Swift Question

How can i access value of other Mappble class object.(Alamofire Object Mapper)

in my app i am first time using AlamofireObjectMapper.
So i am mapping api response data in one class and then i want to use that data.
So here is my code that how i map object

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)
}

}
}


and here is the class where i saving my data

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"]

}

}


now in my OrderListViewController i want to use this data so how can i use this??

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

}
}


for example i want to print message value in my tableview cell label. so how can i get that value form OrderList?

Thanks slava its give me some solution. but my json response give me array. So how can i manage it? and i want to return in numberofrowinSetcion is count of array so how can i do this. please see my updated question.

here is my api response.

"Message": "records are available",
"Result": [
{
"id": 30162,
"status_id": 2,

]
}

Answer

You need a local variable in your controller to store all the received information that will be used to fill the table. Something like that should do:

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
        }
    }
}

Note: the code should be correct in case you receive the single object in JSON from backend. If backend sends the array of objects - you'll need to use array to store local data (private var listOfOrderLists: [OrderList]) and use Alamofire.request(...).responseArray(...) instead. But the idea about local variable is still the same.
