didReceiveIncomingCall被调用，虽然它是一个未接来电

当应用程序在后台，并且来电已经发生，用户没有拿起。 当用户回到应用程序- (void)client:(id<SINCallClient>)client didReceiveIncomingCall:(id<SINCall>)call正在被调用。

重现步骤

• 用户来电者
• 用户B接收器
• 用户B在后台有应用程序
• 用户B呼叫用户A.
• 用户B在用户A接通之前挂断电话
• 用户B打开应用程序和- (void)client:(id<SINCallClient>)client didReceiveIncomingCall:(id<SINCall>)call立即被调用，并且call.status为0，所以SINCallStateInitiating

这是正常的行为？ 有没有办法知道这个电话是不是“可用”了？

我正在使用iOS 10和Sinch版本：3.9.7-26289c8

谢谢！

显示如何初始化Sinch客户端，Manged Push，Notifications等代码下面的所有代码都发生在AppDelegate

AppDelegate中

@interface AppDelegate ()<SINCallClientDelegate,SINManagedPushDelegate,SINClientDelegate>

初始化SINManagedPush ：

在didFinishLaunchingWithOptions中的didFinishLaunchingWithOptions

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

初始化Sinch客户端 ：用户login后

 - (void)initSinchClientWithUserId:(NSString *)userId { if (!_client) { _client = [Sinch clientWithApplicationKey:[BCEnvironment sinchAppKey] applicationSecret:[BCEnvironment sinchAppSecret] environmentHost:[BCEnvironment sinchEnvHost] userId:userId]; BCUser *user = [BCDataProvider loggedInUser]; [self.push setDisplayName:[user displayName]]; _client.delegate = self; _client.callClient.delegate = self; [_client setSupportCalling:YES]; [_client enableManagedPushNotifications]; [_client start]; } } 

注册远程通知

 - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { [self.push application:application didRegisterForRemoteNotificationsWithDeviceToken:deviceToken]; } 

接收推送通知

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

SINManagedPushDelegate

 - (void)managedPush:(id<SINManagedPush>)unused didReceiveIncomingPushWithPayload:(NSDictionary *)payload forType:(NSString *)pushType { [self.client relayRemotePushNotification:payload]; } 

SINCallClientDelegate – >不pipe呼叫是否“存在”，都会调用此函数

 - (void)client:(id<SINCallClient>)client didReceiveIncomingCall:(id<SINCall>)call { //This opens the calling screen, even if the call is "old" and the caller has already hangup or the call timed out, etc. Here is where I am having the issue [[NSNotificationCenter defaultCenter] postNotificationName:@"DidReceiveCall" object:nil userInfo:@{@"call":call}]; }

你是否将推送数据传递给客户？ 如果是这样，你可以检查结果中的有效载荷

https://download.sinch.com/docs/iOS/latest/reference/html/Protocols/SINNotificationResult.html#//api/name/isValid

使用示例：

 id result = [self.client relayLocalNotification:notification]; if ([result isCall] && [[result callResult] isTimedOut]) { NSString remoteUserId = [[result callResult] remoteUserId]; // present UIAlert indicating user has a missed call. } else if([result isMessage]){ NSString messageId = [[result messageResult] messageId]; // show view controller that highlights the particular message }
