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. 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试图释放它之前正在释放一个对象是正确的。 Therefore the autorelease pool attempts to over release an object? 因此，自动释放池会尝试过度释放对象？

Answer 1

Your assessment is correct. 您的评估是正确的。 Try running your app using the "Zombies" instrument in the simulator, or setting the NSZombieEnabled environmental variable to YES. 尝试使用模拟器中的“Zombies”仪器运行应用程序，或将NSZombieEnabled环境变量设置为YES。 These will both give you more information about what objects are being overreleased. 这些将为您提供有关哪些对象被过度释放的更多信息。

Answer 2

This will be because of extra memory releases. 这将是因为额外的内存释放。 Do not release the object which is being allocated inside auto-release pool and is inited from object which has its own memory. 不要释放在自动释放池中分配的对象，并从具有自己的内存的对象中提取。 This may the one reason behind this as i also faced this problem. 这可能是我背后的一个原因，因为我也遇到了这个问题。
