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：
http://www.cocoachina.com/articles/20921
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
