I have an app that is basically a slide show. Basically, it loads one image after another, displays it, then frees up its memory. When I test it with my image collection of 100k+ images, everything is fine.
However, one user sent me a photo (JPG) that makes my app use up more and more memory. I can see it in Activity Monitor and in Xcode's Memory Report View. After a minute, my app uses 5 GB of main memory, after that, the growth rate slows down a bit, but it keeps growing without bounds, until, eventually, it crashes, of course. However, when I try to check for memory leaks using XCode/Instruments/Leaks, it says there are none! Is it possible there is a memory leak in Apple's frameworks? If you are interested, you can find the image here: https://owncloud.informatik.uni-bremen.de/index.php/s/BbBJcjMSTm9enwW It's just 5 MB, and I can't see any issue with it. The uncompressed image in-memory maybe takes up 100MB. The frameworks/methods I use are the usual: CGImageSourceCreateWithURL() for loading, CALayer for displaying. I assign the image like this: CALayer * imgLayer = [CALayer layer]; imgLayer.contents = (__bridge id)(imageRef); where imageRef is of type CGImageRef. I also release my images later with CGImageRelease(). I am a stymied. Any hints/suggestions will be highly appreciated. Gab.
