ios - 缩放或平移时，mapview 因许多折线而崩溃

Question

有人可以帮我找出问题所在吗？

2 年前我发现其他人也有同样的问题 :( 请参见此处： 在 MKMapView 上使用叠加层进行缩放时出现异常：NSInvalidArgumentException NSSetM removeObject: object cannot be nil

我不会在主线程中添加或删除一些东西。

该应用程序有时运行 7 小时没有问题。通过大量缩放或平移，我可以强制应用程序失败。

示例堆栈：

* 由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“* -[__NSSetM removeObject:]: object cannot be nil”
