Question

这里我分为几个部分，每个部分都有行，具体取决于计数所以对于每一行，单选按钮都在那里，我需要为所有部分激活一个单选按钮，但我无法实现它和部分的图像将显示here，我的代码是

@IBAction func paymentRadioAction(_ sender: KGRadioButton) {
        let chekIndex = self.checkIsPaymentRadioSelect.index(of: sender.tag)
        if sender.isSelected {

        } else{
            if(chekIndex == nil){
                self.checkIsPaymentRadioSelect.removeAll(keepingCapacity: false)
                self.checkIsPaymentRadioSelect.append(sender.tag)
                self.shippingTableView.reloadData()
            }
        }
    }

这是indexpath

中行的单元格的代码

 let cell = tableView.dequeueReusableCell(withIdentifier: "shippingCell", for: indexPath) as! shippingMethodTableViewCell
            var key = self.keys[indexPath.section]
            print(key)
            var a :[Any]  = arrayss[key] as! [Any]
            var dictionary = a[indexPath.row] as! [String:Any]
            let name = dictionary["name"]
            let price = dictionary ["price"]
            cell.methodNameLabel.text = name  as! String
            cell.priceLabel.text = price as! String
            let checkIndex = self.checkIsPaymentRadioSelect.index(of: indexPath.row)
            if(checkIndex != nil){
                cell.radioButton.isSelected = true
            }else{
                cell.radioButton.isSelected = false
            }
            return cell
        }

在这里，您不必使用数组来跟踪所选的单选按钮

将chekIndex作为IndexPath类型的全局变量var chekIndex:IndexPath? 并修改如下代码

   @IBAction func paymentRadioAction(_ sender: KGRadioButton) {
     let center = sender.center;
    let centralPOint = sender.superview?.convert(sender.center, to:self.shippingTableView )
    let indexPath =  self.shippingTableView.indexPathForRow(at: centralPoint)

    if sender.isSelected {

    } else{
        chekIndex = indexPath
        self.shippingTableView.reloadData()
    }
}


let cell = tableView.dequeueReusableCell(withIdentifier: "shippingCell", for: indexPath) as! shippingMethodTableViewCell
var key = self.keys[indexPath.section]
print(key)
var a :[Any]  = arrayss[key] as! [Any]
var dictionary = a[indexPath.row] as! [String:Any]
let name = dictionary["name"]
let price = dictionary ["price"]
cell.methodNameLabel.text = name  as! String
cell.priceLabel.text = price as! String
if checkIndex == indexPath {
    cell.radioButton.isSelected = true
} else {
    cell.radioButton.isSelected = false

}
return cell
}

如何激活所有部分只有一个单选按钮？
