我在iOS 8上收到了很多关于此堆栈跟踪的崩溃报告:

大部分都发生在iOS 8.2.0上,而应用程序在后台运行。
我确定在后台工作时,除了setCenterCoordinate
和setRegion
外,mapview不会执行任何操作。
根据Apple Q&A我知道我不应该在后台重绘MKMapView。但是我尝试在后台编程改变mapview的centerCoordinate和region,但它并没有崩溃。
这是iOS 8.2.0的错误吗?有没有办法解决或避免这种情况?谢谢!
答案 0 :(得分:5)
输入背景后,您需要立即停止渲染到任何OpenGL ES曲面。
正如Apple在链接文章中所建议的,使用AppDelegate方法结合NSNotificationCenter ...
