title: I am getting the leak in the following code
body: <p>I am getting the leaks as 100%. I don't know how to release the object after it returns
  Could you explain the procedure how to release the allocated Titles object. </p>
  
  <pre><code>-(Titles *)listTiles
  {
  Tiles* tile = [[Tiles alloc] init];
   tile.googleTile_X = (int)tileX;
   tile.googleTile_Y = (int) pow(2, aZoom) - 1- tileY ;
   tile.zoomLevel = aZoom; 
   return tile;
  }
  </code></pre>
