PFObject无法转换

Question

然后我尝试将一个键从 PFObject 转换为一个字符串，它给我一个错误。我在 Parses 网站上找不到任何东西。请帮忙

var findProgram = PFQuery(className: "Programs")

findProgram.getObjectInBackgroundWithId(data["program"] as! String!, block: { (object: PFObject?, error) -> Void in
      if error == nil {

          var objects = object["name"] as! String

          print(objects)

          self.programUpdated.append(object?.createdAt as NSDate!)

          }

})

Answer 1

我想这就是你要做的，试试这个：

//explicitly giving the objects var a type of String
var objects:String = object["name"] as! String

在那之后你不应该得到一个错误。

祝你好运！

Answer 2

我认为这将是更好的方法：

if let objects = object?.objectForKey("name") as? String{

    print(objects)
    self.programUpdated.append(objects?.createdAt as NSDate!)
}
