推荐答案
你在 objc_msgSend
中崩溃了。这意味着(如本中所述)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.
