在我的应用程序中，我偶尔会在从其中的GMSMapView（从我的UINavigationController中弹出）中导航离开视图时发生崩溃。它崩溃的螺纹10，和这里的崩溃信息：谷歌地图iOS SDK在销毁GMSMapView时偶尔发生崩溃

有没有人从GMSMapView或谷歌地图SDK见过这样的崩溃？
你能告诉我们你在那个线程中做了什么，如果它是你的？我在编写的代码中遇到类似的崩溃，问题是：我将一个块发布到全局并发队列中;该块创建了一个新的Core Data托管对象上下文，做了一堆事情并退出。发生崩溃是因为一些托管对象通过坐在自动释放池中能够超越该上下文 - 据推测我提供了一个作为返回结果。因此，解决方案是在'@ autoreleasepool'中创建和明确销毁的上下文之间包装所有内容。 – Tommy
线程不是我的。我假设它是谷歌地图检索或更新瓷砖。 –
