ios - PFObject 无法转换

Question

然后我尝试将键从 PFObject 转换为字符串，但出现错误。我在 Parses 网站上找不到任何内容。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

我认为这是你必须做的，试试这个:

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

此后您不应该收到错误。

祝你好运!
