ios - swift SwiftyJSON 无法设置对象

Question

var petArray: JSON!

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.

    var tmp: NSMutableArray!
    tmp = NSMutableArray()
    tmp.addObject(["name":"pet01", "age":15, "type":"dog", "breed":"QQ", "size":"small", "comment":"qqqq", "selected":0]);
    tmp.addObject(["name":"pet02", "age":15, "type":"dog", "breed":"QQ", "size":"small", "comment":"wwww", "selected":0]);

    petArray = JSON(tmp)

    petArray[0]["name"] = JSON("QQQQ") //why cannot update????

    print(petArray)
}

我尝试更新第一个索引处的名称，但没有用

如果有什么问题吗？

您必须在转换为 JSON 之前更新它。
