navigation bar right bar button items spacing

Question

I have created a with left bar button item added from storyboard, titleView and three right bar button items from code.

Here is the code:

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)
}

My problem is that I want to change the spacing between right buttons but I don't know how.

I've tried to add a fixedButton between them but it just increased the existing space.

Can some one help me? Thanks.

Solution 1

I solved my problem in this way:

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)

Now it looks good,

Update for 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)

Solution 2

For 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]

Replace ViewController with your view controller

Solution 3

Set testButton.frame doesn't help.

This solution is correct for me!

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

Solution 4

This solution is in 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];

Solution 5

// 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
