我的自动释放池随机崩溃了我的应用程序，此问题的常见原因是什么？

我知道这是因为一个对象被过度释放，我认为在自动释放池尝试释放它之前对象被释放是正确的吗？因此自动释放池试图过度释放对象？
My autorelease pool is crashing my app at random, what is the common cause of this problem?

I know this is because an object is being over released, am i correct in thinking an object is being released before the autorelease pool is trying to release it. Therefore the autorelease pool attempts to over release an object?

你的评价是正确的。尝试使用模拟器中的“Zombies”工具运行您的应用程序，或将 NSZombieEnabled 环境变量设置为 YES。这些都将为您提供有关哪些对象被过度释放的更多信息。
Your assessment is correct. Try running your app using the "Zombies" instrument in the simulator, or setting the NSZombieEnabled environmental variable to YES. These will both give you more information about what objects are being overreleased.
这是因为额外的内存释放。不要释放在自动释放池中分配并从拥有自己的内存的对象初始化的对象。这可能是这背后的一个原因，因为我也遇到了这个问题。
This will be because of extra memory releases. Do not release the object which is being allocated inside auto-release pool and is inited from object which has its own memory. This may the one reason behind this as i also faced this problem.
