It's not a good idea to rely on the cell+textfield to be the backing-store for your data. The reason is that the UITableView will recycle those cells as the user scrolls through the list. The only way you can reliably do this is if you allocate/init each cell once and manage them all in an array, from which you retrieve the correct cell when the tableview calls cellForRowAtIndexPath:. But this is a bad idea if you have a lot of rows. If you have only a few rows it can be a fine idea, and then you can simply traverse your array to access each cell/textfield.

Otherwise you need to implement the text field delegate method to capture when the field contents change, in any given cell. When they do, you can grab the field contents and store the value in your backing store. You might consider setting the textField tag to be it's row-index - this is a simple way to know which textField is being updated when your delegate method is called.
