我的应用程序崩溃，带有nsinternalInconSistencyException

 Exception reason：NSInternalInconsistencyException
        Exception name：Can't cancel on a touch that isn't already active!
        Exception stack：(

    13  libsystem_pthread.dylib             0x0000000190aded8c start_wqthread + 4

如何分析日志？就像这些数字标签是什么意思，" 148" 56" ...？如何检测调用此例外的代码。

这是该应用程序的发行版构建的崩溃，还是在Xcode中使用？如果在XCode中，请提供导致崩溃的代码？

查看您的报告，行

无法取消尚未活动的触摸！

似乎很有说服力。我会查看您与UITouch对象或UIGestureRecognizer进行交互的任何地方。我的猜测是，您正在手动打电话来取消您不应该进行的交互，并且在系统已经取消触摸之后有时会发生这种情况（反之亦然）。
