将tableview所选数据共享到Whats App

Question

i am sharing data on whats app which is selected on tableview so i have two option to select tableview rows One is Select All and another is on didSelect so when i select all then share is work perfect and i am sharing encoded data here is my data for sharing all tableview data

Code Of My struct model

class QuotationListDataModel: Encodable{
    var id: String?
    var quantity: String?
    var margin: String?
    var part_number: String?
    var total_price: String?
    var freight: String?

    init(id: String?,quantity: String?,margin: String?,part_number: String,total_price: String,freight: String) {
        self.id = id
        self.quantity = quantity
        self.margin = margin
        self.part_number = part_number
        self.total_price = total_price
        self.freight = freight
    }
}

here is my api form with i am getting data

var quotationSeelctedData = [QuotationListDataModel]()

func quotationListAPI(){
    let preferences = UserDefaults.standard
    let uid = "u_id"
    let acTkn = "acc_tkn"

    let u_ID = preferences.object(forKey: uid)
    let A_Token = preferences.object(forKey: acTkn)

    let params = ["user_id": u_ID!, "access_token": A_Token!]
    print(params)
    self.viewMainSpinner.isHidden = false
    self.viewInnerSpinner.startAnimating()
    Alamofire.request(quatationlist, method: .post, parameters: params).responseJSON(completionHandler: {(response) in
        switch response.result{
        case.success(let value):
            let json  = JSON(value)
            print(json)
            let data = json["quation_list"]
            print(data)
            if data == []{
                self.viewMainSpinner.isHidden = true
                self.viewInnerSpinner.stopAnimating()
            }else{
                data.array?.forEach({ (qList) in
                    let id = qList["id"].stringValue
                    let quantity = qList["quantity"].stringValue
                    let margin = qList["margin"].stringValue
                    let part_number = qList["part_number"].stringValue
                    let total_price = qList["total_price"].stringValue
                    let freight = qList["freight"].stringValue
                    self.quotationSeelctedData.append(QuotationListDataModel(id: String(describing: id), quantity: String(describing: quantity), margin: String(describing: margin), part_number: String(describing: part_number), total_price: String(describing: total_price), freight: String(describing: freight)))
                })
                self.tblListView.reloadData()
                self.viewMainSpinner.isHidden = true
                self.viewInnerSpinner.stopAnimating()
            }
        case.failure(let error):
            print(error.localizedDescription)
            self.viewMainSpinner.isHidden = true
            self.viewInnerSpinner.stopAnimating()
        }

    })
}

so i am storing all data in quotationSeelctedData and encode like below

    let encoder = JSONEncoder()
    encoder.outputFormatting = .prettyPrinted
    do {
        let jsonData = try encoder.encode(quotationSeelctedData)
        if let jsonString = String.init(data: jsonData, encoding: .utf8) {
            print(jsonString)
            let stringwithoutquotes = jsonString.replacingOccurrences(of: "{", with: "")
            let removebracket1 = stringwithoutquotes.replacingOccurrences(of: "}", with: "")
            let removebracket2 = removebracket1.replacingOccurrences(of: "[", with: "")
            let removebracket3 = removebracket2.replacingOccurrences(of: "]", with: "")
            self.jsString = removebracket3
        }
    } catch {
        print("the encoding failed")
    }

with upper code i am encode data in which store in quotationSeelctedData array

so now when there is no data selected in tableview and with didSelect click i am select only one data and share only selected data so please help me how to share only selected data to whats app

i mean to say is that is just want to share selected data so please tell me how to store data in array on did select

Answer 1

let yourDataModel = [QuotationListDataModel]

get data from the selected tableViewCell :

    func tableView(_ tableView: UITableView, 
         didSelectRowAt indexPath: IndexPath){

    let dataToBeSent = yourDataModel[indexPath.row] 

    // share this data in whatsApp using UIActivityViewController:

    let items = [dataToBeSent]
    let activityViewController = UIActivityViewController(activityItems: items, applicationActivities: nil)

    present(activityViewController, animated: true)

  }
