I have the following code that adds a UIToolbar on the top of the keyboard when a textField is tapped.
How can I add a background image to one of the buttons?
I tried...
toolBar.items![1].setBackButtonBackgroundImage(clearButton, forState:.Normal, barMetrics:.Default)
but it didn't work, I get error...
Use of unresolved identifier 'imageName'
Code:
func addButtonsToKeyboard(){
let toolBar = UIToolbar(frame: CGRectMake(0, 0, self.view.frame.size.width, 50))
toolBar.barStyle = UIBarStyle.Default
toolBar.tintColor = UIColor.blueColor()
toolBar.barTintColor = UIColor.grayColor()
toolBar.items = [
UIBarButtonItem(title: "Button1", style: UIBarButtonItemStyle.Plain, target: self, action: #selector(someFunction)),
UIBarButtonItem(title: "Button2", style: UIBarButtonItemStyle.Plain, target: self, action: #selector(someFunction)),
UIBarButtonItem(title: "Button3", style: UIBarButtonItemStyle.Plain, target: self, action: #selector(someFunction))]
toolBar.sizeToFit()
toolBar.items![1].setBackButtonBackgroundImage(myImage, forState:.Normal, barMetrics:.Default)
myTextField.inputAccessoryView = toolBar
}
BTW - The image myImage is located in Assets.xcassets.
Perhaps you could try to create a UIImage variable, and then pass that in just to be more explicit:
var myImage = UIImage(named: "myImage")
toolBar.items![1].setBackButtonBackgroundImage(myImage, forState:.Normal, barMetrics:.Default)

I want to design a navigation View like.
1. Left Menu , and title in center
2. Left Menu , and Image just next to it, and left side button
i am trying to add buttons like this , but button is not properly showing
func addMenuButton(){
let btn_menu = UIButton(frame: CGRect(x: 0, y: 0, width: 40, height: 44))
btn_menu.addTarget(self, action: #selector(self.refreshBtnClicked), for: .touchUpInside)
btn_menu.setImage(#imageLiteral(resourceName: "ic_menu"), for: .normal)
btn_menu.setImage(#imageLiteral(resourceName: "ic_menu"), for: .selected)
self.navigationController?.navigationItem.leftBarButtonItems = [UIBarButtonItem(customView: btn_menu)]
}
//Option 1
self.title = "Title Here"
self.navigationItem.leftBarButtonItem = UIBarButtonItem(image: UIImage(named: "menu"), style: .plain, target: self, action: #selector(menuBtnAction(_:)))
//Option 2
let plusBtn = UIBarButtonItem(image: UIImage(named: "plus"), style: .plain, target: self, action: #selector(plusBtnAction(_:)))
let logoView = UIImageView(image: UIImage(named:"ins"))
logoView.translatesAutoresizingMaskIntoConstraints = false
logoView.widthAnchor.constraint(equalToConstant: 180).isActive = true
self.navigationItem.leftBarButtonItems = [plusBtn,UIBarButtonItem(customView: logoView)]
let titleLabel = UILabel()
titleLabel.text = "Main Controller"
titleLabel.frame = self.navigationController!.view.frame
titleLabel.textAlignment = .left
self.navigationItem.titleView = titleLabel
self.navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(tapped))
self.navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: .save, target: self, action: #selector(tapped))
Try like this
func addMenuButton(){
let leftBarButtonItem : UIBarButtonItem? = UIBarButtonItem(image: #imageLiteral(resourceName: "ic_menu"), style: UIBarButtonItem.Style.plain, target: self, action: #selector(refreshBtnClicked))
self.navigationController?.navigationItem.leftBarButtonItem = leftBarButtonItem;
}
I am trying to add two bar buttons to toolbar in iOS [Cancel] & [Save] on right and left side accordingly.
I used a third bar button [Spacer] and set it to be [.flexiblewidth] Otherwise, when adding it only the left button appears [Cancel] and the [Spacer] & and [Save] which have to be next disappearing ?
the screen shot is in the link:
https://ibb.co/cZsaVV
let pickerView = UIPickerView()
override func viewDidLoad() {
pickerView.addSubview(self.setToolBar())
}
func setToolBar() -> UIToolbar {
let toolBar = UIToolbar()
toolBar.isTranslucent = true
toolBar.backgroundColor = UIColor.clear
let barButtonAttr = [NSAttributedString.Key.font : UIFont.systemFont(ofSize: 15),
NSAttributedString.Key.foregroundColor : UIColor.black]
// [Save] BarButtonItem
let saveBarButtonItem = UIBarButtonItem(barButtonSystemItem: UIBarButtonItem.SystemItem.save, target: self, action: nil)
saveBarButtonItem.setTitleTextAttributes(barButtonAttr, for: .normal)
// [Cancel] BarButtonItem
let cancelBarButtonItem = UIBarButtonItem(barButtonSystemItem: UIBarButtonItem.SystemItem.cancel, target: self, action: nil)
cancelBarButtonItem.setTitleTextAttributes(barButtonAttr, for: .normal)
let spacerBarButtonItem = UIBarButtonItem(barButtonSystemItem: UIBarButtonItem.SystemItem.flexibleSpace ,
target: self, action: nil)
spacerBarButtonItem.setTitleTextAttributes(barButtonAttr, for: .normal)
// add BarButtonItems to toolBar
toolBar.items = [cancelBarButtonItem,spacerBarButtonItem,saveBarButtonItem]
toolBar.sizeToFit()
return toolBar
}
func createAccessoryViewWithTarget(_ target: AnyObject, width: CGFloat) -> UIView {
// Previous button
let previousButton = UIBarButtonItem(title: "Previous", style: .plain, target: target, action: #selector(self.moveToPreviousTextField))
previousButton.tintColor = UIColor.white
//Next button
let nextButton = UIBarButtonItem(title: "Next", style: .plain, target: target, action: #selector(self.moveToNextTextField))
nextButton.tintColor = UIColor.white
// Dismiss/close/done button
let doneButton = UIBarButtonItem(title: "Done", style: .done, target: target, action: #selector(self.keyboardDoneButtonTapped))
doneButton.tintColor = UIColor.white
let keyboardToolbar: UIToolbar = UIToolbar(frame: CGRect(x: 0, y: 0, width: width, height: 44))
keyboardToolbar.barStyle = .black
let flexSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
let fixedSpace = UIBarButtonItem(barButtonSystemItem: .fixedSpace, target: nil, action: nil)
var itemsArray = [UIBarButtonItem]()
itemsArray.append(previousButton)
itemsArray.append(fixedSpace)
itemsArray.append(nextButton)
itemsArray.append(flexSpace)
itemsArray.append(doneButton)
keyboardToolbar.items = itemsArray
keyboardToolbar.sizeToFit()
return keyboardToolbar
}
This one is old code may be swift3 I guess. Here Im adding 3 buttons previous next and done button. flexible space and fixed space are used for spaces between buttons. Important to note here is the order that you adding your barbutton items. In your case use flexible space to place your 2 buttons on right and left end in the order of left end button, flexible space, right end button.
I've got the solution finally.
I am adding the ToolBar to the PickerView and then calling UIToolBar.SizeToFit() which is must in all cases.
the issue was I had to change the picker view size later in this case the size of subview ToolBar is not adapting with the new size coordination of pickerView. So the solution simply to call again ToolBar.SizeToFit() after any modification of parent view. here's snap of the code:
// popupView is custom UIPickerView
popupView.frame = CGRect(x:0, y:0, width:100, height:100)
// toolBar is an object of UIToolBar of the custom UIPickerView AddCurrencyPicker
(popupView as! AddCurrencyPicker).toolBar.sizeToFit()
I add a right navigation bar item that has a coloured background image:
let rightButton = UIBarButtonItem(image: UIImage(named: "avatar")!,
style: UIBarButtonItemStyle.Plain,
target: self,
action: #selector(self.rightNavBarItemAction))
navigationItem.rightBarButtonItem = rightButton
Instead of having the image as the background of the button (in colours), I get a white placeholder.
You can update the image's rendering mode to
UIImageRenderingMode.alwaysOriginal.
Swift 4.2:
let img = UIImage(named: "avatar")!.withRenderingMode(.alwaysOriginal)
let rightButton = UIBarButtonItem(image: img,
style: UIBarButtonItem.Style.Plain,
target: self,
action: #selector(self.rightNavBarItemAction))
Swift 4:
let img = UIImage(named: "avatar")!.withRenderingMode(.alwaysOriginal)
let rightButton = UIBarButtonItem(image: img,
style: UIBarButtonItemStyle.Plain,
target: self,
action: #selector(self.rightNavBarItemAction))
Swift 3:
let img = UIImage(named: "avatar")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal);
let rightButton = UIBarButtonItem(image: img,
style: UIBarButtonItemStyle.Plain,
target: self,
action: #selector(self.rightNavBarItemAction))
Alternatively you can set a custom view as in Vladimir's answer.
To achieve this you need a button UIButton, set the image of that button and then assigned it as the custom view if your UIBarButtonItem:
let button = UIButton()
button.frame = CGRectMake(0, 0, 51, 31)
button.setImage(UIImage(named: "avatar"), forState: .Normal)
button.addTarget(self, action: #selector(self.rightNavBarItemAction)), forControlEvents: .TouchUpInside)
let barButton = UIBarButtonItem()
barButton.customView = button
self.navigationItem.rightBarButtonItem = barButton
When I add a UIToolBar, it appears to be transparent. However, I do not want this to happen. Here is my code:
var done = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Done, target: self, action: Selector("done"))
if let font = UIFont(name: "Avenir", size: 17.0) {
done.setTitleTextAttributes([NSFontAttributeName: font], forState: .Normal)
}
toolBar.items = [done]
toolBar.barStyle = UIBarStyle.Default
self.birthdayTextField.inputAccessoryView = toolBar
Am I doing anything wrong?
Having come across this issue myself I found that the toolbar must either be instantiated with a non-zero frame, or have sizeToFit called on it.
e.g.
let tb = UIToolbar()
tb.translucent = false
tb.items = [UIBarButtonItem.init(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil), UIBarButtonItem.init(title: "A button", style: .Plain, target: self, action: Selector("someAction:"))]
tb.sizeToFit()
userField?.inputAccessoryView = tb
or
let tb = UIToolbar(CGRectMake(0,0,view.frame.width,44))
tb.translucent = false
tb.items = [UIBarButtonItem.init(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil), UIBarButtonItem.init(title: "A button", style: .Plain, target: self, action: Selector("someAction:"))]
userField?.inputAccessoryView = tb
try this code for UIToolBar Transparent :
self.toolbar.setBackgroundImage(UIImage(),
forToolbarPosition: UIBarPosition.Any,
barMetrics: UIBarMetrics.Default)
self.toolbar.setShadowImage(UIImage(),
forToolbarPosition: UIBarPosition.Any)
This should disable the translucency/transpacency effect
toolbar.translucent = false
Try this
toolBar.barStyle = UIBarStyle.Black
and make sure toolBar.translucent = false
In Xamarin (similar for swift)
toolbar.Translucent = false;
toolbar.BarTintColor = color;
I would like to have more than a single UIBarButtonItem on the right side of my UINavigationBar. How can I achieve this?
An example of what I am trying are shown below - you can notice that the top right has more than one button.
Use this in swift:
override func viewDidLoad() {
super.viewDidLoad()
let editImage = UIImage(named: "plus")!
let searchImage = UIImage(named: "search")!
let editButton = UIBarButtonItem(image: editImage, style: .Plain, target: self, action: "didTapEditButton:")
let searchButton = UIBarButtonItem(image: searchImage, style: .Plain, target: self, action: "didTapSearchButton:")
navigationItem.rightBarButtonItems = [editButton, searchButton]
}
Write the action functions like this:
func didTapEditButton(sender: AnyObject){
...
}
func didTapSearchButton(sender: AnyObject){
...
}
Swift 4 & 5
override func viewDidLoad() {
super.viewDidLoad()
let editImage = UIImage(named: "edit")!
let searchImage = UIImage(named: "search")!
let editButton = UIBarButtonItem(image: editImage, style: .plain, target: self, action: #selector(didTapEditButton(sender:)))
let searchButton = UIBarButtonItem(image: searchImage, style: .plain, target: self, action: #selector(didTapSearchButton(sender:)))
navigationItem.rightBarButtonItems = [editButton, searchButton]
}
#objc func didTapEditButton(sender: AnyObject){
}
#objc func didTapSearchButton(sender: AnyObject){
}
-(void)viewDidLoad{
UIBarButtonItem *anotherButton1 = [[UIBarButtonItem alloc] initWithTitle:#"Button_1" style:UIBarButtonItemStylePlain target:self action:#selector(button_1:)];
UIBarButtonItem *anotherButton2 = [[UIBarButtonItem alloc] initWithTitle:#"Button_" style:UIBarButtonItemStylePlain target:self action:#selector(button_2:)];
self.navigationItem.rightBarButtonItems=#[anotherButton1,anotherButton2];
}
In Swift 3 you can use:
let editImage = UIImage(named: "plus")!
let searchImage = UIImage(named: "search")!
let editButton = UIBarButtonItem(image: editImage, style: .plain, target: self, action: #selector(didTapEditButton))
let searchButton = UIBarButtonItem(image: searchImage, style: .plain, target: self, action: #selector(didTapSearchButton))
navigationItem.rightBarButtonItems = [editButton, searchButton]
I think nothing of the above is going to work
Try this
var burgerItem = UIBarButtonItem(image: UIImage(named:"categories"), style: .Plain, target: self, action: "categories")
var weatherItem = UIBarButtonItem(title: "Weather", style: .Plain, target: self, action: "weather")
burgerItem.tintColor = UIColor.whiteColor()
weatherItem.tintColor = UIColor.whiteColor()
navigationItem.setRightBarButtonItems([burgerItem,weatherItem], animated: true)
You have to use navigationItem.setRightBarButtonItems and be carefull. navigationItem has to be of a view controller.
class testViewController:UIViewController {
ovverride func viewDidLoad() {
self.navigationItem.setRightBarButtonItems(...
}
}
Simply add this code:
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]
This is the result:
With Swift 4
let editImage = UIImage(named: "toolbar_edit")!
let favoriteImage = UIImage(named: "toolbar_fav_solid")!
let editButton = UIBarButtonItem(image: editImage, style: .plain, target: self, action: #selector(didTapEditButton))
let favoriteButton = UIBarButtonItem(image: favoriteImage, style: .plain, target: self, action: #selector(didTapFavoriteButton))
navigationItem.rightBarButtonItems = [editButton, favoriteButton]
Click action for those buttons
#objc func didTapEditButton(sender: AnyObject) {
print("edit")
}
#objc func didTapFavoriteButton(sender: AnyObject) {
print("favorite")
}

Accepted answer as well as few of the answer is absolutely correct but in my case none of them work.
Reason : My View Controller was Inherited from UIViewController and I had to set Add to Cart Button and Search Button On Right hand side. And All my view controllers were a part of UITabbarController.
let editImage = UIImage(named: "OrdersTabIcon")
let searchImage = UIImage(named: "OrdersTabIcon")
let editButton = UIBarButtonItem(image: editImage, style: .plain, target: self, action: #selector(iconTapped))
let searchButton = UIBarButtonItem(image: searchImage, style: .plain, target: self, action: #selector(iconTapped))
Instead of using
self.navigationItem.setRightBarButtonItems([editButton, searchButton], animated: true)
Use This .
self.navigationController?.navigationBar.topItem?.setRightBarButtonItems([editButton, searchButton], animated: true)
This is may be help for you in objective-c,
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.navigationItem.title = #"Title";
UIBarButtonItem *logOutButton = [[UIBarButtonItem alloc] initWithTitle:#"Logout" style:UIBarButtonItemStylePlain target:self action:#selector(ButtonClickedAtIndex1:)];
[logOutButton setTintColor:[UIColor blackColor]];
logOutButton.tag = 1;
UIBarButtonItem *syncBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Sync" style:UIBarButtonItemStylePlain target:self action:#selector(ButtonClickedAtIndex1:)];
[syncBarButtonItem setTintColor:[UIColor blackColor]];
syncBarButtonItem.tag = 2;
self.navigationItem.leftBarButtonItem = logOutButton;
self.navigationItem.rightBarButtonItem = syncBarButtonItem;
float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
if (systemVersion >= 7.0) {
self.edgesForExtendedLayout = UIRectEdgeNone;
self.navigationController.navigationBar.translucent = NO;
}
}
return self;
}
Use navigationItem's rightBarButtonItems, which takes an array of UIBarButton. Appledoc
let share = UIBarButtonItem(barButtonSystemItem: .action, target: self, action: #selector(shareTapped))
let add = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(addTapped))
navigationItem.rightBarButtonItems = [add, share]
I don't know wether an Interface Builder solution was not possible before, but at least with the most recent update (Xcode 11.0), it is possible to drag two UI Bar Buttons into the rightBarButton space. Two outlets and actions can then be dragged into the code like always.
Since the OP didn't ask for a solution without IB, I think this also qualifies as an answer.
For Xamarin iOS with the new updates, it is like:
UIBarButtonItem Button1 = new UIBarButtonItem(UIImage.FromBundle("Image1"), UIBarButtonItemStyle.Plain,YourEventHandler);
UIBarButtonItem Button2 = new UIBarButtonItem(UIImage.FromBundle("Image1"), UIBarButtonItemStyle.Plain,YourEventHandler);
NavigationItem.SetRightBarButtonItems(new[]{ Button1, Button2 }, true);
