Best solution to cache server response is to download the images using NSURLRequest/NSURLConnection, and use proper NSURLRequestCachePolicy to cache response.

To sort out your problem you can use NSURLRequestReturnCacheDataElseLoad cache policy. It will load data from server if there is no cache data locally and if found any local data then returns it without hitting server again.

For more on NSURLRequestCachePolicy and cache server response, you can read here:
