title: Dynamically add and remove UITableViewCells to UITableView
body: <p>I'm building an app where a user is able to provide different usernames that he/she has. The vision is, the user is able to add and remove UITableViewCell to enter a username.</p>
  
  <p>Right now I have a grouped UITableView and on the right hand side of every UITableViewCell I have a UIButton that adds another cell to the table with a UITextField. After the first cell, every cell has a delete button. I'm trying to make the UIButton delete that row. I have the IBAction that removes the cell, the only problem is, it's not deleting the proper row.</p>
  
  <p>What is the best way to do what I'm attempting to do? I don't know how to properly search for this on Google. I'm sure someone has done what I'm trying to do.</p>
  
  <p>Thanks for any help in advance!</p>
