title: How to dynamically resize UITableViewCell height
body: <p>I have the classical grouped UITableView with editable UITextViews inside every cell. This text views can be single or multi-lined, and I want the cell to increase its height as the user writes and the text starts a new line.</p>
  
  <p>My question is: <strong>do I need to reload the whole table just to increase the height of a cell? Isn't there any other method?</strong></p>
  
  <p>I've been searching a lot, and previous answers and tutorials just talk about how to calculate text height, how to implement heightForRowAtIndexPath... things that I already know. My concern is that, to achieve what I want, I will have to calculate height and reload the table every time the user enters a new character, which I don't find very clean or efficient.</p>
  
  <p>Thanks.</p>
