我正在共享在tableview上选择的whats应用程序上的数据，因此我有两个选项来选择tableview行，一个是Select All，另一个是在didSelect上，所以当我全选时，share是完美的工作，我在这里共享编码数据是我用于共享所有表视图数据的数据
我的结构模型代码
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
}
}
这是我要获取数据的api表单
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()
}
})
}
所以我将所有数据存储在quotationSeelctedData中并进行如下编码
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")
}
我用高位代码对存储在quotationSeelctedData数组中的数据进行编码
现在，当在表视图中没有选择任何数据并且使用didSelect单击时，我仅选择一个数据并仅共享选择的数据，所以请帮助我如何仅将选择的数据共享到whats应用程序
我的意思是说，只是想共享选定的数据，所以请告诉我如何将数据存储在没有选择的数组中
我正在像下面的应用程序中共享数据

答案 0 :(得分：0)
let yourDataModel = [QuotationListDataModel]
从选定的tableViewCell中获取数据：
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)
}
