Circular UIBarButtonItem button image get stretched - ios

Added circular button on self.navigationItem.leftBarButtonItem for specific UIViewController of a TabBarcontroller after switching one tab and getting back to specific tab. The circular button is stretched.
override func viewDidLoad() {
infoButton = UIButton(frame: CGRect(x: 0, y: 0, width: 40, height: 40))
infoButton.sd_setBackgroundImage(with: URL(string: "https://www.w3schools.com/howto/img_avatar.png"), for: .normal)
infoButton.addTarget(self, action: #selector(menuButtonPressed), for: .touchUpInside)
infoButton.layer.cornerRadius = infoButton.bounds.size.width / 2
infoButton.clipsToBounds = true
infoButton.layer.borderWidth = 1.0
infoButton.imageView?.contentMode = .scaleToFill
infoButton.layer.borderColor = UIColor.init(hexString: "#AAC8FF").cgColor
let infoItem = UIBarButtonItem(customView: infoButton)
self.navigationItem.leftBarButtonItem = infoItem
}
Error Image:

You forgot to give infoButton a size. You have to use auto layout. Give it a width constraint with a constant 40 and a height constraint with a constant 40.

How to fit an image in rightbarbuttonitem

I've been trying to put a hamburger button (the three parallel lines) to the right of the titleView in the nav bar, but every time I do, the image I put in covers the entire nav bar and gets rid of the image I have in titleView.
If I select a default image in the storyboard editor it will appear on the right side of the nav bar without any problems, but as soon as I select the hamburger button in the storyboard editor I get the same problem as before. I've tried with multiple different images and I've changed up the code a little bit with no success. Is there a way to resize the image I'm using so it will fit in the nav bar properly or is there just something wrong with my code?
Here is my code from viewController.swift below:
override func viewDidAppear(_ animated: Bool) {
let nav = self.navigationController?.navigationBar
let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 40, height: 40))
imageView.contentMode = .scaleAspectFit
let titleImage = UIImage(named: "logowhitecircle")
imageView.image = titleImage
navigationItem.titleView = imageView
let menuButton = UIButton(frame: CGRect(x: 0, y: 0, width: 40, height: 40))
menuButton.contentMode = .scaleAspectFit
let menuImage = UIImage(named: "hamburgericon")
menuButton.setImage(menuImage, for: .normal)
self.navigationItem.rightBarButtonItem = UIBarButtonItem(customView: menuButton)
You need to set image size in the image assets like 3x = 84px, 2x=56px, 1x = 28px,
see the apple document for more info: https://developer.apple.com/design/human-interface-guidelines/ios/icons-and-images/custom-icons/
let menuButton = UIBarButtonItem(image: UIImage(named: "logowhitecircle"), style: .plain, target: self, action: #selector(menuButtonTapped(_:)))
self.navigationItem.rightBarButtonItem = menuBu
tton
Try Using below code:
let imageBurger = UIImage(named: "hamburgericon")!
let btnLeftMenu = UIButton(type: .system)
btnLeftMenu.bounds = CGRect(x: 10, y: 0, width: imageBurger.size.width, height: imageBurger.size.height)
btnLeftMenu.contentEdgeInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
btnLeftMenu.setImage(imageBurger, for: UIControl.State())
btnLeftMenu.setTitle(title, for: .normal)
let leftButton = UIBarButtonItem(customView: btnLeftMenu)
self.navigationItem.leftBarButtonItem = leftButton
Try this module FFBadgedBarButtonItem it's easy to use module, here is the documenataion Link
Below is my code how to implement it!
let image = UIImage(named: "yourImage")
let finalImage = resizeImage(image: image!, newWidth: 30)
navigationItem.rightBarButtonItem = FFBadgedBarButtonItem(image: finalImage, target: self, action: #selector(rightButtonTouched))
And here is the calling function
#objc func rightButtonTouched() {
// what event you need to perfom by clicking on this button
}
You need to create Bridging Header to work with this Obj-C module.
: D
Try this:
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: "hamburgericon"), forState: UIControlState.Normal)
//add function for button
button.addTarget(self, action: "customButtonPressed", forControlEvents: UIControlEvents.TouchUpInside)
//set frame
button.frame = CGRectMake(0, 0, 40, 40)
let barButton = UIBarButtonItem(customView: button)
//assign button to navigationbar
self.navigationItem.rightBarButtonItem = barButton
}
//This method will call when you press button.
func customButtonPressed() {
println("button pressed")
}
}

how to set the image position and size of image that inserted in navigation bar?

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.

button does not work after adding uiview in swift 4

let SearchView = UIView()
SearchView.backgroundColor = UIColor.clear
SearchView.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
let Searchbutton = UIButton(type: .system)
Searchbutton.setImage(UIImage (named: "SEARCH"), for: .normal)
Searchbutton.backgroundColor = .clear
Searchbutton.frame = CGRect(x: -17, y: -20, width: 30, height: 30)
Searchbutton.contentMode = .scaleAspectFit
let WidthConstraint = Searchbutton.widthAnchor.constraint(equalToConstant: 30)
let HeightConstraint = Searchbutton.heightAnchor.constraint(equalToConstant: 30)
WidthConstraint.isActive = true
HeightConstraint.isActive = true
let barButtonItem = UIBarButtonItem(customView: SearchView)
self.navigationItem.rightBarButtonItem = barButtonItem
SearchView.addSubview(Searchbutton)
Searchbutton.addTarget(self, action: #selector(viewanewcontroller(button:)), for: .touchUpInside)
//right search button
After making a button, I wanted to move it little bit to the right. So, i made UI View to move the button inside the view. But, then, after this, the button does not work anymore. Can anyone tell me the solution?
Your code is working fine but need to clarify some points.
Reason Your button not working is below 4 lines
let WidthConstraint = Searchbutton.widthAnchor.constraint(equalToConstant: 30)
let HeightConstraint = Searchbutton.heightAnchor.constraint(equalToConstant: 30)
WidthConstraint.isActive = true
HeightConstraint.isActive = true
As you already set UIButton frame then no need to use of above lines of code.
Yellow color view is your SearchView and green color is your UIButton.
If you use Searchbutton frame like Searchbutton.frame = CGRect(x: -17, y: -20, width: 30, height: 30) then it happens something like below image.
You added UIButton as subview of UIView and when you click on green button which is inside yellow View will work but the area which is outside Yellow area doesn't work.
You need to start UIButton frame from 0,0,30,30
Searchbutton.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
or you can directly set UIButton frame same as UIView frame then it looks like below image.
Searchbutton.frame = SearchView.frame
Below is your Working Code.
let SearchView = UIView()
SearchView.backgroundColor = UIColor.clear
SearchView.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
let Searchbutton = UIButton(type: .system)
Searchbutton.setImage(UIImage (named: "SEARCH"), for: .normal)
Searchbutton.backgroundColor = .clear
Searchbutton.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
Searchbutton.contentMode = .scaleAspectFit
let barButtonItem = UIBarButtonItem(customView: SearchView)
self.navigationItem.rightBarButtonItem = barButtonItem
SearchView.addSubview(Searchbutton)
Searchbutton.addTarget(self, action: #selector(viewanewcontroller(button:)), for: .touchUpInside)
//right search button
You're doing a lot of unnecessary things here. Firstly, you don't need to put your Button in a container view to put it as the right bar button item.
You also don't need to add constraints to your searchbutton, since you have given it a fixed frame.
let Searchbutton = UIButton(type: .system)
Searchbutton.setImage(UIImage (named: "SEARCH"), for: .normal)
Searchbutton.backgroundColor = .clear
Searchbutton.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
Searchbutton.contentMode = .scaleAspectFit
let barButtonItem = UIBarButtonItem(customView: Searchbutton)
self.navigationItem.rightBarButtonItem = barButtonItem
Searchbutton.addTarget(self, action: #selector(viewanewcontroller(button:)), for: .touchUpInside)
Also as Pratik's comment said, you're meant to use lower camel case. so SearchView should be searchView and SearchButton as searchButton
As for moving it to the right, it seems like that isn't possible anymore without either subclassing the UINavigationBar and changing the implementation, or by making UIViews look exactly like the standard Navigation Bar.

image and text for nav bar button item. swift

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]

Adding a custom navigation bar covering content in screen

I have added a custom navigation bar via storyboard. I was expecting the content on the screen to automatically shift downward. but instead it completely covers content on the top of the screen.. is there a clean line of code that automatically creates that spacing between the navigation bar and the view itself?
You might have heard about Cocpods which i feel is a better way to go for cutsom Navigation bar.
You just need to implement the protocol and give the specifications you need for the Navigation bar
Go through the following cooped
https://cocoapods.org/pods/resizable-navigation-bar
Just call this method from viewDidLoad :
func createNavBar() {
let leftNavigationButton = UIButton()
leftNavigationButton.setImage(UIImage(named: "ic_back.png"), forState: .Normal)
leftNavigationButton.frame = CGRectMake(10, 10, 20, 15)
leftNavigationButton.addTarget(self, action: "onBackButtonPressed:", forControlEvents: UIControlEvents.TouchUpInside)
let customBarItem = UIBarButtonItem(customView: leftNavigationButton)
self.navigationItem.leftBarButtonItem = customBarItem;
//set TitleAppIcon
let GR = UITapGestureRecognizer(target: self, action: Selector("headerLogoTapAction:"))
let imageView = UIImageView(frame: CGRect(x: 90, y: 0, width: ((UIScreen.mainScreen().bounds.width)/3), height: 40))
imageView.contentMode = .ScaleAspectFit
let image = UIImage(named: "yourimag.png") //or set title
imageView.image = image
imageView.addGestureRecognizer(GR)
imageView.userInteractionEnabled = true
navigationItem.titleView = imageView
}
Hope this gonna help you
