I am trying to set an Image for bar button Item for that I have an image like:
with resolution 30 * 30 but while I assign this Image to Bar button Its looks like:
I have assigned image this way :
and If I try this way like making an IBOutlet for the button and set Image programatically form this question and code for that is:
// Outlet for bar button
#IBOutlet weak var fbButton: UIBarButtonItem!
// Set Image for bar button
var backImg: UIImage = UIImage(named: "fb.png")!
fbButton.setBackgroundImage(backImg, forState: .Normal, barMetrics: .Default)
but nothing happend with this,
Can anybody tell me what I am doing wrong?
or which is the batter way to do this?
I have achieved that programatically with this code:
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
//create a new button
let button: UIButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
//set image for button
button.setImage(UIImage(named: "fb.png"), forState: UIControlState.Normal)
//add function for button
button.addTarget(self, action: "fbButtonPressed", forControlEvents: UIControlEvents.TouchUpInside)
//set frame
button.frame = CGRectMake(0, 0, 53, 31)
let barButton = UIBarButtonItem(customView: button)
//assign button to navigationbar
self.navigationItem.rightBarButtonItem = barButton
}
//This method will call when you press button.
func fbButtonPressed() {
println("Share to fb")
}
}
And result will be:
Same way you can set button for left side too this way:
self.navigationItem.leftBarButtonItem = barButton
And result will be:
And if you want same transaction as navigation controller have when you go back with default back button then you can achieve that with custom back button with this code:
func backButtonPressed(sender:UIButton) {
navigationController?.popViewControllerAnimated(true)
}
For swift 3.0:
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
//create a new button
let button = UIButton.init(type: .custom)
//set image for button
button.setImage(UIImage(named: "fb.png"), for: UIControlState.normal)
//add function for button
button.addTarget(self, action: #selector(ViewController.fbButtonPressed), for: UIControlEvents.touchUpInside)
//set frame
button.frame = CGRect(x: 0, y: 0, width: 53, height: 51)
let barButton = UIBarButtonItem(customView: button)
//assign button to navigationbar
self.navigationItem.rightBarButtonItem = barButton
}
//This method will call when you press button.
func fbButtonPressed() {
print("Share to fb")
}
}
For swift 4.0:
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
//create a new button
let button = UIButton(type: .custom)
//set image for button
button.setImage(UIImage(named: "fb.png"), for: .normal)
//add function for button
button.addTarget(self, action: #selector(fbButtonPressed), for: .touchUpInside)
//set frame
button.frame = CGRect(x: 0, y: 0, width: 53, height: 51)
let barButton = UIBarButtonItem(customView: button)
//assign button to navigationbar
self.navigationItem.rightBarButtonItem = barButton
}
//This method will call when you press button.
#objc func fbButtonPressed() {
print("Share to fb")
}
}
An easy solution may be the following
barButtonItem.image = UIImage(named: "image")
then go to your Assets.xcassets select the image and go to the Attribute Inspector and select "Original Image" in Reder as option.
Similar to the accepted solution, but you can replace the
let button: UIButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
with
let button = UIButton()
Here is the full solution, enjoy: (it's just a bit cleaner than the accepted solution)
let button = UIButton()
button.frame = CGRectMake(0, 0, 51, 31) //won't work if you don't set frame
button.setImage(UIImage(named: "fb"), forState: .Normal)
button.addTarget(self, action: Selector("fbButtonPressed"), forControlEvents: .TouchUpInside)
let barButton = UIBarButtonItem()
barButton.customView = button
self.navigationItem.rightBarButtonItem = barButton
Here's a simple extension on UIBarButtonItem:
extension UIBarButtonItem {
class func itemWith(colorfulImage: UIImage?, target: AnyObject, action: Selector) -> UIBarButtonItem {
let button = UIButton(type: .custom)
button.setImage(colorfulImage, for: .normal)
button.frame = CGRect(x: 0.0, y: 0.0, width: 44.0, height: 44.0)
button.addTarget(target, action: action, for: .touchUpInside)
let barButtonItem = UIBarButtonItem(customView: button)
return barButtonItem
}
}
Only two Lines of code required for this
Swift 3.0
let closeButtonImage = UIImage(named: "ic_close_white")
navigationItem.rightBarButtonItem = UIBarButtonItem(image: closeButtonImage, style: .plain, target: self, action: #selector(ResetPasswordViewController.barButtonDidTap(_:)))
func barButtonDidTap(_ sender: UIBarButtonItem)
{
}
I am using latest swift (2.1) and the answer (Dharmesh Kheni and jungledev) does not work for me. The image color was off (when setting in IB, it was blue and when setting directly in UIButton, it was black). It turns out I could create the same bar item with the following code:
let barButton = UIBarButtonItem(image: UIImage(named: "menu"), landscapeImagePhone: nil, style: .Done, target: self, action: #selector(revealBackClicked))
self.navigationItem.leftBarButtonItem = barButton
You can use this code for multiple bar button with custom image:
self.navigationItem.leftBarButtonItem = nil
let button = UIButton(type: .custom)
button.setImage(UIImage (named: "ChatTab"), for: .normal)
button.frame = CGRect(x: 0.0, y: 0.0, width: 35.0, height: 35.0)
//button.addTarget(target, action: nil, for: .touchUpInside)
let barButtonItem = UIBarButtonItem(customView: button)
let button2 = UIButton(type: .custom)
button2.setImage(UIImage (named: "ActivityTab"), for: .normal)
button2.frame = CGRect(x: 0.0, y: 0.0, width: 35.0, height: 35.0)
//button.addTarget(target, action: nil, for: .touchUpInside)
let barButtonItem2 = UIBarButtonItem(customView: button2)
self.navigationItem.rightBarButtonItems = [barButtonItem, barButtonItem2]
Result will be this:
Initialize barbuttonItem like following:
let pauseButton = UIBarButtonItem(image: UIImage(named: "big"),
style: .plain,
target: self,
action: #selector(PlaybackViewController.pause))
Your problem is because of the way the icon has been made - it doesn't conform to Apple's custom tab bar icon specs:
To design a custom bar icon, follow these guidelines:
Use pure white with appropriate alpha transparency.
Don’t include a drop shadow.
Use antialiasing.
(From the guidelines.)
Something that would be possible looks like this. You can find such icons on most free tab bar icon sites.
Swift 4.
#IBOutlet weak var settingBarBtn: UIBarButtonItem! {
didSet {
let imageSetting = UIImageView(image: UIImage(named: "settings"))
imageSetting.image = imageSetting.image!.withRenderingMode(.alwaysOriginal)
imageSetting.tintColor = UIColor.clear
settingBarBtn.image = imageSetting.image
}
}
SwiftUI
.navigationBarItems modifier takes any view you want:
struct ContentView: View {
var body: some View {
NavigationView {
Text("SwiftUI")
.navigationBarItems(leading:
HStack {
Image(systemName: "trash")
Text("Trash")
}
)
}
}
}
.navigationBarItems(trailing: Image(systemName: "trash") )
.navigationBarItems(leading: Image(systemName: "trash.fill"),
trailing: Image(systemName: "trash")
)
You can use a button for each if you need an action for each of them.
Swift 5+. Smooth solution to add ideal image as you desired dynamic Solution
func rightBarButtonItem(iconNameButton: String, selector: Selector) {
let button = UIButton()
button.frame = CGRect(x: 0, y: 0, width: 25, height: 25)
button.setImage(UIImage(named: iconNameButton), for: .normal)
button.addTarget(self, action: selector, for: .touchUpInside)
button.imageView?.contentMode = .scaleAspectFit
let buttonBarButton = UIBarButtonItem(customView: UIView(frame: CGRect(x: 0, y: 0, width: 25, height: 25)))
buttonBarButton.customView?.addSubview(button)
buttonBarButton.customView?.frame = button.frame
self.navigationItem.rightBarButtonItem = buttonBarButton
}
Just choose Original image option when adding an image to assets in Xcode
If your UIBarButtonItem is already allocated like in a storyboard.
(printBtn)
let btn = UIButton(frame: CGRect(x: 0, y: 0, width: 30, height: 30))
btn.setImage(UIImage(named: Constants.ImageName.print)?.withRenderingMode(.alwaysTemplate), for: .normal)
btn.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handlePrintPress(tapGesture:))))
printBtn.customView = btn
If you have set up your UIBarButtonItem with an image in the storyboard, one small hack to change the renderingMode is to add the following code to your viewDidLoad(). This way you don't have to resort to adding the entire button and image in code.
if let navButton = self.navigationItem.leftBarButtonItem, let buttonImage = navButton.image {
navButton.image = buttonImage.withRenderingMode(.alwaysOriginal)
}
navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Left",
style: .plain,target: self, action: #selector(rightbarButtonAction))
navigationItem.rightBarButtonItem?.image = UIImage(named: "Notification Bell")
actually I don't know the correct way how to make an image inside the navigation bar like this, either using navigation controller or by using custom view by myself
I need to insert these 2 image as bar button and image title
so I tried to use navigation controller and insert an image in viewDidLoad like the code below:
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// insert image title
let aspectRatio : CGFloat = 0.25
let widthOfImageHeader = view.frame.width * 0.5
let heightOfImageHeader = widthOfImageHeader * aspectRatio
let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: widthOfImageHeader, height: heightOfImageHeader))
imageView.contentMode = .scaleAspectFit
let image = UIImage(named: "testImage2")
imageView.image = image
navigationItem.titleView = imageView
// set bar button image
//create a new button
let button = UIButton(type: .custom)
//set image for button
button.setImage(UIImage(named: "hamburgerIcon"), for: .normal)
//set frame
button.frame = CGRect(x: 0, y: 0, width: 53, height: 51)
let barButton = UIBarButtonItem(customView: button)
//assign button to navigationbar
self.navigationItem.leftBarButtonItem = barButton
}
}
but the result is like the image below:
the position of image title is not exactly in the center for iPhone 5s and bar button seems a little bit off in the right.
and if I assign the image right bar button, using
/
/create a left button
let button = UIButton(type: .custom)
//set image for button
button.setImage(UIImage(named: "hamburgerIcon"), for: .normal)
//set frame
button.frame = CGRect(x: 0, y: 0, width: 53, height: 51)
let barButton = UIBarButtonItem(customView: button)
//assign button to navigationbar
self.navigationItem.leftBarButtonItem = barButton
//create a right button
let button2 = UIButton(type: .custom)
//set image for button
button2.setImage(UIImage(named: "backButton"), for: .normal)
//set frame
button2.frame = CGRect(x: 0, y: 0, width: 53, height: 51)
let barRightButton = UIBarButtonItem(customView: button)
//assign button to navigationbar
self.navigationItem.rightBarButtonItem = barRightButton
the result is even weirder
one of the button dissapears, the hamburger icon that should be on the left, now in the right
it will be far easier if I use custom view, but...is it weird if I use custom view that use like navigation bar? I am new in iOS Developer. Thanks in advance
Okay so here's what I usually do in a project with such kind of requirements (image at the navBar's title, and custom bar button items).
To answer first your question, you can actually do whatever you want.
Have indeed a custom view while having your viewController embedded inside a UINavigationController. But be sure to hide the navBar.
Have a visible navBar and viewContorller embedded in UINavigationController.
The ideal way for me is the latter.
The sample project below was made using my own old framework: https://github.com/glennposadas/gpkit-ios
You can copy any pieces of codes from that framework, modify/rename everything on it, and put in your production project.
If you want the result below, here's how I do it:
import GPKit
import UIKit
class ViewController: UIViewController {
// MARK: - Properties
internal lazy var button_Close: UIButton = {
let button = UIButton(type: .custom)
button.setImage(UIImage(named: "ham"), for: .normal)
button.imageEdgeInsets = UIEdgeInsets.init(top: 0, left: -30, bottom: 0, right: 0)
//button.addTarget(self, action: #selector(hamburger(_:)), for: .touchUpInside)
return button
}()
// MARK: - Functions
// MARK: Overrides
override func viewDidLoad() {
super.viewDidLoad()
GPLog(classSender: self, log: "viewDidLoad!")
// Title View Test: -
let navBarImage = UIImage(named: "ic_logo_navbar")!
self.setNavBarTitleWithFeedback(image: navBarImage, navBarTintColor: .white)
self.makeNavBarColor(color: UIColor.colorWithRGBHex(0x332F39), itemsTintColor: .white)
// Barbutton
let barButton = UIBarButtonItem(customView: self.button_Close)
self.button_Close.frame = CGRect(x: 0, y: 0, width: 55.0, height: 44.0)
let negativeSpacer = UIBarButtonItem(barButtonSystemItem: UIBarButtonItem.SystemItem.fixedSpace, target: nil, action: nil)
if #available(iOS 11.0, *) {
negativeSpacer.width = -30
}
self.navigationItem.leftBarButtonItems = [negativeSpacer, barButton]
}
}
extension ViewController: GPTitleViewDelegate {
func gpTitleView(userDidTapTitleView gpTitleView: GPTitleView) {
GPLog(classSender: self, log: "userDidTapTitleView🌈")
}
func gpTitleView(userDidFinishLongPress gpTitleView: GPTitleView) {
GPLog(classSender: self, log: "userDidFinishLongPress🌺")
}
}
Result:
I don't have your hex color, so it looks ugly.
I hope thish elps.
I have an programatically made nav button in navigation bar, I am trying to make image on the button(as like back button) and i made it, but my problem is, the button not appearing on the left corner, it appearing after some space.
let button = UIButton(type: .system)
button.frame = CGRect(x: 0, y: 0, width: 10, height: 40)
button.setTitle("Back", for: .normal)
button.setImage(UIImage(named: "ic_keyboard_arrow_left_2x"), for: .normal)
let barButton = UIBarButtonItem(customView: button)
self.navigationItem.leftBarButtonItems = [barButton]
please help me to acheive the task
Replace all code by :
self.navigationItem.backBarButtonItem = UIBarButtonItem(image: UIImage(named: "ic_keyboard_arrow_left_2x"), style: .plain, target: self, action: #selector(yourSelector))
self.navigationController?.navigationBar.topItem?.title = "Back"
I saw the answer for this question for adding an image to the left nav bar item. And I did it successfully.
But I also want to add a small text next to the image. For example I want to show how many coins the user have. So I need to show a coins image and the number of coins next to it. How can it be done?
I tried to set title (with "123"), but I only see the image and not the title. This my code:
let button = UIButton.init(type: .custom)
button.setImage(UIImage.init(named: "coins.png"), for: UIControlState.normal)
button.addTarget(self, action:#selector(self.callMethod), for: UIControlEvents.touchUpInside)
button.frame = CGRect.init(x: 0, y: 0, width: 30, height: 30)
button.setTitle("123", for: UIControlState.normal)
let barButton = UIBarButtonItem.init(customView: button)
self.navigationItem.leftBarButtonItem = barButton
Thanks.
Since the bar button item is initialized with a custom view, you can add a UIImage and a UILabel to one view, along with a UIButton to capture the touch event, and pass that into the initializer.
// the UIButton is simply there to capture touch up event on the entire bar button view.
let button = UIButton.init(type: .custom)
button.addTarget(self, action: #selector(buttonPressed), for: .touchUpInside)
let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 30, height: 30))
imageView.image = UIImage(named: "coins")
let label = UILabel(frame: CGRect(x: 35, y: 0, width: 50, height: 30))
label.text = "1234"
let buttonView = UIView(frame: CGRect(x: 0, y: 0, width: 90, height: 30))
button.frame = buttonView.frame
buttonView.addSubview(button)
buttonView.addSubview(imageView)
buttonView.addSubview(label)
let barButton = UIBarButtonItem.init(customView: buttonView)
self.navigationItem.leftBarButtonItem = barButton
You might have to adjust the frames accordingly for your own uses, of course.
I think your problem is the width it's 30 try to make it bigger like 50
let buttonContainer:UIView = UIView()
buttonContainer.frame = CGRect(x: 0, y: 0, width: 50, height: 32)
let image = UIImage(named: "coins")
let button = UIButton.init(type: .system)
button.setImage(image, for: .normal)
button.frame = buttonContainer.frame
button.setTitle("sss", for: .normal)
button.addTarget(self, action: #selector(action(_:)), for: .touchUpInside)
buttonContainer.addSubview(button)
self.navigationItem.leftBarButtonItem = UIBarButtonItem(customView: buttonContainer)
You can use backgroundImage for image and setTitle for test to the button.
follow this link definitely you will get idea:
image for nav bar button item swift
Use self.navigationItem.leftBarButtonItems that is an array of UIBarButtonItem
let button = UIBarButtonItem()
let text = UIBarButtonItem()
self.navigationItem.leftBarButtonItems = [button, text]
I am trying to set an Image for bar button Item for that I have an image like:
with resolution 30 * 30 but while I assign this Image to Bar button Its looks like:
