如何使用 CallKit 拒绝观察到的通话？

Question

我对 Swift 编程完全陌生，我不知道如何进行这项工作。 基本上，我有一个 iOS 应用程序，它可以观察来电，如果来电者号码等于用户定义的要拒绝的号码，则自动拒绝它，而不向用户显示任何通知（该应用程序仅供我私人使用）。

目前我有这段代码可以观察来电。它的工作原理就像一个魅力，但我不知道如何让它拒绝来电（目前是所有电话号码）。

import CallKit

class CallTest: NSObject, CXCallObserverDelegate, ObservableObject {
    @Published var incomingCallNumber: String?
    
    let callObserver = CXCallObserver()

    override init() {
        super.init()

        callObserver.setDelegate(self, queue: nil)
    }
    
    func callObserver(_ callObserver: CXCallObserver, callChanged call: CXCall) {
        if (call.isOutgoing == false && call.hasConnected == false) {
            print("Incoming call")
        }
    }
}

我尝试过这样拒绝来电。

import CallKit

class CallTest: NSObject, CXCallObserverDelegate, ObservableObject {
    @Published var incomingCallNumber: String?
    
    let callObserver = CXCallObserver()

    override init() {
        super.init()

        callObserver.setDelegate(self, queue: nil)
    }
    
    func callObserver(_ callObserver: CXCallObserver, callChanged call: CXCall) {
        if (call.isOutgoing == false && call.hasConnected == false) {
            print("Incoming call")
let callController = CXCallController()
            let endCallAction = CXEndCallAction(call: call.uuid)
            let transaction = CXTransaction(action: endCallAction)

            callController.request(transaction) { error in
                if let error = error {
                    print("Error declining call: \(error)")
                } else {
                    print("Call declined successfully")
                }
            }
        }
    }
}

但我不断收到错误：

错误域=com.apple.CallKit.error.requesttransaction代码=2“（空）”

这意味着“unknownCallProvider”，但我不知道如何为此设置提供程序。

最终类CallKitSerivce：NSObject，CXProviderDelegate{

var provider: CXProvider?
let callController = CXCallController()

override init() {
    super.init()
    let providerConfiguration = CXProviderConfiguration(localizedName: "Calling App")
    providerConfiguration.supportsVideo = true
    providerConfiguration.maximumCallsPerCallGroup = 1
    providerConfiguration.supportedHandleTypes = [.generic]
    self.provider = CXProvider(configuration: providerConfiguration)
    self.provider?.setDelegate(self, queue: nil)
}

func reportIncomingCall(uuid: UUID, handle: String, hasVideo: Bool = false){
    let update = CXCallUpdate()
    update.remoteHandle = CXHandle(type: .generic, value: handle)
    update.hasVideo = hasVideo
    
    provider?.reportNewIncomingCall(with: uuid, update: update) { error in
        if let error = error{
            print(error)
        }else{
            print("incoming call reported successfully")
        }
    }
}

func startCall(uuid: UUID, handle: String, hasVideo: Bool = false){
    let handle = CXHandle(type: .generic, value: handle)
    let transaction = CXTransaction(action: CXStartCallAction(call: uuid, handle: handle))
    callController.request(transaction) { error in
        if let error = error {
            print(error)
        }else{
            print("call started successfully")
        }
    }
}

}

与您的观察者一起包括提供商，那么我希望错误会消失
