarButtonItem(customView: clipBtn)

let pencilBtn: UIButton = UIButton(type: UIButtonType.custom)
pencilBtn.setImage(UIImage(named: "pencil"), for: [])
pencilBtn.addTarget(self, action: #selector(ViewController.pencilBtnPressed(_:)), for: UIControlEvents.touchUpInside)
pencilBtn.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
let pencilButton = UIBarButtonItem(customView: pencilBtn)

self.navigationItem.rightBarButtonItems = [pencilButton, clipButton, searchButton]

---

用视图控制器替换

ViewController

尝试更改

constraintEqualToConstant

[myUIButton.widthAnchor constraintEqualToConstant:24].active = YES;
[myUIButton.heightAnchor constraintEqualToConstant:24].active = YES;

---

此解决方案位于目标C中

UIImage *settingImageName = [UIImage imageNamed:@"Menu_Burger_Icon"];
UIButton * settingButton = [UIButton buttonWithType:UIButtonTypeCustom];
[settingButton setImage:settingImageName forState:UIControlStateNormal];
[settingButton addTarget:self action:@selector(settingsBtnClicked) forControlEvents:UIControlEventTouchUpInside];
settingButton.frame = CGRectMake(0, 0, 30, 30);

UIBarButtonItem *settingBarButton = [[UIBarButtonItem alloc] initWithCustomView:settingButton];

UIImage *notificationImageName = [UIImage imageNamed:@"NotificationON"];
UIButton * notificationButton = [UIButton buttonWithType:UIButtonTypeCustom];
[notificationButton setImage:notificationImageName forState:UIControlStateNormal];
[notificationButton addTarget:self action:@selector(notificationButtonClicked) forControlEvents:UIControlEventTouchUpInside];
notificationButton.frame = CGRectMake(0, 0, 30, 30);
UIBarButtonItem *notificationBarButton = [[UIBarButtonItem alloc] initWithCustomView:notificationButton];

self.navigationItem.rightBarButtonItems  = @[settingBarButton,notificationBarButton];

溶液参考@mikle94。他的回答很快

您也可以在故事板中首先连接内容。

let rightActionButton:UIButton = UIButton()

if #available(iOS 11.0, *) {

    let widthConstraint = rightActionButton.widthAnchor.constraint(equalToConstant: 30)
    let heightConstraint = rightActionButton.heightAnchor.constraint(equalToConstant: 30)
    heightConstraint.isActive = true
    widthConstraint.isActive = true
}
else {
    rightActionButton.frame = CGRect.init(x: 0, y: 0, width: 30, height: 30)
}

rightActionButton.setImage(UIImage.init(named: "3-dots-right-button"), for: .normal)
rightActionButton.addTarget(self, action: #selector(handleRightMenu), for: UIControlEvents.touchUpInside)
rightActionButton.setTitle("", for: .normal)
rightActionButton.tintColor = UIColor(hex:K.NODD_GREEN_HEX)


let rightActionBarButton:UIBarButtonItem = UIBarButtonItem(customView: rightActionButton)

let rightBarButtonItem1 = rightActionBarButton
let rightBarButtonItem2 = UIBarButtonItem(barButtonSystemItem: .action, target: self, action: #selector(handleRight2Menu))

self.navigationItem.rightBarButtonItems = [rightBarButtonItem1,rightBarButtonItem2]

我有两个右栏按钮项

（这是objective-c代码，您可以为swift修改。）

首先在视图控制器中创建对它们的引用

@interface MyViewController ()
    @property (weak, nonatomic) IBOutlet UIButton *smsButton;
    @property (weak, nonatomic) IBOutlet UIButton *checkoutButton;
@end

然后，在viewDidLoad中，调整其宽度和高度

// Adjust right bar button item spacing.
self.smsButton.frame = CGRectMake(0, 0, 30, 30);
self.lockButton.frame = CGRectMake(0, 0, 30, 30);

设置

testButton.frame

没有帮助

这个解决方案对我来说是正确的

rightButton.imageEdgeInsets = UIEdgeInsets(top: 3, left: 10, bottom: 7, right: 0)

通过@mkz支持解决方案，使用函数减少代码（Swift 4.2.1）

在函数中添加了最重要的参数（注意如何将选择器传递给函数），您可能需要根据需要添加更多参数

func makeCustomNavigationButton(imageName: String, action: Selector) -> UIBarButtonItem{

    let image = UIImage(named: imageName)!
    let btn: UIButton = UIButton(type: UIButton.ButtonType.custom)
    btn.setImage(image, for: .normal)
    btn.addTarget(self, action: action, for: .touchUpInside)
    btn.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
    let barBtn = UIBarButtonItem(customView: btn)

    return barBtn
}

如何致电：

let search = self.makeCustomNavigationButton(imageName: "search", action: #selector(searchBtnPressed(_:)))
let clip = self.makeCustomNavigationButton(imageName: "clip", action: #selector(clipBtnPressed(_:)))
let pencil = self.makeCustomNavigationButton(imageName: "pencil", action: #selector(pencilBtnPressed(_:)))
self.navigationItem.rightBarButtonItems = [search, clip, pencil]

导航栏忽略间距。是否在iOS上使用UIBarButton containerView初始化器使用Roboto字体？异端D@RicardoSánchez-Sáez它是在PRD中指定的。你可以使用一个函数，而不是重复所有的代码。但是，谢谢你，它成功了！一个完美的答案我喜欢这个。下面我将给出我想要的答案，但是设置框架对我来说不是必要的，所以我留下了那一行。但是如果这些条形按钮不是自定义的条形按钮，而是由系统提供的，比如“完成”、“相机”或“编辑”，该怎么办。只需使用

customView

初始值设定项而不是带有

image

的初始值设定项，就可以得到正确的结果，因为图像没有像看上去那样插入。

let search = self.makeCustomNavigationButton(imageName: "search", action: #selector(searchBtnPressed(_:)))
let clip = self.makeCustomNavigationButton(imageName: "clip", action: #selector(clipBtnPressed(_:)))
let pencil = self.makeCustomNavigationButton(imageName: "pencil", action: #selector(pencilBtnPressed(_:)))
self.navigationItem.rightBarButtonItems = [search, clip, pencil]
