这个问题一般是由于程序访问了不存在内存地址造成的崩溃

解决步骤：

1、找到当时上传代码时使用的DYSM文件，这文件通常在.xcarchive文件中。 右键该文件， 然后通过终端工具跳转到下面的DWARF文件夹中：

2、找到左边列是你的app名字的几列 看对应的右面内存地址并依次执行 。我的是arm64的cpu报错，所以下面用arm64，如果其他的是armv7或armv7s 相应的更改就可以
$ atos -arch arm64 -o Lazy 0x10014f98c

$ atos -arch arm64 -o Lazy 0x10014f058

$ atos -arch arm64 -o Lazy 0x100257eb0

……

有几个执行几个，并依次记录打印结果

就可以看到这处内存地址反编译回来的源码行，可以有效地帮助分析原因。 
注意，如果定位到的地址是UmengSignalHandler，要知道这个不是错误，是捕捉crash的方法，本身不引起crash， 当crash发生时由它来捕捉，直接忽略crash log中的 UmengSignalHandler 部分即可。

注：

如果没有打印出源码行日志，出现类似

atos cannot load symbols for the file Lazy for architecture armv7.
这样的打印说明你的$ atos -arch arm64 -o Lazy 0x100257eb0  这个命令可能cpu类型不对或者内存地址不对
