自iOS 9以来,VectorKit/OpenGL在MKMapView中崩溃

Question

我可以从Crashlytics看到我的一些应用程序用户遇到以下崩溃.我自己从未见过这些,也不知道如何重现它们,因为它们在堆栈跟踪中没有我的代码.我已经读过OpenGL,当应用程序在后台时尝试更新表面时,可能会发生一些崩溃.不确定这是否是这种情况,因为在iOS 9之前没有发生崩溃.

我在地图上有几个注释,自定义MKAnnotationView派生视图,一些自定义叠加和MKTileOverlay派生的tile源.地图处理代码和叠加层是Objective-C,但我的应用程序也有一些Swift代码.

有没有人有任何想法可能是崩溃的原因？

Answer 1

1. 我的应用程序中的类似崩溃日志如下。从线程名称“com.apple.maps.geogl.renderQueue”来看，我猜测这与MapKit框架的使用有关。

2. 我在技术 QA 中找到了“gpus_ReturnNotPermissionKillClient”：“如何修复移动到后台时 OpenGL ES 应用程序崩溃” https://developer.apple.com/library/archive/qa/qa1766/_index.html
