我遇到了来自客户的崩溃,有以下回溯:

8 App 0x0013c9db -[PZTiledImageLayer drawInContext:] (PZTiledImageLayer.m:129)
这是由于应用程序处于后台(不允许)时访问GPU.
导致此崩溃的代码是:
if([UIApplication sharedApplication].applicationState == UIApplicationStateActive)
{
cg_image = [self.imageContext createCGImage:im fromRect:rclip];
}
这意味着应用程序在我检查后更改状态,但在GPU在Core Image …
