仅在特定设备上应用程序崩溃

Question

在使用Skylink添加VoIP Pushwoosh(通过Pushwoosh)为VoIP应用程序后，我面临着崩溃，只在我的一个设备上(iPhone 5s8.4)。看上去是关于视频拍摄的。另一个测试人员感觉很好(iPhone 5s，iPhone 6，8.4.1，9.1)，当我强行将它连接到房间时，我的iPhone 4s并没有崩溃--无需VoIP推送。

UPD :在另一个设备上随机复制崩溃。

下面是破烂的日志：

这里的所有无崩溃日志看起来都是：

有什么想法吗？

UPD：cricket::VideoCapturer::SetCaptureState(cricket::CaptureState)上的碰撞点

Answer 1

问题是，标准推送似乎是在主队列中处理的，而VoIP推送则不是。所以在我的

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

我不得不补充

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

现在一切都好了。希望这能帮上忙。干杯!
