ios - iOS 11中的VOIP Sinch在后台无法运行

我使用Sinch VOIP在iOS 11.1.2中的App-To-App之间进行 call
当应用程序状态为前台但在后台运行并且终止时，效果很好，打开应用程序控制台打印后没有任何反应

    subscribeSequence = 1;
    timetoken = 0;
    useVoIPNetworkServiceType = 0;
}

我将VOIP和APNS证书上传到Sinch仪表板，并使用SINManagedPush和PushKit我的代码是

在didFinishLaunchingWithOptions中设置推送管理器和SINClient

    self.push = [Sinch managedPushWithAPSEnvironment:SINAPSEnvironmentAutomatic];
    self.push.delegate = self;
    [self.push setDesiredPushTypeAutomatically];
    void (^onUserDidLogin)(NSString *) = ^(NSString *userId) {
    [self.push registerUserNotificationSettings];
    [self initSinchClientWithUserId:userId];
    };
    [[NSNotificationCenter defaultCenter]
    addObserverForName:@"UserDidLoginNotification"
    object:nil
    queue:nil
    usingBlock:^(NSNotification *note) {
     NSString *userId = note.userInfo[@"userId"];

     [[NSUserDefaults standardUserDefaults] setObject:userId     forKey:@"userId"];
     [[NSUserDefaults standardUserDefaults] synchronize];
     onUserDidLogin(userId);
     }];


     - (void)initSinchClientWithUserId:(NSString *)userId {
    if (!_client) {
    _client = [Sinch clientWithApplicationKey:@"APP-Key"
                            applicationSecret:@"APP-Secret"
                              environmentHost:@"sandbox.sinch.com"
                                       userId:userId];

    _client.delegate = self;
    _client.callClient.delegate = self;
    [_client setSupportCalling:YES];
    [_client enableManagedPushNotifications];

    [_client start];
    [_client startListeningOnActiveConnection];
    _callKitProvider = [[SINCallKitProvider alloc] initWithClient:_client];


    }
    }

获取设备 token

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{


[self.push application:application didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
}

-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
NSLog(@"User Info : %@",notification.request.content.userInfo);
completionHandler(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge);

[self.push application:[UIApplication sharedApplication] didReceiveRemoteNotification:notification.request.content.userInfo];
}


-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler{
NSLog(@"User Info : %@",response.notification.request.content.userInfo);
completionHandler();
[self.push application:[UIApplication sharedApplication] didReceiveRemoteNotification:response.notification.request.content.userInfo];
}


- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
[self.push application:application didReceiveRemoteNotification:userInfo];
}

PushKit

-(void)voipRegistration
{
PKPushRegistry* voipRegistry = [[PKPushRegistry alloc] initWithQueue:dispatch_get_main_queue()];
voipRegistry.delegate = self;
voipRegistry.desiredPushTypes = [NSSet setWithObject:PKPushTypeVoIP];
}

 -(void)pushRegistry:(PKPushRegistry *)registry didUpdatePushCredentials:(PKPushCredentials *)credentials forType:(NSString *)type
{

[_client registerPushNotificationData:credentials.token];
 }
 -(void)pushRegistry:(PKPushRegistry *)registry   didInvalidatePushTokenForType:(PKPushType)type{


NSLog(@"invalidated");

 }

4.当SINClient启动时调用voipRegistration

- (void)clientDidStart:(id<SINClient>)client {
NSLog(@"Sinch client started successfully (version: %@)", [Sinch version]);
[self voipRegistration];
}

5，实现SINManagedPushDelegate和SINCallClientDelegate

- (void)client:(id<SINCallClient>)client didReceiveIncomingCall:(id<SINCall>)call {

UIViewController *top = self.window.rootViewController;
while (top.presentedViewController) {
    top = top.presentedViewController;
}
[top performSegueWithIdentifier:@"callView" sender:call];
}

- (SINLocalNotification *)client:(id<SINClient>)client localNotificationForIncomingCall:(id<SINCall>)call {
SINLocalNotification *notification = [[SINLocalNotification alloc] init];
NSArray * ansAr = @[@"رد",@"Answer"];
NSArray * MsgAr = @[[NSString stringWithFormat:@"مكالمة لم يرد عليها من %@", [call remoteUserId]],[NSString stringWithFormat:@"Incoming call from %@", [call remoteUserId]]];
notification.alertAction = ansAr[self.languageID];
notification.alertBody = MsgAr[self.languageID];
return notification;
}
- (void)client:(id<SINClient>)client willReceiveIncomingCall:(id<SINCall>)call {

[self.callKitProvider reportNewIncomingCall:call];
}

这些是代码，如果我忘记了任何内容，请帮助我。
我检查了credentials.token不为null。
感谢您的帮助。

最佳答案

使用以下代码设置Sinch管理的推送时:

self.push = [Sinch managedPushWithAPSEnvironment:SINAPSEnvironmentAutomatic];
self.push.delegate = self;
[self.push setDesiredPushTypeAutomatically];

Sinch SDK将自动为您注册所有PushKit。因此，描述中的第3步和第4步不是必需的，也不应该在那里。也不需要步骤2中的部分代码。请从SDK下载包中查看Sinch CallKit示例应用程序，并参考该应用程序的实现。

以下是使用3.12.4 Sinch SDK CallKit示例应用程序制作的演示视频，没有进行任何调整，该演示中使用的设备是运行iOS 11的iPhone7，它将在后台，中止和锁屏模式下接收来电:

另外，请注意callKit仅适用于VoIP推送，您是否已将正确类型的推送证书上载到Sinch Portal？
