Question

我将所选数据从列表传递到具有相应内容的模型类。我有itemName和itemPrice以及itemDescription，我将其传递给类中的模型变量并访问另一个类中的模型变量。现在我想从该模型中获取值并将其作为参数传递给服务。我在我的参数中有一些键，我想传递这些值，值是动态的。这是我的模型类，

class Item : NSObject {
var totalPrice : String?
var numberOfItems : Int = 1
var itemPrice : String?
var itemName : String?
var itemID : String?
var itemId : String?
var  itemDdescription : String?
}

class ItemDataSource : NSObject {
var items = [Item]()
static let sharedInstance = ItemDataSource()
private override init() {}
}

这就是我在模型中传递值的方式，

 let item = Item()
    item.totalPrice = String(result)
    item.itemPrice = String(result)
    item.itemDdescription = itemDescription
    item.itemName = itemName
    item.itemID = itemID
    item.itemId = itemId
    ItemDataSource.sharedInstance.items.append(item)

这是我的服务中的参数格式，

 "cart": [
            [
                "childs": [
                    [
                        "addon_cat_id": "0",
                        "id": ItemDataSource.sharedInstance.items[0].itemId!,
                        "name": ItemDataSource.sharedInstance.items[0].itemName!,
                        "next_move_id": "",
                        "price": ItemDataSource.sharedInstance.items[0].itemPrice!,
                        "sort_order": "",
                        "type": "string"
                    ]
                ],
                "name": ItemDataSource.sharedInstance.items[0].itemName!,
                "price": ItemDataSource.sharedInstance.items[0].itemPrice!,
                "productid": ItemDataSource.sharedInstance.items[0].itemId!,
                "qty": 2,
                "description": ItemDataSource.sharedInstance.items[0].itemDdescription!
            ]
        ],

我想从我的模型类中传递参数中的所有内容，并且值应该在参数中找到它们各自的键。我很困惑，我怎么能在各自的键中传递它，当我通过这里时index 0它只向我的参数中的子项传递0个索引值。我如何通过我的模型类中的所有东西？如果我的模型类中有两个项目，当我将数据传递给它时，它应该在我的参数中生成两个子项.Chid是一个参数中的数组。如何做到这一点？

你可以试试这个：

class Item : NSObject {
    var totalPrice : String?
    var numberOfItems : Int = 1
    var itemPrice : String?
    var itemName : String?
    var itemID : String?
    var  itemDdescription : String?
}

class ItemDataSource : NSObject {
    var items = [Item]()
    static let sharedInstance = ItemDataSource()
    private override init() {}
}
var result = 20
var itemDescription = "itemDescription"
var itemName = "itemName"
var itemID = "1"

let item = Item()
item.totalPrice = String(result)
item.itemPrice = String(result)
item.itemDdescription = itemDescription
item.itemName = itemName
item.itemID = itemID
ItemDataSource.sharedInstance.items.append(item)

let noOFItems = ItemDataSource.sharedInstance.items.count

var dict = [Dictionary<String, Any>]()


for i in 0 ..< noOFItems {


    var child: [String: Any] = ["addon_cat_id": "0",
                                "id": ItemDataSource.sharedInstance.items[i].itemID!,
                                "name": ItemDataSource.sharedInstance.items[i].itemName!,
                                "next_move_id": "",
                                "price":ItemDataSource.sharedInstance.items[i].itemPrice!,
                                "sort_order": "",
                                "type": "string"]

    var childs:[String: Any] = ["childs": child, "name": ItemDataSource.sharedInstance.items[i].itemName!,
                                "price": ItemDataSource.sharedInstance.items[i].itemPrice!,
                                "productid": ItemDataSource.sharedInstance.items[i].itemID!,
                                "qty": 2,
                                "description": ItemDataSource.sharedInstance.items[i].itemDdescription!]

    dict.append(childs)

}

let cart = ["cart": dict]
print(cart)

从Swift中的模型类中提取值
