It takes a long time to view the table to update after "reloadData ()"

Question

This is what I am trying to do: Get xml from Apple RSS containing application information, parse it and show the applications as UITable.

The problem is that after "reloadData ()" it takes about 5 seconds until the information appears. In addition, the application always crashes on its first launch after opening a project.

here is the project: http://www.mediafire.com/?2dn6g916bh9uf4v
