在我的应用程序中，我第一次使用AlamofireObjectMapper。所以我在一个类中映射api响应数据，然后我想使用这些数据。这是我的代码，我如何映射对象
extension OrderListViewController
{
func get_order_list()
{
let url = "(OrderURL)get_New_order_byPharmacy"
let param : [String : AnyObject] = [
"pharmacyId" : "131"
]
Alamofire.request(.GET, url, parameters: param, encoding: .URL).responseObject { (response:Response<OrderList, NSError>) in
let OrderList = response.result.value
print(OrderList!.Message)
}
}
}
这是我保存数据的类
class OrderList: Mappable {
var Message : String!
var Status : Int!
var result:[OrderResult]?
required init?(_ map: Map){
}
func mapping(map: Map) {
Message <- map["Message"]
Status <- map["Status"]
result <- map["Result"]
}
}
现在在我的OrderListViewController中，我想使用这些数据，那么我该如何使用这些数据呢？？
class OrderListViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {
@IBOutlet weak var table_OrderList: UITableView!
override func viewDidLoad() {
slideMenuController()?.addLeftBarButtonWithImage(UIImage(named: "ic_menu_black_24dp")!)
slideMenuController()?.addRightBarButtonWithImage(UIImage(named: "ic_notifications_black_24dp")!)
get_order_list()
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell : OrderList_Cell = tableView.dequeueReusableCellWithIdentifier("OrderList_Cell") as! OrderList_Cell
return cell
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 20
}
}
例如，我想在表视图单元格标签中打印消息值。那么，我如何从OrderList中获取该值呢？
谢谢slava，它给了我一些解决方案。但是我的json响应给了我数组。那么我该怎么办呢？我想以数组的数量返回。Set cion是数组的计数，那么我该怎么做呢。请看我最新的问题。
这是我的api响应。
{
"Status": 1,
"Message": "records are available",
"Result": [
{
"id": 30162,
"status_id": 2,
"status_type": "New Order",
"created_date": "2016-05-11T10:45:00.6779848",
"created": "11 May 2016"
},
{
"id": 30170,
"status_id": 2,
"status_type": "New Order",
"created_date": "2016-05-12T07:01:00.6968385",
"created": "12 May 2016"
},
{
"id": 30171,
"status_id": 2,
"status_type": "New Order",
"created_date": "2016-05-12T09:12:53.5538349",
"created": "12 May 2016"
},
{
"id": 30172,
"status_id": 2,
"status_type": "New Order",
"created_date": "2016-05-12T09:46:09.4329398",
"created": "12 May 2016"
},
{
"id": 30173,
"status_id": 2,
"status_type": "New Order",
"created_date": "2016-05-12T11:26:58.3211678",
"created": "12 May 2016"
},
{
"id": 30178,
"status_id": 2,
"status_type": "New Order",
"created_date": "2016-05-16T07:34:19.9128517",
"created": "16 May 2016"
}
]
}
控制器中需要一个局部变量来存储所有接收到的信息，这些信息将用于填充表。应该这样做：
class OrderListViewController: ... {
private var orderList: OrderList? // <- the local variable needed
...
}
extension OrderListViewController {
func get_order_list() {
...
Alamofire
.request(...)
.responseObject { (response:Response<OrderList, NSError>) in
switch response.result {
case .Success(let value):
self.orderList = value // <- fill the local variable with the loaded data
self.tableView.reloadData()
case .Failure(let error):
// handle error
}
}
}
...
}
extension OrderListViewController: UITableViewDataSource {
...
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell : OrderList_Cell = tableView.dequeueReusableCellWithIdentifier("OrderList_Cell") as! OrderList_Cell
// I assume 'OrderList_Cell' class has outlet for status type named 'statusTypeLabel' and OrderResult.statusType is of type String
if let orderList = orderList, orderResults = orderList.result {
cell.statusTypeLabel.text = orderResults[indexPath.row].statusType // <- use of the locally stored data
}
return cell
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if let orderList = orderList, orderResults = orderList.result {
return orderResults.count
} else {
return 0
}
}
}
注意：如果您从后端接收到JSON中的单个对象，那么代码应该是正确的。如果后端发送对象数组，则需要使用数组来存储本地数据（private var listOfOrderLists: [OrderList]），而使用Alamofire.request(...).responseArray(...)。但是关于局部变量的概念仍然是一样的。
typealias FailureHandler = (error: AnyObject) -> Void
typealias SuccessHandler = (result: AnyObject) -> Void
class WebServiceManager: NSObject {
class func getDataFromService(mehodName:String,success:(result:AnyObject)->(), apiError:(FailureHandler))
{
let url = "(OrderURL)get_New_order_byPharmacy"
let param : [String : AnyObject] = [
"pharmacyId" : "131"
]
alamoFireManager!.request(.GET, url)
.responseJSON { response in
print(response.response!)
print(response.result)
CommonFunctions.sharedInstance.deactivateLoader()
switch response.result {
case .Success(let JSON):
print("Success with JSON: (JSON)")
guard let _ = JSON as? NSMutableArray else {
apiError(error: "")
return
}
let listOfItem:NSMutableArray = NSMutableArray()
for (_, element) in adsArray.enumerate() {
let adsItem = Mapper<OrderList>().map(element)
listOfItem.addObject(adsItem!)
}
success(result:listOfItem)
case .Failure(let data):
print(data)
}
}
}
class OrderListViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {
@IBOutlet weak var table_OrderList: UITableView!
var listOFOrder:NSMutableArray =[]
override func viewDidLoad() {
slideMenuController()?.addLeftBarButtonWithImage(UIImage(named: "ic_menu_black_24dp")!)
slideMenuController()?.addRightBarButtonWithImage(UIImage(named: "ic_notifications_black_24dp")!)
WebServiceManager.getDataFromService("", success: { (result) in
listOFOrder = result as NSMutableArray
self.recordTable?.reloadData()
}) { (error) in
}
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell : OrderList_Cell = tableView.dequeueReusableCellWithIdentifier("OrderList_Cell") as! OrderList_Cell
return cell
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return listOFOrder.count
