Ios 生产应用程序上的EXC#u坏访问崩溃，It'；5%的用户出现了这种情况，但我无法重现

保留周期是否会导致内存泄漏，或者在某个时间点也会导致不正确的访问

我的应用程序有时会在prod上崩溃，调试时我无法再现崩溃。我猜崩溃是由于并发，但同时我发现了一个保留周期，但我认为它不会导致崩溃，它可能只是泄漏

有人能从下面的崩溃日志中猜出确切的问题吗

EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x00000009f34b81e0

如果您没有使用Crashlytics或类似的工具，我建议您这样做……实施Crashlytics以获得崩溃的适当详细信息日志来自crashlyticsEXC\u BAD\u ACCESS KERN\u INVALID\u ADDRESS指示了悬空指针错误。某个地方有一个解除分配的对象仍然被引用，而您试图取消引用它，因此出现了错误。这可以在retain cycle设置中找到，在该设置中，您尝试强制展开已解除分配的弱父级。
