我正在使用这个堆栈跟踪在iOS 8上收到很多崩溃报告：

大多数情况发生在iOS 8.2.0,而应用程序在后台运行.
在背景中,除了setCenterCoordinate和setRegion之外,我确定没有对mapview执行任何操作.
根据Apple Q&A我知道我不应该在后台重新制作MKMapView.但是我在程序上尝试改变mapview的中心坐标和区域,但并没有崩溃.
解决方法
一旦您进入背景,您需要停止渲染到任何OpenGL ES Surface.
正如Apple在链接文章中所提到的,使用AppDelegate方法与NSNotificationCenter结合使用…
看看this answer参考…
