由于，iOS应用程序崩溃
我从Crashlytics收到了以下报告。 我自己没有调用[UIFeedbackGenerator _autoDeactivate] 。 也许有些图书馆正在这样做。 我做了一些研究，但找不到任何有用的信息。 有谁知道这个崩溃报告意味着什么？ 谢谢！
致命exception：NSInternalInconsistencyException
自动停用对于样式2：强制停用，样式为TurnOn且未激活（activationCount = -1）配置： activationCount：-1，styleActivationCount：-1 engines：{（）}
这是完整的报告：

我有同样的问题，你可以检查以下步骤：
-
cd到项目的根路径 -
跑
grep -r UIFeedbackGenerator .
然后你会发现哪个库正在使用UIFeedbackGenerator 。
希望这会帮助你。
