如何直接从 CarPlay 拨打电话而不需要智能手机确认？

Question

我正在为 CarPlay 开发一个应用程序，我希望用户在点击“拨打电话”按钮时能够直接从 CarPlay 拨打电话。然而，现在，它会在连接的智能手机上打开确认信息。如何直接从 CarPlay 进行通话？

private func makePhoneCall(phoneNumber: String) {
        guard let url = URL(string: "tel://\(phoneNumber)"), UIApplication.shared.canOpenURL(url) else {
               print("Error to make call.")
               return
           }
           
           UIApplication.shared.open(url, options: [:], completionHandler: nil)
    }


 func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didConnect interfaceController: CPInterfaceController) {
        self.interfaceController = interfaceController
        
       
        showCallConfirmation(phoneNumber: "199999999999")
        
    }

  private func showCallConfirmation(phoneNumber: String) {
        guard let interfaceController = self.interfaceController else {
            print("Interface Controller is not available")
            return
        }

        let confirmAction = CPAlertAction(title: "Call Me", style: .default) { [weak self] _ in
            self?.makePhoneCall(phoneNumber: phoneNumber)
        }
        
        let cancelAction = CPAlertAction(title: "Cancel", style: .cancel) { _ in
        }

        let alertTemplate = CPAlertTemplate(titleVariants: ["Do you want make phone call? \(phoneNumber)?"],
                                            actions: [confirmAction, cancelAction])

        interfaceController.presentTemplate(alertTemplate, animated: true)
    }

Answer 1

您的想法是正确的，打开了

tel

网址，但您在手机上收到提示，因为您正在使用

UIApplication.shared.open

。

您需要在 open

 上调用等效的 

UIScene 函数，该函数在 CarPlay 应用程序启动时传递给您的

CPTemplateApplicationSceneDelegate

。
