2. 1 Performance: App Completeness
Guideline 2.1 - Performance - App Completeness
We were unable to review your app as it crashed on launch. We have attached detailed crash logs to help troubleshoot this issue.
给了崩溃日志
1.我在真机和模拟器iOS13系统测试并没有崩溃，用testFlight测试才有崩溃
2.需要符号化日志，参考：

我符号化以后还是看不懂，然后我在友盟的错误分析上找到了崩溃日志
UISearchDisplayController is no longer supported when linking against this version of iOS. Please migrate your application to UISearchController.
但是搜代码里并没有UISearchDisplayController，搜SearchDisplay找到问题，原来是之前的StoryBoard里用了UISearchDisplayController但是没有删除干净，iOS13不能用UISearchDisplayController了
参考：https://github.com/mapbox/mapbox-gl-native/issues/15559
改完以后用testFlight测试，可以正常启动，但是运行一段时间又崩溃了，用友盟查看错误日志，
+[_LSDefaults sharedInstance]: unrecognized selector sent to class 0x1ef61aff8
(null)
查找以后发现是友盟的问题，需要更新框架
pod 'UMCCommon', '~> 2.1.1'
pod更新以后再测测试，终于不崩溃了
