title: Objc save a file to the tmp/ with URL it is not working
body: <p>if i do the following it works fine </p>
  
  <pre><code>NSString *filePath = [NSTemporaryDirectory() stringByAppendingPathComponent:[response suggestedFilename]];
  </code></pre>
  
  <p>But if i try to save it using the URL (although it returns the correct path) it does not save it. </p>
  
  <pre><code>NSString *filePath = [NSTemporaryDirectory() stringByAppendingPathComponent:[[response URL] absoluteString]];
  </code></pre>
  
  <p>Any ideas?</p>
