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 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:

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 have to use
[addButton,addButton,addButton,addButton,addButton,addButton,addButton]
to put addButton to right side of the bar. What is the correct way?
func addBtnToKeyboardTop() {
let keyboardToolbar = UIToolbar()
keyboardToolbar.sizeToFit()
keyboardToolbar.isTranslucent = false
keyboardToolbar.barTintColor = UIColor.lightGray
let addButton = UIBarButtonItem(
barButtonSystemItem: .done,
target: self,
action: #selector(CreateClubTVC.hideKeyboard)
)
addButton.tintColor = UIColor.black
keyboardToolbar.items = [addButton,addButton,addButton,addButton,addButton,addButton,addButton]
membershipFee.inputAccessoryView = keyboardToolbar
}
For that you have to add a flexible space before the button.
Swift 3
let keyboardToolbar = UIToolbar()
keyboardToolbar.sizeToFit()
//creating flexible space
let flexibleSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
// creating button
let addButton = UIBarButtonItem(barButtonSystemItem: .done, target: self, action: #selector(CreateClubTVC.hideKeyboard))
// adding space and button to toolbar
keyboardToolbar.setItems([flexibleSpace,addButton], animated: false)
// adding toolbar to input accessory view
membershipFee.inputAccessoryView = keyboardToolbar
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 have a UIPickerView and I am adding a UIToolBar with 2 UIBarButtonItems to it.
var toolBar = UIToolbar()
toolBar.frame.origin.y = -40
toolBar.barStyle = UIBarStyle.Default
toolBar.translucent = true
toolBar.tintColor = UIColor(red: 76/255, green: 217/255, blue: 100/255, alpha: 1)
toolBar.sizeToFit()
var doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Bordered, target: self, action: "donePicker")
var spaceButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
var cancelButton = UIBarButtonItem(title: "Cancel", style: UIBarButtonItemStyle.Bordered, target: self, action: "canclePicker")
toolBar.setItems([cancelButton, spaceButton, doneButton], animated: false)
toolBar.userInteractionEnabled = true
pickerView.addSubview(toolBar)
pickerView.bringSubviewToFront(toolBar)
view.bringSubviewToFront(toolBar)
The problem is, that when I try to click on the the UIBarButtonItem, it doesn't fire, it doesn't even recognize it, it just clicks the cell beneath it.
Can you try this codes.
var textField = UITextField(frame: CGRectMake(20, 50, view.width - 40, 30))
textField.backgroundColor = UIColor.redColor()
view.addSubview(textField)
var pickerView = UIPickerView(frame: CGRectMake(0, 200, view.width, 300))
pickerView.backgroundColor = UIColor.whiteColor()
pickerView.showsSelectionIndicator = true
var toolBar = UIToolbar()
toolBar.barStyle = UIBarStyle.Default
toolBar.translucent = true
toolBar.tintColor = UIColor(red: 76/255, green: 217/255, blue: 100/255, alpha: 1)
toolBar.sizeToFit()
var doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Bordered, target: self, action: "donePicker")
var spaceButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
var cancelButton = UIBarButtonItem(title: "Cancel", style: UIBarButtonItemStyle.Bordered, target: self, action: "canclePicker")
toolBar.setItems([cancelButton, spaceButton, doneButton], animated: false)
toolBar.userInteractionEnabled = true
textField.inputView = pickerView
textField.inputAccessoryView = toolBar
I believe that you need to raise the picker and toolbar using the standard UIResponder mechanism or cheat by using a hidden UITextField to get the same result.
