Undestanding NSZombie登录

Question

我试图跟踪EXC坏访问。我已经运行了NSZombie启用的仪器，当应用程序崩溃时，我得到这个错误日志。有一个UIView会自动释放四次，但在自动释放池被排空之前，它只有一个引用计数3，所以int以-1引用计数结束。

我不发送任何自动释放的消息我自己，所以我怎么能解决这个问题？

Answer 1

当使用Instruments来分析泄漏时，最好忽略显示归因于Apple库的泄漏。要调查的泄漏是那些显示来源于您的应用程序的代码。当池排出被自动释放

对象被释放。如果您还没有创建自己发布的任何自己的对象，那么唯一的自动发布的对象必须是Apple自己的对象，例如。 [NSString string]。

我假定你已经运行分析和解决突出问题，所有？如果不是，那就是第一步。

接下来，看看那里的EXC_BAD_ACCESS发生线路。它*可能*提供关于违规对象的线索。有可能是 - 或其他 - 对象被过早释放，或者您没有充分保留它们。

发生这种情况时，在某些点上运行时会收回他们。尝试访问它们会导致可怕的EXC_BAD_ACCESS。
