我在iPod touch上运行myapp，我发现它错过了一些库。那是什么原因吗？

答案 0 :(得分：5)
信号0通常（但不总是）与耗尽内存的设备相关。在我自己的测试中，我看到一个应用程序在加载大图像或内存管理不良后退出信号0。
重新启动设备可能会有所帮助，但由于您似乎正在使用越狱的iPhone / iPod，因此可能存在任何问题。
我猜想所有的后台应用程序占用了大量的内存，而你的应用程序却没有留下任何内容。在调试器中挂钩时效果会被放大，因为这也需要额外的内存来运行。
我的建议是不要使用越狱的iPhone / iPod。但那完全是你的呼唤。

这些消息来自使用jail破坏的手机。它们很可能与您的错误无关。如果没有更多信息，我们将无法帮助您追踪错误。
答案 2 :(得分：0)
看来你正在使用一些库。请以正确的方式包含它们。“
如果不是原因，请提供更多信息。
