Issue

I was trying to load imageUrl from firestore and load it to my application. Initially i tried to load around 4 or 10 images and it works fine. But when i want to load around 20 images and my app crashes and it also shows error in my console states that Message from debugger: Terminated due to memory issue .

@SamboVisal thanks for taking the time do describe the issue. We had similar issues in the past, usually because the iOS system cannot handle decompressing of many images at once, due to the memory spike that causes an out-of-memory crash. You can look at similar issues here: https://github.com/rs/SDWebImage/search?q=Terminated+due+to+memory+issue&type=Issues

One thing you can try is disabling the decompression:

[[SDImageCache sharedImageCache] setShouldDecompressImages:NO];
[[SDWebImageDownloader sharedDownloader] setShouldDecompressImages:NO];

Also check out these points about reducing the memory footprint: #2252 (comment)

One thing I recommend is just running the app through instruments and inspecting the memory.

Thank for your reply. I will try to fix this. But i have another question, when images are loading and i have seen some images are in not correct order and some images are duplicate in different cells. But after, images are loaded successfully then all images are in correct order. I wonder why?

@SamboVisal regarding the other issue, it would have been ideal to have a separate issue. But I can respond here: we also had similar issues: https://github.com/rs/SDWebImage/search?q=wrong+image&unscoped_q=wrong+image&type=Issues
I suggest you take a try with this suggestion: #968 (comment)
