iOS低内存崩溃问题，但使用非常低的内存 - 使用仪器检查

我有一个示例应用程序在模拟器上正常工作，但在设备上崩溃。我从Organizer的控制台上获得以下输出。它在很短的时间内崩溃。iOS低内存崩溃问题，但使用非常低的内存 - 使用仪器检查

使用仪器，内存泄漏，我看到内存使用量约为2-3 mb。使用内存分配，我发现大约8-9mb用于内存分配，而虚拟机跟踪器中没有任何内容。

控制台输出如下。任何人都可以建议做什么？

好的，所以试着在模拟器上进行分析。似乎它需要，在某些时候，70-80mb之前回到2-3 mb ....也许这就是问题... – Ahsan 2012-04-26 19:27:17

也没有肮脏或驻留使用虚拟机跟踪。 – Ahsan 2012-04-26 19:45:38

好了，好像一切都很好，我只是需要从iPad删除应用程序，并重新安装它......很奇怪... !!!
