使用Swift在UIActionsheet中添加datepicker

有没有办法从UIAlertControllerStyle.ActionSheet呈现日期选择器？有办法在ActionSheet中添加按钮并向这些按钮添加操作,但我找不到在ActionSheet中添加datepicker或任何自定义视图的解决方案.

解决方法

这是不可能的,但是当用户单击文本字段时,您可以使用UItextfield输入视图和附件视图来显示和关闭日期选择器

class KPDatePickerViewController: UIViewController {
    var datePicker:UIDatePicker!
    @IBOutlet var dateTextField:UITextField!

    override func viewDidLoad() {
        var customView:UIView = UIView (frame: CGRectMake(0,100,320,160))
        customView.backgroundColor = UIColor.brownColor()
        datePicker = UIDatePicker(frame: CGRectMake(0,160))
        customView .addSubview(datePicker)
        dateTextField.inputView = customView
        var doneButton:UIButton = UIButton (frame: CGRectMake(100,44))
        doneButton.setTitle("Done",forState: UIControlState.normal)
        doneButton.addTarget(self,action: "datePickerSelected",forControlEvents: UIControlEvents.TouchUpInside)
        doneButton.backgroundColor = UIColor .blueColor()
        dateTextField.inputAccessoryView = doneButton
    }

    func datePickerSelected() {
        dateTextField.text =  datePicker.date.description
    }
}
