我需要MKMapView崩溃的帮助

Question

我的实时应用程序最常发生的崩溃之一是MKMapView崩溃.它在内部方法崩溃-[MKMapView mapTileViewDidFinishLoading:].在我的测试期间,我无法追溯崩溃,但在iTunes Connect的崩溃报告中非常频繁.今天有任何关于此次崩溃的经历吗？它只是一个非常简单的地图,只显示一个注释.

以下是此崩溃的完整堆栈跟踪:

我想我可能已在我自己的应用程序中解决了这个问题.看来这篇文章有正确的解决方案和解释.

在我的应用程序中导致失败的消息是'mapViewDidFinishLoadingMap',它是MKMapViewDelegate的消息.尝试在view dealloc方法之前将mapView委托设置为'nil'.
