我正在使用 swift5 構建 ios 應用程式。所以在我看來，我創建了 TableView 來顯示一些資訊。當用戶打開視圖時，我呼叫 Web 服務來檢索要顯示在我的 TableView 中的資料。但我還希望用戶可以像在正常應用程式中一樣重繪 表的內容。
所以這是我的表視圖的代碼：
extension HomeVC : UITableViewDataSource {
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.arrListAll.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! homcell
/*var arrList:[Result] = []
if buttonTag == 0{
arrList = self.arrListPending
}else if buttonTag == 1{
arrList = self.arrListProcess
}else if buttonTag == 2{
arrList = self.arrListCompleted
}else if buttonTag == 3{
arrList = self.arrListRejected
}*/
let order = self.arrListAll[indexPath.row]
let arrayArticoli = order.itemData
var strOrder:String = ""
for i in 0..<arrayArticoli.count {
var prodotto = arrayArticoli[i]
strOrder = "\(prodotto.itemQuantity) x \(prodotto.itemName)\n"
//devo verificare che ingredient name abbia qualcosa
if(prodotto.itemName != nil &&
prodotto.ingredientName != "" ){
var aggiunte = prodotto.ingredientName
var arr = aggiunte.components(separatedBy: ", ")
if(arr.count>0){
var cont = 0
for y in 0..<arr.count - 1 {
strOrder = (arr[y]) ", "
if(cont == 2){
cont = 0
strOrder = "\n"
}
cont = cont 1
}
if(i < (arrayArticoli.count - 1)){
strOrder = "\n"
}
}
}
}
var timeBooking:String? = order.timeBooking
if ((timeBooking?.isEmpty) != nil){
cell.lblTitlePrenotazione.text = "è una prenotazione, controlla l'orario \ndi prenotazione in fondo."
cell.lblTitlePrenotazione.backgroundColor = UIColor.yellow
cell.lbl_OrarioPrenotazione.text = "Prepara per le ore " (timeBooking)!
cell.lbl_OrarioPrenotazione.backgroundColor = UIColor.yellow
}else{
cell.lblTitlePrenotazione.text = ""
cell.lbl_OrarioPrenotazione.text = ""
}
cell.lblTitleOrderDetail.text = "DETTAGLIO ORDINE:"
cell.lblId.text = "ID : \(order.id)"
cell.lbl_Name.text = order.userName
let formatter = DateFormatter()
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
let date = formatter.date(from: order.dateTime)
formatter.dateFormat = "dd/MM/yyyy HH:mm"
cell.lbl_Date.text = "DATA : \(formatter.string(from: date!))"
cell.lbl_Number.text = "Numero : \(order.mobile)"
cell.lbl_OrderDetail.text = strOrder
//cell.lbl_OrderDetail.sizeToFit();
//cell.lbl_OrderDetail.adjustsFontSizeToFitWidth = false
//cell.lbl_OrderDetail.lineBreakMode = .byTruncatingTail
cell.lbl_OrderDetail.lineBreakMode = NSLineBreakMode.byWordWrapping
cell.lbl_DeliveryCharge.text = "Consegna \(kCurrency):\(order.deliveryCoast)"
let ordine = Double(order.totalOrder ?? "0.0")! Double(order.deliveryCoast ?? "0.0")!
cell.lbl_Total.text = "Totale \(kCurrency):\(ordine)"
cell.lbl_Paynet.text = "Ordine\(kCurrency):\(order.totalOrder)"
if(order.paymentType == "Cash"){
cell.lbl_PaymentType.text = "Pagamento in contanti :"
}else if(order.paymentType == "Card"){
cell.lbl_PaymentType.text = "Pagamento con carta :"
}
cell.btn_messa.tag = indexPath.row
cell.btn_messa.addTarget(self, action: #selector(goSendMessage), for: .touchUpInside)
cell.btnccall.tag = indexPath.row
cell.btnccall.addTarget(self, action: #selector(goReject), for: .touchUpInside)

if(order.status == self.st_pending){
cell.btn_Wait.setTitle("Accetta ordine",for: .normal)
cell.btn_Wait.isEnabled = true

cell.btn_Wait.setTitle("Ordine rifiutato dal Runner",for: .normal)
cell.btn_Wait.isEnabled = false
}
cell.btn_Wait.backgroundColor = UIColor.systemOrange
}else if(buttonTag == 1){
if(order.status == self.st_driver_accept){
cell.btn_Wait.setTitle("Ordine accettato dal Runner",for: .normal)
cell.btn_Wait.isEnabled = true
}else if(order.status == self.st_process){
cell.btn_Wait.setTitle("in Attesa che il Moover accetti",for: .normal)
cell.btn_Wait.isEnabled = false

cell.btn_Wait.setTitle("in Consegna",for: .normal)
cell.btn_Wait.isEnabled = false
}
cell.btn_Wait.backgroundColor = UIColor.systemOrange
}else if(buttonTag == 2){
cell.btn_Wait.setTitle("Ordine Consegnato",for: .normal)
cell.btn_Wait.backgroundColor = UIColor.systemOrange
cell.btn_Wait.isEnabled = false

cell.btn_Wait.setTitle("Ordine Cancellato",for: .normal)
cell.btn_Wait.backgroundColor = UIColor.red
cell.btn_Wait.isEnabled = false
}
return cell
}
func goHistoryOrder(indexRow indexRow: Int){
let order = self.arrListAll[indexRow]
if(order.status == self.st_driver_accept){
let objVC = kStoryboardMain.instantiateViewController(withIdentifier: "HistoryDetailVC") as! HistoryDetailVC
objVC.order = order
self.navigationController?.pushViewController(objVC, animated: true)
}
}
@objc func goAcceptMove(butt:UIButton) {
let order = self.arrListAll[butt.tag]
if(order.status == self.st_pending){
cambiaStatoOrdine(strStatu: "Process", strId: order.id)
}else if(order.status == self.st_driver_accept){
goHistoryOrder(indexRow: butt.tag)
}
}
@objc func goSendMessage(butt:UIButton) {
let order = self.arrListAll[butt.tag]
let objVC = kStoryboardMain.instantiateViewController(withIdentifier: "UserChat") as! UserChat
objVC.receiverId = order.userID
objVC.userName = order.userName
self.navigationController?.pushViewController(objVC, animated: true)
}
@objc func goReject(butt:UIButton) {
}
}
現在當用戶打開視圖時，它可以顯示這個視圖：
現在如果用戶從下到上滾動表格，表格顯示使用其他順序，但是當用戶從上到下滾動表格并且表格到達第一個元素時，我想呼叫一個方法來獲取所有新元素資料并重繪 表格內容。
uj5u.com熱心網友回復：
您可以使用 UIRefreshControl（鏈接到檔案），使用它的簡單方法是：
func setupTableView() {
//You can add tableView.delegate = self and
// and tableView.dataSource = self here
// And here is the code to setup the refresh control
tableView.refreshControl = UIRefreshControl()
tableView.refreshControl?.addTarget(self, action:
#selector(handleRefreshControl),
for: .valueChanged)
}
func handleRefreshControl() {
//This method gets called when the user pulls to refresh on the table view so you can refresh the data source here and make sure to call .endRefreshing on the refresh control to stop the loading animation
}
現在在你的viewDidLoad方法中確保呼叫該setupTableView方法。
