随着iOS13的发布,我们正在开发的应用程序上有越来越多的mapKit VectorKit崩溃。我们无法在内部重现崩溃,并且我们自己的崩溃报告者每天收集超过200个崩溃。
根据我们获得的所有信息,当应用程序从后台激活时,崩溃总是发生,并且那时,ViewController视图具有MKMapView
子视图。系统渲染地图UI时可能出了点问题。
此问题自iOS11或更早以来似乎是一个持久的iOS问题。现在,与崩溃相关的iOS13系统版本包括13.0
,13.1
,13.1.1
,13.1.2
。我已经在Apple Bug报告系统上报告了该问题,但是到目前为止,Apple没有任何响应。
任何建议或提示将不胜感激。
仅供参考。崩溃堆栈如下。

检查您在iOS12和iOS13上的CPU使用率。
[我注意到我的应用程序崩溃是因为我过于频繁地在地图上添加和删除折线(尽管此问题仅在iOS13而不是iOS12中有所体现。
请参阅我关于此here的SO帖子。
查看您的崩溃日志,看看是否发现了这样的内容:
