The RSIZE of MyGame is only 23.6MB, but the "Memory status: 11" indicate that the program recieves a shutdown command from OS due to memory problem. MyGame的RSIZE只有23.6MB，但是“内存状态：11”表示该程序由于内存问题而从OS接收到关机命令。

So if the memory problem is not caused by my program, is there any way to ignore the shutdown command post from OS? 因此，如果内存问题不是由我的程序引起的，有什么方法可以忽略OS中的shutdown命令吗？

And from the iPhone develop guide, the OS will terminate a bg process which enconters a memory problem. 根据iPhone开发指南，操作系统将终止bg进程，这会引发内存问题。 But the SpringBoard is not terminated. 但是SpringBoard没有终止。 So I think there should be a method to turn the memory management off in program. 所以我认为应该有一种方法可以在程序中关闭内存管理。

You can't ignore the memory warning. 您不能忽略内存警告。 The best you can do is try to free up some memory and hope your app doesn't get killed. 您能做的最好的事情就是尝试释放一些内存，并希望您的应用不会被杀死。
