推荐答案
是的，这可能是一个AFNetworking错误（固定在2.5.0），很可能。具体来说，这一个：

的https：/ /github.com/AFNetworking/AFNetworking/issues/1477
如果没有，那么它可能是类似的 - 一个关键值观察者试图观察一些URL会话任务的方面已被释放，并且在被释放之前未停止观察该任务。
If not, then it is probably something similar—a key-value observer trying to observe some aspect of a URL session task has been deallocated and didn't stop observing that task prior to being deallocated.
