By "launching app from killed state," do you mean a cold launch, like the first one after the Simulator is opened?

I mean by launchinfg app when its not running in background, after launch. But not in simulator on device, iPhone 6. This crash is not always reproducible, is it has to do something with the 3x images because i hve 2x image but not 3x in my bundle.

Did you look at whatever image is being loaded in the problem code? You might also want to crack open a compiled build of your app to make sure that all of the resources made it into the bundle. (Unless you use asset catalogs, in which case you can't see the compiled resources.)


At this point, I'm pretty sure it's a bug within iOS, so you should probably go ahead and file a bug report (here's the link if you need it: bugreport.apple.com). So all we're doing now is attempting to isolate the problem so that it can be reproduced and eventually figure out a workaround. Be sure to keep your bug report updated with new information as you discover it.

I am experiencing a similar issue on an iPad app. The crash is sporadic but I've isolated it to [UIImage imageNamed]. I had set an malloc_error_break breakpoint and it appears the cached UIImage that's being loaded has been released. When I change from imageNamed to initWithContentsOfFile, the crash no longer occurs. It appears to be a bug with the caching/purging system of imageNamed.
