How to make a dynamic row addition when the user has reached the last row of a UITableView?

I have UITableviewone that shows 10 lines currently that are motionless. Now I want to add a function to it. I want to add more than 10 rows to the table when the user reaches the last row UITableview. I mean, I'm currently showing fixed 10 lines in the application.
