title: How to reload a table view in a view controller in iPhone?
body: <p>I am new to iPhone development. I have created a table view in a view controller. I want to reload the table view so that I can display the contents which are parsed previously in delegates. More over <code>reloadData</code> does only reload the cells. It doesn't take care of actually updating the underlying datasource.</p>
  
  <p>E.g. if I read data from an array in tableView:cellForRowAtIndexPath:, I have to change the array values before calling reloadData.</p>
  
  <p>How can I achieve this?</p>
