Add toolbar with done and cancell for datepicker iOS swift

Problem: 

Want to create a date picker for textfield while tap show date picker with done and cancel buttons with action.

Solution:

                    let toolBar = UIToolbar()

                    toolBar.sizeToFit()

                    let doneBtn = UIBarButtonItem(barButtonSystemItem: .done, target: nil, action: #selector(doneAction))

                    let cancelBtn = UIBarButtonItem(barButtonSystemItem: .cancel, target: nil, action: #selector(cancelAction))

                    let spaceBtn = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action:nil)

                    myTF.inputAccessoryView = toolBar

                    myTF.inputView = datePicker

    // MARK: - Done action

    @objc func doneAction() {

        self.view.endEditing(true)

}

    // MARK: - cancel action

    @objc func cancelAction() {

        self.view.endEditing(true)

    }
