iphone - iphone: initialize part of a nib file multiple times

Question

I design my UITableView by Interface Builder.

I can use a separate nib file for UITableViewCell, but not so convenient for me.

So, I want to have my custom UITableViewCell in the same nib file (another object in the same level with UITableView's object)

Do you know how to initialize custom UITableViewCell object many times, efficiently way?

Thanks
