iOS 7 MapKit崩溃：[VKRasterOverlayTileSource invalidateRect：level：]中的EXC_BAD_ACCESS [英] iOS 7 MapKit Crash: EXC_BAD_ACCESS in [VKRasterOverlayTileSource invalidateRect:level:]

问题描述

我只在iOS 7上发生了不可重现的崩溃。我正在大量使用MKOverlayRenderer在地图上绘制形状。这种崩溃在iOS 6上不会发生。

I have an unreproducible crash on iOS 7 only. I'm making heavy use of MKOverlayRenderer to draw shapes on the map. This crash does not happen on iOS 6.

任何与此相关的想法都会有用。

Any ideas of what this might be related to will be useful.

推荐答案

我发现了我的问题。可能它也解决了你的问题...在dealloc中，删除所有的MapViews叠加层并且应该修复崩溃......

I found my problem. Might be that it solves yours too... In dealloc, remove all of the MapViews overlays and the crash should be fixed...
