Приложение вылетает только на конкретном устройстве

Question

После добавления VoIP-нажатий (через Pushwoosh) для VoIP-приложения с использованием Skylink SDK я столкнулся с катастрофой, только на одном из моих устройств (iPhone 5s 8.4). Похоже, речь идет о захвате видео. Другие тестировщики чувствуют себя хорошо (iPhone 5s, iPhone 6, 8.4.1, 9.1), и мой iPhone 4 не сбой, когда я принудительно подключаю его к комнате без VoIP-нажатий.

UPD: сбой случайным образом воспроизводится на других устройствах

Вот врезаться журналы:

Любые идеи?

UPD: Crashlytics точки на cricket::VideoCapturer::SetCaptureState(cricket::CaptureState)

Answer 1

Дело в том, что стандартные толчки, кажется, обрабатываются в основной очереди, в то время как VoIP толчки не являются. Так что в моем

- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(NSString *)type 

мне пришлось добавить

dispatch_async(dispatch_get_main_queue(), ^{ 
     [[P2PConnectionManager sharedManager] handlePushNotification:userInfo]; 
    }); 

И теперь все, кажется, хорошо. Надеюсь, это поможет кому-то. Ура!
