I'm facing the same problem. Could you please tell me how you solved it? oc PKPushRegistry *pushRegistry = [[PKPushRegistry alloc] initWithQueue:dispatch_get_main_queue()]; pushRegistry.delegate = self; pushRegistry.desiredPushTypes = [NSSet setWithObject:PKPushTypeVoIP]; (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(PKPushType)type withCompletionHandler:(void(^)(void))completion{ NSLog(@"Received void push notification data"); if (type == PKPushTypeVoIP) { NSDictionary *callKit = [payload.dictionaryPayload objectForKey:@"callkit"]; NSString *handle = [callKit objectForKey:@"handle"]; NSString *uuidString = [callKit objectForKey:@"uuid"]; self.callInfo = payload.dictionaryPayload; // 发起对话 if (@available(iOS 17.4, *)) { [[LiveCommunicationWrapper shared] startConversationWithTargetHandleValue:handle uuid:uuidString completion:^(BOOL status, NSError * _Nullable error) { completion(); }]; } else { completion(); } } else { NSLog(@"Received push notification of type: %@", type); completion(); } } swift @available(iOS 17.4, *) @objc class LiveCommunicationWrapper: NSObject, ConversationManagerDelegate { @objc static let shared = LiveCommunicationWrapper() let conversationManager = ConversationManager(configuration: ConversationManager.Configuration(ringtoneName: "default_ringtone", iconTemplateImageData: nil, maximumConversationGroups: 1, maximumConversationsPerConversationGroup: 1, includesConversationInRecents: false, supportsVideo: false, supportedHandleTypes: [.generic])) private override init() { super.init() conversationManager.delegate = self print("conversationManager init.") } @objc func startConversation(targetHandleValue : String,uuid : String, completion: @escaping (Bool, Error?) -> Void ){ guard let conversationUUID = UUID(uuidString: uuid) else { let error = NSError(domain: "InvalidUUID", code: 1, userInfo: [NSLocalizedDescriptionKey: "Invalid UUID string"]) completion(false, error) return } let hasVideo = false; var update = Conversation.Update(members: [Handle(type: .generic, value: uuid, displayName: uuid)]) if hasVideo { update.capabilities = [.video, .playingTones] } else { update.capabilities = .playingTones } let incomingCallerHandle = Handle(type: .generic, value: targetHandleValue ,displayName: targetHandleValue) Task { do { try await conversationManager.reportNewIncomingConversation(uuid: conversationUUID, update: update) completion(true, nil) } catch { print("An error occurred: \(error.localizedDescription)") completion(false, error) } } }
