title: Hide or remove section from uitableview
body: <p>i am implementing a grouped table view in my application, where user can select row from different section of table.</p>
  
  <p>i want to hide(remove) particular section(including header) depending upon selection of row of first section.</p>
  
  <p>i.e.</p>
  
  <p>first sections header is "Do you own car?", answer would be YES or NO in row selection.
  if user selects NO, second and third section from grouped table should hide(remove).</p>
  
  <p>for radio selection in grouped table, i implement <a href="http://walkingsmarts.com/creating-radio-button-and-checkbox-lists-using-uitableview/" rel="nofollow noreferrer">this</a></p>
  
  <p>i also refer <a href="https://stackoverflow.com/questions/1061071/uitableview-deleting-sections-with-animation">this</a> but does not full fill what i need.</p>
  
  <p>Please help.</p>
  
  <p><strong>Edit</strong></p>

  <p>myArray is my datasource.
  myArrayAnswerCount contains count of number of row per section</p>
  
  <pre><code>-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
      return [myArray count];
  }
  
  -(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
      for (int i = 0; i&lt;[myArray count]; i++) {
          if (section==i) {
              return [[myArray objectAtIndex:i] title];
          }
      }
  }
  
  -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
      for (int i = 0; i&lt;[myArray count]; i++) {
          if (section==i) {
              return [[myArrayAnswerCount objectAtIndex:i] intValue];
          }
      }
  }
  </code></pre>
  
  <p>this is code for how i removes section from table,
  myIndexPath is NSIndexPath variable which is pointing to section which is currently selected.</p>
  
  <pre><code>[table beginUpdates];
  [myArray removeObjectAtIndex:myIndexPath.section];
  [table deleteSections:[NSIndexSet indexSetWithIndex:myIndexPath.section] withRowAnimation:YES];
  [table endUpdates];
  </code></pre>
