ARC forbids explicit message send of 'release'

[nfs3250]

I am integrating the SDURLCache with AFNetworking in my iOS app. I called below metho in appDidFinishLaunching method
#pragma mark - Use Custom URL Cache

      -(void)useCustomURLCache
      {
             SDURLCache *urlCache = [[SDURLCache alloc] initWithMemoryCapacity:1024*1024   // 1MB mem cache
                                                     diskCapacity:1024*1024*5 // 5MB disk cache
                                                         diskPath:[SDURLCache defaultCachePath]];
             urlCache.ignoreMemoryOnlyStoragePolicy = YES;
             [NSURLCache setSharedURLCache:urlCache];

        }

I am getting below error in SDURLCache.m file
ARC forbids explicit message send of 'release'

Can you help me with this ? Thanks

That needs to be conditionalized for iOS6 dispatch object changes. Feel free to submit a pull request or lower your target to iOS5.
