title: Cancel dropbox loadFile
body: <p>In my app, i allow users to see all their dropbox files, and they can import files into dropbox or download them into the app. I have looked on Dropbox's site but I couldn't find anything on canceling the upload/download. I have some apps (e.g. Textastic) that cancel the dropbox box file transfer, how can i cancel it so it deletes the downloaded data and stops loading into the app?</p>
  
  <p>The code i use to load the file into the app is:</p>
  
  <pre><code>- (void)startDownloadingDropboxFile:(NSString *)dropboxFilePath toPath:(NSString *)destinationPath {
      NSLog(@"dropbox file path: %@",dropboxFilePath);
      NSLog(@"destination path: %@",destinationPath);
      self.dbFilePath = dropboxFilePath;
      [[self restClient] loadFile:dropboxFilePath intoPath:destinationPath];
  }
  </code></pre>
