  <p>I am trying to copy files from one "folder" to "another" in Amazon S3. I can see on Amazon S3 files has been successfully copied but afterward my app crashes with memory error</p>
  
  <p>I can see <code>copyObject</code> is deprecated but I have to copy files so I use it and get following error when I enable zombies;</p>
  
  <p><strong>-S3CopyObjectResponse release: message sent to deallocated instance</strong></p>
  
  <pre><code>//copy request
              S3CopyObjectRequest *copyToNewFolder=[[S3CopyObjectRequest alloc] initWithSourceKey:amazonFileName sourceBucket:[Constants userEventBucket] destinationKey:destinationFile destinationBucket:[Constants userEventBucket]];
                   copyToNewFolder.metadataDirective = @"COPY";
  
              S3CopyObjectResponse *copiedResponse=[self.s3 copyObject:copyToNewFolder];
              if(copiedResponse.error != nil)
              {
                  NSLog(@"Error: %@", copiedResponse.error);
                  return;
              }
  </code></pre>
  
  <p>How can I copy files without getting memory error?</p>
