推荐答案

你在 objc_msgSend 中崩溃了。这意味着（如本着名文章中所述）接收器已丢失。在这种情况下，用户似乎点击了一个向目标发送动作消息的按钮，但目标对象已经不存在。

You are crashing in objc_msgSend. This means (as explained in this famous article) that the receiver has gone missing. In this case it appears that the user has tapped a button which sends an action message to a target, but the target object has gone out of existence.
