虽然是未接来电，但会调用 didReceiveIncomingCall [英] didReceiveIncomingCall is called although it is a missed call

问题描述

当应用在后台并且有来电但用户没有接听时.当用户重新进入应用时 - (void)client:(id)client didReceiveIncomingCall:(id)call 正在被调用.

When the app is in background and an incoming call has happened and the user didn't pick up. When the user gets back into the app - (void)client:(id<SINCallClient>)client didReceiveIncomingCall:(id<SINCall>)call is being invoked.

重现步骤

• 用户 A 呼叫者
• 用户 B 接收者
• 用户 B 在后台运行该应用
• 用户 B 呼叫用户 A
• 用户 B 在用户 A 接听前挂断电话
• 用户 B 打开应用程序，- (void)client:(id)client didReceiveIncomingCall:(id)call 立即被调用，call.status 是 0 所以 SINCCallStateInitiating

• User A caller
• User B receiver
• User B has the app in background
• User B calls user A
• User B hangs up the call before user A picks up
• User B opens the app and - (void)client:(id<SINCallClient>)client didReceiveIncomingCall:(id<SINCall>)call gets immediately called and the call.status is 0 so SINCallStateInitiating

这是正常行为吗?有没有办法知道这个电话不再可用"?

Is this the normal behaviour? Is there a way to know this call is not "available" anymore?

我正在使用 iOS 10 和 Sinch 版本:3.9.7-26289c8

编辑

显示我如何初始化 Sinch 客户端、托管推送、通知等的代码.以下所有代码都发生在 AppDelegate 中

Showing the code on how I initialize Sinch client, Manged Push, Notifications, etc. All the below code takes place inside the AppDelegate

AppDelegate

@interface AppDelegate()

初始化 SINManagedPush:

didFinishLaunchingWithOptions

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

初始化 Sinch 客户端:一旦用户登录

- (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 -> 无论调用是否不再存在"，都会调用此方法

SINCallClientDelegate -> This is called no matter if the call doesn't "exist" anymore

- (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}];
}

推荐答案

您是否自己将推送数据中继到客户端?如果是这样，您可以检查结果中的有效负载

Are you relaying the push data to the client your self? If so you can check the payload in the result

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

示例使用:

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 
}
