title: Filtering sections of a table view using a segmented control
body: <p>I'm wondering what the best way is to filter out various sections in a table view using a segmented control in a toolbar.  </p>
  
  <p>Let's say, for example, I have a table view with cells in 3 different sections - Friday, Saturday, and Sunday. I also have a toolbar on top of the view with 4 segments - All, Friday, Saturday, and Sunday.  When 'All' is selected on the segmented control, all sections and cells in the table should be displayed.  When 'Friday' is selected on the segmented control, only cells in the Friday section should be displayed in the table.  And so on and so forth...</p>
  
  <p>Where in the code for my table view controller can I make this happen?  I imagine it's a pretty simple thing to achieve, so are there any other examples of this that somebody can point me to?</p>
  
  <p>Thanks in advance!  </p>
