AFNetworking's AFImageRequestOperation cannot find cached images sometimes

[burakkilic]

Hi;

I am using SDURLCache like this:

SDURLCache *urlCache = [[SDURLCache alloc] initWithMemoryCapacity:1024*1024 * 20
                                                     diskCapacity:1024*1024*20 
                                                         diskPath:[SDURLCache defaultCachePath]];    
[urlCache setIgnoreMemoryOnlyStoragePolicy:YES];
[NSURLCache setSharedURLCache:urlCache];

And for image request:

NSURLRequest *imageRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:c.imagePath] cachePolicy:NSURLRequestReturnCacheDataDontLoad timeoutInterval:30.0];
AFImageRequestOperation *operation = [AFImageRequestOperation imageRequestOperationWithRequest:imageRequest
                                                                                  imageProcessingBlock:nil
                                                                                             cacheName:@"nscache"
                                                                                               success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image){                                                                                                                                                                                                   imageview.image = image;
                                                                                               }
                                                                                               failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error){ NSLog([error description]); }
                                              ];
        [operation start];

With these codes, sometimes all of my images are cached and successfully retrieved from the cache. But sometimes, some images cannot be displayed. How can I find the problem?
