iOS Swift 2.0 Done Button - ios

I'm trying to add a Done button to a keyboard. The code below used to work:
func addDoneButtonOnKeyboard()
{
let doneToolbar: UIToolbar = UIToolbar(frame: CGRectMake(0, 0, screenWidth, 50))
//doneToolbar.barStyle = UIBarStyle.BlackTranslucent
let flexSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
let done: UIBarButtonItem = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Done, target: self, action: Selector("doneButtonAction"))
var items: [UIBarButtonItem]?
items?.append(flexSpace)
items?.append(done)
doneToolbar.items = items
doneToolbar.sizeToFit()
commentsField.inputAccessoryView=doneToolbar
}
It puts the toolbar above the keyboard but there is no done button.

The issue comes from the line
var items: [UIBarButtonItem]?
Your array of UIBarButtonItem is never initialized. Replace this line with
var items: [UIBarButtonItem]? = [UIBarButtonItem]()

Keyboard (numpad) toolbar working but not showing

I tried to add a toolbar for my UITextFiled, the keyboard is set to numpad. It is working but the button is not showing. I created an extension for my UITextfield
extension UITextField {
/// Adding a done button on the keyboard
func addDoneButtonOnKeyboard() {
let doneToolbar = UIToolbar(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 50))
doneToolbar.barStyle = .default
let flexSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
let done = UIBarButtonItem(title: "Done", style: .done, target: self, action: #selector(self.doneButtonAction))
let items = [flexSpace, done]
doneToolbar.items = items
doneToolbar.sizeToFit()
self.inputAccessoryView = doneToolbar
}
/// Done button callback
#objc func doneButtonAction() {
self.resignFirstResponder()
}
}
and then I am calling this extension like this
private lazy var fromInputField: CoinpassInput = {
let input = CoinpassInput()
input.keyboardType = .decimalPad
input.addTarget(self, action: #selector(fromInputFieldDidChange), for: .editingChanged)
input.addDoneButtonOnKeyboard()
return input
}()
the toolbar is showing and working but the 'done; button is not showing. If I click on the right corner of the toolbar. the keyboard will hide. I dont know what I am missing why the button is not showing.
Try this code, with slight modifications:
func addDoneButtonOnKeyboard() {
let doneToolbar = UIToolbar(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 50))
doneToolbar.barStyle = .default
doneToolbar.barTintColor = .red
let flexSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
let done = UIBarButtonItem(title: "Done", style: .done, target: self, action: #selector(self.doneButtonAction))
done.tintColor = .yellow
doneToolbar.setItems([flexSpace,done], animated: false)
doneToolbar.isUserInteractionEnabled = true
self.inputAccessoryView = doneToolbar
}

iOS toolbar barbuttonitem spacer

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()

How to add UIBarButtonItem to right side of UIToolBar?

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

How to add background Image to a UIBarButtonItem

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)

Swift: inputAccessoryView buttons are not showing

Following is my code for adding an inputAccessoryView (with a Done button on it) to my textView:
let keyboardButtonView = UIToolbar()
keyboardButtonView.sizeToFit()
let doneButton = UIBarButtonItem(image: nil, style: .Done, target: self, action: "closeMessageViewKeyboard")
doneButton.possibleTitles = ["Done"]
var toolbarButtons = NSMutableArray()
toolbarButtons.addObject(doneButton)
keyboardButtonView.items = toolbarButtons as [AnyObject]
messageView.inputAccessoryView = keyboardButtonView
The Done button never appears. All I get is a white accessory bar. Am I missing anything here?
For me I create the accessory view using UINavigationBar like this:
let navBar = UINavigationBar(frame: CGRectMake(0, 0, viewWidth, 44))
navBar.barStyle = UIBarStyle.BlackTranslucent;
navBar.backgroundColor = UIColor.blackColor();
navBar.alpha = 0.9;
//replace viewWidth with view controller width
let navItem = UINavigationItem()
let doneButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Done, target: self, action: "closeMessageViewKeyboard")
navItem.rightBarButtonItem = doneButton
navBar.pushNavigationItem(navItem, animated: false)
messageView.inputAccessoryView = navBar
1) Add self?
self.messageView.inputAccessoryView = keyboardButtonView
2) You should be able to remove this line:
doneButton.possibleTitles = ["Done"]
and add (title: "done",...) to the line above it.
3) I have similar code and it probably doesn't matter, but, you might add:
keyboardButtonView.barStyle = UIBarStyle.Default
