Question

我正在使用iOS 9和Swift 2以及Parse。我有一个像下面那样的PF对象，提前创建并从解析中拉下来。

＆＃13;

 {
   "history" = [
     {
       "completed": false,
       "date": "December 1, 2015",
       "id": "dlxIHMO4lgDecember 1, 201507:15:06"
     }
   ],
   "user" = "john doe"
}

＆＃13;

我正在尝试将completed属性更新为true并保存。

var daily = PFObject(className: "Drops")
let query = PFQuery(className: "Drops")
query.whereKey("username", equalTo: PFUser.currentUser()!)
query.getFirstObjectInBackgroundWithBlock {
  (object: PFObject?, error: NSError?) -> Void in
    if error != nil || object == nil {
      print("The getFirstObject request failed.")
    } else {
      print("Successfully retrieved the object")
      daily = object!
      (daily["history"][0]).setValue(true, forKey: "completed")

      daily.saveInBackgroundWithBlock {
        (success: Bool, error: NSError?) -> Void in
          if (success) {
            print("completion saved in parse")
          } else {
            print("completion could not be saved in parse")
          }
      }
    }
}

在调试时，属性值看起来更新，但在解析时它显示旧值false。

我不确定我错过了什么！我还尝试使用daily.saveEventually()但没有成功。
