title: SDWebImage UIImageView+WebCache crashing on 64 bit devices
body: <p>I have this code:</p>
  
  <pre><code>#import &lt;SDWebImage/UIImageView+WebCache.h&gt;
  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
  [cell.thumbnail setImageWithURL:[NSURL URLWithString:thumbnailURL] placeholderImage:[UIImage animatedImageWithImages:loadingArray duration:1] options:indexPath.row == 0 ? SDWebImageRefreshCached : 0];
  }
  </code></pre>
  
  <p>where "loadingArray" is just an array of png images. cellForRowAtIndexPath obviously has a lot more code.</p>
  
  <p>This code works on 32 bit devices and emulator on 32 bit, but it crashes on 64 bit devices and 64 bit emulator.</p>
  
  <p>Here's the crash report from XCode:</p>
  
  <pre><code>-[UIImageView setImageWithURL:placeholderImage:options:]: unrecognized selector sent to instance 0x110942780
  *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIImageView setImageWithURL:placeholderImage:options:]: unrecognized selector sent to instance 0x110942780'
  </code></pre>
  
  <p>I am using the SDWebImage-3.6 framework re-downloaded today (Apr. 22 2014)
  Cleaned the project, re-added the app to the emulator...same issue.</p>
  
  <p>Any suggestion to fix this issue would be highly appreciated.
  Thank you.</p>
