ios - 显示字典数组的问题

Question

我有一个像这样声明的字典 var arrayOfDictionary = [[:]]。现在我的 tableviewcell 中有一些数据，如 rate、id 等。我将这些值存储在字典中，就像在 cellForRowAt 中一样...

    var dictionary = ["id": "", "quantity": "","sellingPrice":""] as [String : Any]
    dictionary["id"] = product?.id
    dictionary["quantity"] = product?.quantity
    dictionary["sellingPrice"] = product?.theRate
    arrayOfDictionary.append(dictionary)

现在，当我打印 arrayOfDictionary 时，我得到类似这样的东西......

[[:], [AnyHashable("id"): "5", AnyHashable("sellingPrice"): "499", AnyHashable("quantity"): "-1"], [AnyHashable("id"): "8", AnyHashable("sellingPrice"): "500", AnyHashable("quantity"): "79"], [AnyHashable("id"): "8", AnyHashable("sellingPrice"): "500", AnyHashable("quantity"): "79"]]

即3个产品的id、数量和费率。但我不想要这种格式，而是我想要第一组 id、rate 和 quantity 一组，第二组id、rate 和 quantity 在另一个组中等等..

简而言之，我希望它们采用这种格式...

[{"remaining_balance":"0.0","shipping_charges":0, "grand_total":320,"product_id”:”4”}, {"remaining_balance”:”1.0”,”shipping_charges”:200, "grand_total”:456,”product_id”:”5”}]

别担心，这也是一个字典数组，但您对 JSON 打印格式和字典打印格式数组感到困惑:

[[:], [AnyHashable("id"): "5", AnyHashable("sellingPrice"): "499", AnyHashable("quantity"): "-1"], [AnyHashable("id"): "8", AnyHashable("sellingPrice"): "500", AnyHashable("quantity"): "79"], [AnyHashable("id"): "8", AnyHashable("sellingPrice"): "500", AnyHashable("quantity"): "79"]]

这是你数组中的字典:

[AnyHashable("id"): "5", AnyHashable("sellingPrice"): "499", AnyHashable("quantity"): "-1"],

你可以通过迭代来验证它:

for dict in arrayOfDictionary {
    print(dict)
}

编辑

var arrayOfDictionary = [[String:Any]]()
var dictionary = ["id": "", "quantity": "","sellingPrice":""] as [String : Any]
    dictionary["id"] = product?.id
    dictionary["quantity"] = product?.quantity
    dictionary["sellingPrice"] = product?.theRate
    arrayOfDictionary.append(dictionary)

let data = try! JSONSerialization.data(withJSONObject: arrayOfDictionary, options: .prettyPrinted)
print(data)
let json = NSString(data: data, encoding: String.Encoding.utf8.rawValue)
print(json)
