我正在尝试将图像获取和处理卸载到AIR / iOS应用中的Worker。但是，在调用loader.load（）之后，加载器只会获得OPEN事件。此外，它会杀死任何Timers或Event.ENTER_FRAME监听，尽管Worker的状态显示为“正在运行”。
我的代码在Android设备（Galaxy S5）上的AIR模拟器和中按预期运行，但在iOS模拟器和设备本身都死了。以下是我的测试应用程序的每个AIR Sim，iOS Sim和iPhone的跟踪输出。您会注意到，对于iOS测试，它永远不会“完成”。我正在尝试同时加载4张图片，但也只是1：

我的代码如下。为了清晰起见，我删除了PROGESS和HTTP_STATUS事件，因为无论如何iOS测试都没有达到目标。
