  1. Don't use a slider, use a segmented control. Sliders are for adjusting a single continously variable value. Have the segments named world,continent,state,city,region,10miles and 50miles.
  2. Before displaying the messages, loop through them and set up an array of the messages for each of the options.
  3. Link the segmented control to an IBAction in your view controller. When it gets called, call reloadData on the table view which shows your list of messages.
  4. In your cellForRowAtIndexPath method, use a case structure to select the array from which to assign the text on the cell depending on the value of segmentedControl.selectedSegmentIndex
