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         


        

Answer 1

Try to change the constraintEqualToConstant

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

Answer 2

Supporting solution by @mkz, by using function to reduce the code (Swift 4.2.1)

Added most important parameters to the function (note how to pass selector to a function), you may want to add more as per your need.

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
}

How to call:

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]

Answer 3

You can also wire things up first in Storyboard.
I have two right bar button items.

(This is objective-c code, which you can modify for swift.)

First create references to them in view controller.

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

Then, in viewDidLoad, adjust their widths and heights.

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

// 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

Answer 5

Set testButton.frame doesn't help.

This solution is correct for me!

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

Answer 6

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]
