Swift - Call UIToolBar by buttonClick Event - swift

Question

In my viewController there are one button and textField. When use click on textField it fires didBeginEdit event and i can call a toolbar.
This is my view :
MyView
When user click on textField it seems like below :
textFieldClicked
And My Swift code is below :
Class ViewController: UIViewController {
#IBAction func btn(sender: AnyObject) {
// i want to call ToolBar here ...
}
#IBOutlet weak var textFieldOutlet: UITextField!
#IBAction func txtFieldBeginEdit(sender: AnyObject) {
raiseToolBar(textFieldOutlet)
}
var datePicker : UIDatePicker!
let ToolBar = UIToolbar()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
func raiseToolBar(textField : UITextField)
{
self.datePicker = UIDatePicker(frame: CGRectMake(0,0,UIScreen.mainScreen().bounds.height , UIScreen.mainScreen().bounds.height / 3))
self.datePicker.backgroundColor = UIColor.whiteColor()
self.datePicker.datePickerMode = .Date
textField.inputView = self.datePicker
ToolBar.barStyle = .Default
ToolBar.translucent = true
ToolBar.tintColor = UIColor(red : 92/255, green : 216/255 ,blue : 255/255, alpha: 1 )
ToolBar.sizeToFit()
let done = UIBarButtonItem(title: "Tamam" , style: .Plain , target: self, action: #selector(ViewController.doneClick))
let space = UIBarButtonItem(barButtonSystemItem: .FlexibleSpace, target : nil , action: nil)
let cancel = UIBarButtonItem(title: "İptal" , style: .Plain , target: self, action: #selector(ViewController.cancelClick))
ToolBar.setItems([done , space , cancel], animated: true)
ToolBar.userInteractionEnabled = true
textField.inputAccessoryView = ToolBar
}
func doneClick() {
}
func cancelClick() {
}
}
At this point there is no problem. Bu i want to call this UIToolBar by clic on the button(named btn). Under btnClick event i tried to send empty textField to raiseToolBar method but it also don't work. How can i edit my code to call ToolBar by buttonClick
**************** edit *****************
textFieldOutlet.becomeFirstResponder()
raiseToolBar(textFieldOutlet)
i solve like above. is it a clear way ?

You can assign first responder to your text field like this inside your btn action:
textFieldOutlet.isFirstResponder = true
