let notificationButton = UIBarButtonItem(image:UIImage(named: "ic_notifications.png")?.withRenderingMode(.alwaysOriginal), style: .plain, target: self, action: #selector(DashboardViewController.notificationImageClick))
self.tabBarController?.navigationItem.rightBarButtonItems = [threeDotButton,notificationButton]
let title = UILabel()
title.text = "Dashboard"
self.tabBarController?.navigationItem.leftBarButtonItem = UIBarButtonItem.init(customView: title)

I've not found on stackoverflow a modern solution how to make a Safari-style back button for UIBarButtonItem. Is there a simple and elegant way to implement a back button as it is in Safari?
If you are targeting iOS13 and above, you can use the built-in SF Symbols library provided by Apple.
The chevron.left image is used for the Safari back button.
let chevronLeft = UIImage(systemName: "chevron.left")
let backButton = UIBarButtonItem(image: chevronLeft, style: .plain, target: webView, action: #selector(webView!.goBack))
These icons also come in nine weights from ultralight to black, which can be applied like this.
let chevronLeft = UIImage(systemName: "chevron.left", withConfiguration: UIImage.SymbolConfiguration(weight: .thin))
More information is available from Apple here: SF Symbols
I have found solution. The best way is to find back button image on web and use this code:
let backIcon = UIImage(named: "backIcon")
let backButton = UIBarButtonItem(image: backIcon, style: .plain, target: webView, action: #selector(webView!.goBack))
For example:
On iOS 10 and below my bar buttons are positioned incorrectly within the nav bar. What could be causing this?
This is the function to set the button:
func setBarButton(image: UIImage?, position: BarButtonPosition, target: AnyObject, selector: Selector) -> Void {
let barButton = UIBarButtonItem(title: "", style: .plain, target: target, action: selector)
barButton.image = image
if position == .left {
navigationItem.leftBarButtonItem = barButton
navigationItem.leftBarButtonItem?.tintColor = UIColor.zbPrimary
} else {
navigationItem.rightBarButtonItem = barButton
navigationItem.rightBarButtonItem?.tintColor = UIColor.zbPrimary
}
}
And where I am calling the function within viewDidLoad:
setBarButton(image: #imageLiteral(resourceName: "settings-icon"), position: .right, target: self, selector: #selector(openSettings))
This only happens for UIBarButtonItem where an image is being set, not those with just a title or custom view
The title of your question was misleading but after reading your question I realized it was the same problem I had on one of my projects.
I was setting the barButtonItem title through code and when I changed it from:
navigationItem.leftBarButtonItem?.title = ""
To:
navigationItem.leftBarButtonItem?.title = nil
The problem disappeared.
I almost lost a entire day to fix this.
I hope this solves the problem for you.
Hopefully, this is an easy question. I am trying to obtain the UIView of a UIBarButtonItem. Looking at the following StackOverflow question I came up with the following code:
let notificationButton = UIBarButtonItem(image: UIImage(named: "icon_notification.png"), style: .plain, target: self, action: nil)
let notificationView = notificationButton.value(forKey: "view") as? UIView
However, notificationView is nil. So, thoughts on what I failed to interpret from the linked StackOverflow question?
Starting from iOS 11 this code will not work cause line of code below will not cast UIView. Also it's counting as private API and seems to be will not pass AppStore review.
guard let view = self.value(forKey: "view") as? UIView else { return }
Thread on: forums.developer.apple
So, DS Dharma gave me a idea which ended up working. The "view" value is only available after it is assigned to the toolbar navigation item like this:
self.navigationItem.rightBarButtonItem = UIBarButtonItem(image: UIImage(named: "icon_notification.png"), style: .plain, target: self, action: nil)
self.navigationItem.rightBarButtonItem?.addBadge(number: 0, withOffset: CGPoint(x: 7.0, y: 0.0) , andColor: UIColor.black, andFilled: true)
where the addBadge() function needs the UIView. BTW, if anyone is wondering, the addBadge function was taken from this post: http://www.stefanovettor.com/2016/04/30/adding-badge-uibarbuttonitem
Highly recommended if you need this piece of functionality.
Hi I saw too many tutorial from stack overflow for how to change backBarButton I change it but when I check I see my image(custom arrow) beside (default arrow blue one ) I see both beside of each other
I mean the back text changed but the arrow doesn't I see my custom arrow beside default iOS arrow I don't know how should I change it to see my custom arrow only ???
for more detail please check this picture to see this problem
HERE
First You need to hide the default back Button , then supply your Custom one. Following code will help you.
self.navigationItem.hidesBackButton = true
let back: UIButton = UIButton(type: UIButtonType.custom)
back.setImage(UIImage(named: "backarrow"), for: UIControlState.normal)
back.frame = CGRect(x: 0, y: 0, width: 22, height: 22)
back.addTarget(self, action: #selector(self.backPressed), for: UIControlEvents.touchUpInside)
let left: UIBarButtonItem = UIBarButtonItem(customView: back)
self.navigationItem.setLeftBarButton(left, animated: true)
self.navigationController?.navigationBar.topItem?.title = ""
func backPressed() {
//Do your menupulation
}
If I understand you correctly you just need to place your button into Navigation Bar and then set your image name into "image" field.
http://take.ms/Rfrtf - here is for example ;)
Solution 1
You can set default back button color's tint color to red .
UINavigationBar.appearance().tintColor = UIColor.red // add this line appdelegate
Solution 2
self.navigationItem.leftItemsSupplementBackButton = YES;
self.navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: UIBarButtonItemStyle.plain, target: nil, action: nil)
or
self.navigationItem.leftBarButtonItems = #[customBackButtonItem];
I want to use some of default iOS icons i.e.
in navigation bar.
Basically I don't know how to call image of that item (directly from native library - I know how to download it and place as custom image:)):
var myButton:UIButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
myButton.addTarget(self, action: "reload", forControlEvents: UIControlEvents.TouchUpInside)
myButton.setImage(???, forState: <#UIControlState#>)
You can use UIBarButtonSystemItem this way:
let button = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Refresh, target: self, action: "someAction")
navigationItem.leftBarButtonItem = button
Result for leftBarButtonItem:
If you want to set it at right side you can use this code:
navigationItem.rightBarButtonItem = button
Result for rightBarButtonItem:
Swift: These are the most commonly used options:
To Use custom image with original colour:
let customImageBarBtn1 = UIBarButtonItem(
UIImage(named: "someImage.png").withRenderingMode(.alwaysOriginal),
style: .plain, target: self, action: #selector(handleClick))
To Use custom image with tint colour:
let customImageBarBtn2 = UIBarButtonItem(
UIImage(named: "someImage.png").withRenderingMode(.alwaysTemplate),
style: .plain, target: self, action: #selector(handleClick))
Or use system provided buttons:
let systemBarBtn = UIBarButtonItem(
barButtonSystemItem: .search,
target: self, action: #selector(handleClick))
Then add any one of these buttons to the navigationItem:
navigationItem.leftBarButtonItems = [customImageBarBtn1, customImageBarBtn2]
navigationItem.rightBarButtonItems = [systemBarBtn]
// OR you can use this if there's only one item.
navigationItem.rightBarButtonItem = systemBarBtn
For custom Images: As a starting size, 22ptx22pt images work well for the default iPhone Navigation Bar size.
In swift 4.3
let btnRefresh = UIBarButtonItem(barButtonSystemItem: UIBarButtonItem.SystemItem.refresh, target: self, action: #selector(targeted function to invoke))
//If you want icon in left side
navigationItem.leftBarButtonItem = btnRefresh
//If you want icon in right side
navigationItem.rightBarButtonItem = btnRefresh
