无法在Swift中将Anyobject转换为NSString

Question

There's an exception when I run it.

self.year = value as! NSString 

Exception:

 Could not cast value of type '__NSDate' (0x1051bd6a0) to 'NSString' (0x10564d8e0).

What am I missing ?

var  datePicker = ActionSheetDatePicker(title: "Date:",datePickerMode: UIDatePickerMode.Date, selectedDate: NSDate(),doneBlock: { 

   picker, value, index in

   self.year = value as! NSString 

   println("year = \(year)")
   println("value = \(value)")

   return
   }, cancelBlock: { ActionStringCancelBlock in return }, origin: sender.superview!.superview)

I think you have to convert date to string via your selected value

let formatter: DateFormatter = DateFormatter()
formatter.dateFormat = "yyyy-MM-dd-HH-mm-ss"
let dateStr: String = formatter.string(from: value as! Date)

You can use any other format like : "yyyy" or "HH:mm:ss" etc.

and set it to your year variable

self.year = dateStr
