How to save image in NSUserDefault?

Ans : 

NSUserDefault support format NSData for save. So convert image into NSData and then save.

Save image in NSUserDefault :

    let defaults = NSUserDefaults.standardUserDefaults()

   var imgData = UIImageJPEGRepresentation(image, 1)

   defaults.setObject(imgData, forKey: "image")

Get image from NSUserDefault :

    let defaults = NSUserDefaults.standardUserDefaults()

      if let imgData = defaults.objectForKey("image") as? NSData

      {

         if let image = UIImage(data: imgData)

           {

               self.imageView.image = image

           }

      }
