UIDatePicker on button tap

Question

So far I've only found date-picker bound to UITextField, but I need a date-picker which opens on UIButton tap in the same way as it does with the UITextField.

Is it possible? And if so, how? Thanks in advance.

Answer 1

@IBAction func BtnClicked(sender: AnyObject) {
    var picker : UIDatePicker = UIDatePicker()
    picker.datePickerMode = UIDatePickerMode.Date
    picker.addTarget(self, action: "dueDateChanged:", forControlEvents: UIControlEvents.ValueChanged)
    var pickerSize : CGSize = picker.sizeThatFits(CGSizeZero)
    picker.frame = CGRectMake(0.0, 250, pickerSize.width, 460)
    // you probably don't want to set background color as black
    // picker.backgroundColor = UIColor.blackColor()
    self.view.addSubview(picker)
}

func dueDateChanged(sender:UIDatePicker){
    var dateFormatter = NSDateFormatter()
    dateFormatter.dateStyle = NSDateFormatterStyle.LongStyle
    dateFormatter.timeStyle = NSDateFormatterStyle.NoStyle
    self.myLabel.text = dateFormatter.stringFromDate(dueDatePickerView.date)
}
