  I tried using UISearchController but also have same problem
  i used this code <a href="https://github.com/dempseyatgithub/Sample-UISearchController" rel="nofollow noreferrer">link</a><br></p>
  
  <p>I add below code in TPSMastreViewController.m</p>
  
  <pre><code>- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
  {
      UIView *v = [[UIView alloc] init];
      v.backgroundColor = [UIColor greenColor];
      return v;
  }
  </code></pre>
  
  <p><hr>
  I checked that delegate - (UIView *)tableView:(UITableView *)tableView<br>
  viewForHeaderInSection:(NSInteger)section<br>
  is not called in the case of iOS8.<br>
  <strong>Edit :</strong><br>
  What i understand is only UITableViewDataSource delegate is called, UITableViewDelegate did not.<br>Please not that i set both delegate in ViewDidLoad
  <br>
  <strong>Question :</strong><br>
  1] Is it an UI change ? <br>
  2] Any one have patch so that delegate method will call forcefully.</p>
