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

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 am trying to add a Cancel UIBarButtonItem to my navigation bar using following code:
func setupNavBar() {
self.navBar = UINavigationBar(frame: CGRectMake(0.0, 0.0, UIScreen.mainScreen().bounds.width, 64.0))
let customNavigationItem = UINavigationItem(title: "Connect Accounts")
let cancelButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Cancel, target: self, action: "cancelClicked")
customNavigationItem.setLeftBarButtonItem(cancelButton, animated: true)
self.navBar.setItems([customNavigationItem], animated: true)
self.view.addSubview(self.navBar)
}
The bar button is appearing completely sticked to the screen edge as follow:
Why is this button appearing sticked to the edge of screen and how can I give it spacing so that it does not sticks there? Please help!
EDIT: My button is sticked to just left edge of screen and not to the top-left corner.
The correct way to add space is using .FixedSpace :
let fixedSpace = UIBarButtonItem(barButtonSystemItem: .FixedSpace, target: nil, action: nil)
fixedSpace.width = 10
customNavigationItem.leftBarButtonItems = [fixedSpace, cancelButton]
UIBarButtonSystemItemFixedSpace
Blank space to add between other
items. Only the width property is used when this value is set.
Available in iOS 2.0 and later.
Try this
let btn = UIButton(frame: CGRectMake(<your margin>, 0, 50, 44))
btn.setTitle("Cancel", forState: UIControlStateNormal)
let btnbarButton = UIBarButtonItem(customView: btn)
customNavigationItem.setLeftBarButtonItem(btnbarButton, animated: true)
Try it.
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.setupNavBar()
}
func setupNavBar() {
let navBar = UINavigationBar(frame: CGRectMake(0.0, 0.0, UIScreen.mainScreen().bounds.width, 64.0))
let customNavigationItem = UINavigationItem(title: "Connect Accounts")
let cancelButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Cancel, target: self, action: "cancelClicked:")
let fixedSpace = UIBarButtonItem(barButtonSystemItem: .FixedSpace, target: nil, action: nil)
fixedSpace.width = 10
customNavigationItem.leftBarButtonItems = [fixedSpace, cancelButton]
navBar.setItems([customNavigationItem], animated: true)
self.view.addSubview(navBar)
}
func cancelClicked(sender: AnyObject){
print("Good luck!")
}
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]()
In my app when user clicks on UITextField he should be able to pick up a value from UIPickerView OR enter his own value using keyboard.
What's the best way of doing it in terms of user experience and ease of implementation?
UIPickerView with toolbar is already implemented.
I'd appreciate both advice on best way of doing it and example code of switching keyboard <-> pickerview.
I've tried adding a button "Show keyboard" on pickerview's toolbar and adding the following code:
func showKeyboard() {
selectedTextField.inputView = nil
}
But clicking this button doesn't do anything. Also I'm not sure it's a good way in terms of UX.
Here's the solution:
var useKeyboard:Bool = true
func showKeyboard() {
if useKeyboard {
useKeyboard = false
selectedTextField.inputView = nil
selectedTextField.reloadInputViews()
selectedTextField.keyboardAppearance = UIKeyboardAppearance.Default
selectedTextField.keyboardType = UIKeyboardType.Default
} else {
useKeyboard = true
selectedTextField.inputView = nil
selectedTextField.reloadInputViews()
createPicker(selectedTextField)
selectedTextField.resignFirstResponder()
selectedTextField.becomeFirstResponder()
}
}
// That's my custom picker - adjust whatever you need
func createPicker(sender: UITextField){
selectedTextField = sender
// Create picker view
var newPickerView: UIPickerView
newPickerView = UIPickerView(frame: CGRectMake(0, 200, view.frame.width, 300))
newPickerView.backgroundColor = .whiteColor()
// Only for UIPickerView
newPickerView.showsSelectionIndicator = true
newPickerView.delegate = self
newPickerView.dataSource = self
// Create toolbar
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()
// Create buttons
var doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Plain, target: self, action: "donePicker")
var spaceButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
var cancelButton = UIBarButtonItem(title: "Cancel", style: UIBarButtonItemStyle.Plain, target: self, action: "cancelPicker")
var customButton = UIBarButtonItem(title: "Keyboard", style: UIBarButtonItemStyle.Plain, target: self, action: "showKeyboard")
// Assign buttons to toolbar
toolBar.setItems([cancelButton, spaceButton, customButton, doneButton], animated: false)
toolBar.userInteractionEnabled = true
// Add pickerview and toolbar to textfield
sender.inputView = newPickerView
sender.inputAccessoryView = toolBar
}
func donePicker() {
useKeyboard = true
selectedTextField.resignFirstResponder()
}
func cancelPicker() {
useKeyboard = true
selectedTextField.resignFirstResponder()
}
