Property:
A new array containing the dictionary’s values, or an empty array if the dictionary has no entries (read-only)

dict.allValues = [{
group = "\U5176\U4ed6";
groupid = 5;
lastactivity = 0;
uid = 196186;
username = "\U9093\U6c5f\U6d32";
}]

valueDict = {
group = "\U5176\U4ed6";
groupid = 5;
lastactivity = 0;
uid = 196186;
username = "\U9093\U6c5f\U6d32";
}

二，計算機的完全匹配。

let model = FriendModel()

            model.setValuesForKeysWithDictionary(transformDict)

model 的屬性 ，
必須與transformDict 的keys ,
一一對應，不缺不漏。

var group: String?
var groupid: String?

var uid: String?
var username: String?




var lastactivity: String?

2016___Find：
類型也要一一對應。完全吻合

var group: String?
var groupid: NSNumber?    //String?

var uid: NSNumber?   //String?
var username: String?




var lastactivity: NSNumber?   //String?
