我在报告中显示doesNotRecognizeSelector的自定义键盘扩展程序崩溃了，但崩溃的代码并不是我的......它在基金会中/的CoreFoundation。这是崩溃报告......

我可以在第2行看到doesNotRecognizeSelector，而堆栈中最近的东西是NSExtensionContext _willPerformHostCallback。我查看了报告中的所有主题，并且没有显示任何代码中的内容。我搜索了我们的代码库，但是我没有看到任何代码覆盖willPerformHostCallback或从NSExtensionContext派生的任何代码。
有人能看到这笔交易是什么吗？
TIA，迈克
