ios - 无法分配类型UIDatePicker的值来键入字符串？ swift 2.2

我在“AvailableDayTextField.text = datePicker”行中遇到此错误

@IBOutlet var AvailableDayTextField: UITextField!
let datePicker = UIDatePicker()

func createDatePicker(){
    let toolbar = UIToolbar()
    toolbar.sizeToFit()
    let doneButton = UIBarButtonItem(barButtonSystemItem: .done , target: nil , action: nil)
    toolbar.setItems([doneButton], animated: false)
    AvailableDayTextField.text = datePicker
}

在您的ViewDidLoad集上，类似于

 datePicker.date = NSDate()
datePicker.datePickerMode = .Date
datePicker.addTarget(self, action: #selector(self.dateTextField), forControlEvents: .ValueChanged)
AvailableDayTextField.inputView = datePicker

并将函数作为

func dateTextField(sender: AnyObject) {
var picker = (AvailableDayTextField.inputView as! UIDatePicker)
picker.maximumDate = NSDate()
var dateFormat = NSDateFormatter()
var eventDate = picker.date
dateFormat.dateFormat = "dd/MM/yyyy"
var dateString = dateFormat.stringFromDate(eventDate)
AvailableDayTextField.text = "\(dateString)"
}
