Voip Pushes のテスト中に、このエラーに遭遇しました

これは、アプリがクラッシュしたときに XCode が指し示すコードです。

- (void)processRemoteNotification:(NSDictionary *)userInfo {

    NSDictionary *aps = [userInfo objectForKey:@"aps"];

    if (aps != nil) {
        NSDictionary *alert = [aps objectForKey:@"alert"];
        if (alert != nil) {
            NSString *loc_key = [alert objectForKey:@"loc-key"];
            /* if we receive a remote notification, it is probably because our TCP background socket was no more working.
             As a result, break it and refresh registers in order to make sure to receive incoming INVITE or MESSAGE*/
            if (linphone_core_get_calls(LC) == NULL) { // if there are calls, obviously our TCP socket shall be working
                //linphone_core_set_network_reachable(LC, FALSE);
                if (!linphone_core_is_network_reachable(LC)) {
                    LinphoneManager.instance.connectivity = none; //Force connectivity to be discovered again
                    [LinphoneManager.instance setupNetworkReachabilityCallback];
                }
                if (loc_key != nil) {

                    NSString *callId = [userInfo objectForKey:@"call-id"];
                    if (callId != nil) {
                        [LinphoneManager.instance addPushCallId:callId];
                    } else {
                        LOGE(@"PushNotification: does not have call-id yet, fix it !");
                    }

                    if ([loc_key isEqualToString:@"IC_MSG"]) {
                        [self fixRing];
                    }
                }
            }
        }
    }
    LOGI(@"Notification %@ processed", userInfo.description);
}

ご覧のとおり、プッシュ通知は受け取りますが、ログのみで、電話に表示されず、アプリがクラッシュします。

「アラート」ディクショナリのキー「loc-key」の値にアクセスしていますが、ペイロード「アラート」ディクショナリにはこのキーの値がないため、でクラッシュしていますNSString *loc_key = [alert objectForKey:@"loc-key"];

私は同じ問題に遭遇しました。サーバー側は、「Incoming Notification」文字列のみを含む通知をプッシュしていました。したがって、objectForKey:@"loc-key" はクラッシュします - プッシュ通知に予期された形式の文字列が含まれていませんでした。これを回避するために、サーバーからのプッシュ通知の内容を確認しました。従来のプッシュ サーバーの場合、アラートと「着信通知」を比較すると true になります。この場合、アラートを nil に設定してクラッシュを回避します。

NSDictionary *alert = [aps objectForKey:@"alert"];
BOOL result = [alert isEqual:@"Incoming Notification"];
if (result == true)
{
   if (linphone_core_get_calls(LC) == NULL) { // if there are calls,    obviously our TCP socket shall be working
      if (!linphone_core_is_network_reachable(LC)) {
         LinphoneManager.instance.connectivity = none; //Force connectivity to be discovered again
        [LinphoneManager.instance setupNetworkReachabilityCallback];
      }
   }
   alert = nil;
}
if (alert != nil) {
   ...
}
