从 UIButton 调用

Question

在我的项目中，我试图在 UI 按钮处于顶部时进行 phone 调用。下面是实现，但是当我运行从模拟器或在我的 iPhone 上它不起作用时。我该如何解决？

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! ListOfCarsTableViewCell
        let carsIndex = carsArray[indexPath.row]           
      cell.phoneButton.setTitle(carsIndex.dealer.phone.toPhoneNumber(), for: .normal)
        
        return cell
        
    }
    
    @objc func callTapped(_ sender: UIButton) {
        let buttonPosition = sender.convert(CGPoint.zero, to: self.tableView)
        if let indexPath = tableView.indexPathForRow(at: buttonPosition){
            let phoneNumber = carsArray[indexPath.row].dealer.phone
            callNumber(phoneNumber: phoneNumber)
        }
        
    }
    
        func callNumber(phoneNumber:String) {
            if let phoneCallURL = URL(string: "\(phoneNumber)") {
                let application:UIApplication = UIApplication.shared
                if (application.canOpenURL(phoneCallURL)) {
                    application.open(phoneCallURL, options: [:], completionHandler: nil)
                }
            }
        }

Answer 1

在您的 url 字符串中添加“tel://”

func callNumber(phoneNumber:String) {
        if let url = URL(string: "tel://\(phoneNumber)") {
            UIApplication.shared.open(url, options: [:]) { success in
                if success {
                    print("Making phone call")
                } else {
                    print("Something went wrong while making phone call")
                }
            }
        } else {
            print("Failed to make phone call")
        }
    }

编辑：我发现 callTapped 操作与您的电话按钮没有关联。请在 cellForRowAt 函数中添加以下行。它将完美运行。

cell.phoneButton.addTarget(self, action: #selector(callTapped(_:)), for: .touchUpInside)

Answer 2

你可以试试

    cell.phoneButton.tag = indexPath.row
    cell.phoneButton.setTitle(carsIndex.dealer.phone.toPhoneNumber(), for: .normal)
    cell.phoneButton.addTarget(self, action: #selector(callTapped), for: .touchUpInside)

@objc func callTapped(_ sender: UIButton) {
    let phoneNumber = carsArray[sender.tag].dealer.phone
    callNumber(phoneNumber: phoneNumber)
    
}

另外别忘了在phone数字

前加上tel://
