导航栏右栏按钮项目间距
navigation bar right bar button items spacing
我创建了一个
从故事板、titleView 添加左栏按钮项，从代码添加三个右栏按钮项。
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)
}
我的问题是我想更改右键之间的间距，但我不知道如何更改。
我试图在它们之间添加一个 fixedButton，但它只是增加了现有的 space。
有人可以帮助我吗？谢谢
这是解决该问题的方法之一。
将 UIBarButtonItem 用作 space
let space = UIBarButtonItem(barButtonSystemItem: .FixedSpace, target: nil, action: nil)
space.width = -20 // adjust as needed
self.navigationItem.rightBarButtonItems = [pencilBtn, clipBtn, searchBtn, space]
我是这样解决问题的：
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，
更新 Swift 4.1
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]
用你的视图控制器替换ViewController
尝试改变constraintEqualToConstant
[myUIButton.widthAnchor constraintEqualToConstant:24].active = YES;
[myUIButton.heightAnchor constraintEqualToConstant:24].active = YES;
这个解决方案在Objective C
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];
@mikle94 的解决方案参考。他的答案在 Swift 中。
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]
// create three nav bar buttons
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()
// create a spacer
var space = UIBarButtonItem(barButtonSystemItem: .fixedSpace, target: self, action: nil)
space.width = 10
var buttons = [pencilBtn, space, clipBtn, space, searchBtn]
navigationItem?.rightBarButtonItems = buttons
您也可以先在 Storyboard 中进行连接。
我有两个右栏按钮项。
（这是 objective-c 代码，您可以为 swift 修改它。）
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，调整它们的宽高。
// 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)
支持@mkz的解决方案，使用函数减少代码(Swift 4.2.1)
向函数添加了最重要的参数（注意如何将选择器传递给函数），您可能希望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
}
如何调用：
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]
我创建了一个
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)
}
