My slide show app loads a large number of images and displays them using CALayer. Occasionally, I get an error message in the log like this:
2023-05-16 16:16:33.606195+0700 MyApp[17514:6600184] IOSurface creation failed:
e00002c2 parentID: 00000000 properties: {
IOSurfaceAddress = 5712560128;
IOSurfaceAllocSize = 52879491;
IOSurfaceCacheMode = 0;
IOSurfaceName = CMPhoto;
IOSurfacePixelFormat = 1246774599;
}
It does not seem to come from my app directly.
I suspect it is caused by CALayer, or could it be caused by
CGImageSourceCreateThumbnailAtIndex())?
Anyways, I am wondering what it means, and I am wondering if I should do
anything about it?
It occurs only for some images, and I haven't found a pattern yet.
Also, it seems to have no effect on my app.
I have googled, of course, but could not find anything helpful.
(The dev docs were also not really helpful in this case.)
