苹果拒绝我的应用程序，由于崩溃，无法重现
我刚上传了一个应用程序到appstore，它是为ios7开发的。
他们拒绝了应用程序，因为我无法重现崩溃…他们给我发了这个崩溃报告：

你用EXC_BAD_ACCESSexception崩溃了EXC_BAD_ACCESS 。 根据我的经验，这可能意味着一个对象已经超出了范围，而您正在尝试访问它，或者该对象应该在另一个线程上做某件事情，同时（当它正在这样做时），它已经退出范围在原来的线程。
如果您正在使用Apple的multithreading对象（几乎所有使用委托callback的对象），请确保它被包含在其中的对象保留（ strong ）。 例如，如果您使用的是asynchronouscallback对象，则不能只是在方法中实例化，然后让它消失，您必须使其成为一个strong @property因此即使在方法返回时它仍然在作用域中，而您正在等待callback。
编辑（基于CFSocket线程） ：
从它的外观来看，你正在使用一个通常与NSStream类一起使用的套接字API。 请记住为那些NSStream对象（或其他正在使用的连接对象）创build强大的NSStream ，并且如果将它们包装到另一个对象中，请确保它是一个strong @property （无论使用哪个对象）。 您不能从创build它的线程上不存在的对象获得asynchronouscallback。
（注意，这不仅仅是一个消息对象被设置为nil ，消息到nil不会崩溃，只是返回nil 。问题是一个消息被发送到内存中的东西，你不拥有了） 。
编辑2（基于主线程） ：
你确定你拥有在View Controller转换中使用的每个对象吗？ 在块或asynchronous操作中创build瞬态对象也可能导致EXC_BAD_ACCESS 。
从它看起来，可能是两个线程正在访问相同的variables，其中一个线程正在破坏另一个线程中使用的variables。 这是一个同步问题。 糟糕的访问通常意味着你正在访问一个variables是零
您可以在您的应用程序中集成崩溃报告工具，如www.crashlytics.com 。 这是非常容易实现和文档是可用的，一旦你下载SDK。 实施后，testing你的应用程序，它会告诉你代码崩溃的确切行，你可以解决它。
