Question

I create a button with a popover date picker. Inside the date picker, I control dragged an IBAction to receive the date I pick and print out. However, whenever I select another date, it will always print out twice. (Select the same day will print out once)

I would like to get ONE value from date picker whenever I select. How can I fix it?

here is what I've done.

Try adding this in awakeFromNib or viewDidLoad :

    let theAction = Int(NSEventMask.MouseExitedMask.rawValue)
    theDatePicker.sendActionOn(theAction)
