title: play video from URL retrieved from ALAsset in iOS
body: <p>I'm still fairly new to Obj-C and the idea of blocks. I read this post about displaying images from url retrieved from ALAssets: <a href="https://stackoverflow.com/questions/3837115/display-image-from-url-retrieved-from-alasset-in-iphone">display image from URL retrieved from ALAsset in iPhone</a></p>
  
  <p>Besides being able to view picture files in a <code>UITableView</code> using the <code>ALAsset</code> framework, I want to be able to play a video that is stored in the pictures folder as well. The video asset shows up just as a picture would, so I would like to be able to tap that video listing in the table and have it play. (In other words, I want to play a video using the Assets Library Framework) </p>
  
  <p>Can this be done with <code>MPMoviePlayerController</code>? </p>
  
  <p>From that post above I'm gathering I need code inside this function to get an asset URL for a video file:</p>
  
  <pre><code>ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset)
      {
      };
  </code></pre>
  
  <p>If this is right, what code would I need to put inside that function so that I could successfully play the video via <code>MPMoviePlayerController</code>?</p>
  
  <p>Just for reference, my code for displaying the assets in a <code>UITableView</code> is here:</p>
  
  <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
  NSString *CellIdentifier = @"id";
  
      UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
      if (cell == nil) {
          cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
      }
  
  
   [[cell imageView] setImage:[UIImage imageWithCGImage:[[assets objectAtIndex:indexPath.row] thumbnail]]];
   [[cell textLabel] setText:[NSString stringWithFormat:@"Item %d", indexPath.row+1]];
  
      return cell;
  }
  </code></pre>
  
  <p>This is my first post so I'm sorry if I post it wrong. Thanks for your help</p>
