 func paymentMethodURL() {
    let url = NSURL(string: self.paymentmethodURL)
    URLSession.shared.dataTask(with: (url as URL?)!, completionHandler: {(data, response, error) -> Void in
        if let jsonObj = try? JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? NSDictionary {
             self.paymentmethodsArray = (jsonObj!.value(forKey: "payment method") as? [[String: AnyObject]])!
            OperationQueue.main.addOperation({
                self.tableDetails.reloadData()
            })
        }
    }).resume()
}
func paymentreviewURL() {
    let url = NSURL(string: self.paymentReviewURL)
    URLSession.shared.dataTask(with: (url as URL?)!, completionHandler: {(data, response, error) -> Void in
        if let jsonObj = try? JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? NSDictionary {
            let arrayss = jsonObj?.allKeys
                OperationQueue.main.addOperation({

            })
        }

@IBAction func selectRadioButton(_ sender: KGRadioButton) {
    sender.isSelected = !sender.isSelected

    if sender.isSelected {

    } else{

    }
}
func numberOfSections(in tableView: UITableView) -> Int{
    return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return paymentmethodsArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let paymentcell = tableView.dequeueReusableCell(withIdentifier: "cell",for:indexPath) as! paymentTableViewCell
    tableDetails.isHidden = false
    myActivityIndicator.stopAnimating()
    let arr = self.paymentmethodsArray[indexPath.row]
    paymentcell.paymentNameLabel.text = arr["name"]as? String

你应该喜欢这样:

 var tagSelected = -1

//假设每个单选按钮都有标签 0 1 2

@IBAction func selectRadioButton(_ sender: KGRadioButton) {
    tagSelected = sender.tag 
    tableView.reloadData()
}

//RowAtIndexPath 的单元格

 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

   guard let cell = tableView.dequeueReusableCell(withIdentifier: 
   kCellReuseIdentifier, for: indexPath) as? YourCell else {
   fatalError("Cell is not dequeued")
   }

   //logic for match indexPath.row /section to your button tags
   if indexPath.row == tagSelected {
   //selected here your radio button
   } else {
   //unselect all others
   }
    //other code

  return cell
 }
