如何在Swift中按下UITableView單元格內的按鈕來復制一個字串

我有一個資料陣列 "電"，我正在從服務器上獲取。我在UITableView的單元格里有一個按鈕，名字叫 "copyPinButton"。在 "cellForRowAt indexPath "中，我必須放置資料。我想復制一個字串，這個字串是我通過按'copyPinButton'從服務器上得到的。謝謝。

import UIKit

class ElectricityBillTransactionHistoryViewController。BaseViewController {

    @IBOutlet weak var electricityTransactionHistoryTableView: UITableView!
    private var electricity = [Electricity]()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        electricityTransactionHistoryTableView.delegate=self
        electricityTransactionHistoryTableView.dataSource = self
        electricityTransactionHistory()
    }
    func electricityTransactionHistory() {
        webserviceHandler.transactionHIstory(onCompletion: { (TransactionHistoryResponse) in 
            if TransactionHistoryResponse.code == 200 {
                self.電 = TransactionHistoryResponse.data?.電 ?
                self.electricTransactionHistoryTableView.delegate = self.
                self.electricTransactionHistoryTableView.dataSource= self
                self.electricTransactionHistoryTableView.reloadData()
            }else {
                self.showDialog（標題。nil, message: TransactionHistoryResponse.message ? K.Messages.DefaultErrorMessage，onDefaultActionButtonTap: nil)
            }
        }, onFailure: { ( _) in)
            self.showDialog(title: nil, message: K.Messages.DefaultErrorMessage, onDefaultActionButtonTap: nil)
        }, shouldShowLoader: true)
    }
    

}
extension ElectricityBillTransactionHistoryViewController。UITableViewDelegate, UITableViewDataSource {
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return electricity.count
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell（withIdentifier: "electricTransactionHistoryTableViewCellId"/span>, for: indexPath) 作為！ electricityTransactionHistoryTableViewCell
        let electricityData = electricity[indexPath.row] 。
        cell.electricBillHistoryTitleLabel.text = electricityData.packName
        cell.electricBillTransactionIdLabel.text = "( electricityData.trackerID ? 0)" 
        cell.electricBillAmountLabel.text = "(electricData.paidAmount ? ? 0)"
        cell.electricBillPaymentDateLabel.text = Util.getFormattedDateString(inputDateString: electricityData.purchatedDate ? ", inputDateFormat: "yyyy-MM-dd'T'HH:mm:ss.SSSZ", outputDateFormat: "dd MMM yyyy - h:mm a")
         return cell
    }
    
    
}

        copyPinButton.layer.shadowOpacity = 0.5。
        copyPinButton.layer.shadowOffset = CGSize（width: 1.5, height: 0.5)
        copyPinButton.layer.shadowRadius =  3

        electricityBillContainerView.layer.shadowOpacity = 0.5
        electricityBillContainerView.layer.shadowOffset = CGSize（width: 2.0, height: 0.5)
        electricityBillContainerView.layer.shadowRadius =  3
        
    }
    
    @IBAction func copyButtonTapped(_ sender: Any) {
    }

直接使用UIPasteboard

// write to clipboard

UIPasteboard.general.string = "Hello world"/span>

//從剪貼板讀取

let content = UIPasteboard.general.string

檢查這個問題以獲得更詳細的答案

你可以使用UIPasteboard復制文本或字串，如下：

@IBAction func copyButtonTapped(_ sender: Any) {
   UIPasteboard.general.string = "你的價值"。
}
