Question

我关注＆＃34; https://segment.com/＆＃34;在我的iOS源上实现分析用户使用情况。但是，当我使用UIAlertController来显示带有标题的警报是@＆＃34;＆＃34;时，我的应用程序崩溃了！我不确切知道为什么。要解决它，我必须设置警报标题为零。这是我的日志：

libc++abi.dylib: terminating with uncaught exception of type NSException

Answer 1

我在使用Segment框架时遇到了同样的问题。

我只是在SDK文件中为空屏幕注释Assert语句。请在整个项目中搜索下面的行，并将其评论出来。

NSCAssert1（screenTitle.length＆gt; 0，@“屏幕名称（％@）不能为空。”，screenTitle）;

你很高兴。

Answer 2

这似乎是错误Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'screen name () must not be empty.

确保您在创建SEGAnalytics课程或相关内容时已经设置了
