我在 map 上选择标记时发生随机崩溃。您在代码中看到的标记是自定义的，当点击它们时，标记的图标将被隐藏，并放置自定义信息 View 。 所有委托(delegate)方法每次都会正常执行，因此崩溃并不直接在我的代码中，但我可能会做一些“扰乱”谷歌地图的事情

markerInfoWindow 委托(delegate)方法的描述说我应该避免更改超过 500x500 px 的 map 大小并避免更改标记，我已经删除了所有标记的调用，但它还是崩溃了 我尝试检查我是否在主线程上使用了mapView，我用[NSThread currentThread]检查了它，它似乎总是在主线程中，请让我知道是否有更好的方法来检查它

解决了崩溃问题
我不太清楚为什么，但是修改图层的属性使用了 CoreAnimation，并且可能会使用他自己的线程来更改它，从而为 Google 的 API 生成不稳定的状态
关于ios - 选择标记时 Google-Maps-iOS-SDK 崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29150939/
