Based on your code from the chat, you need to thoroughly check your code for memory leaks and performance problems. It is littered all over the place.

That put aside, make the following changes to give your code a chance to work:

-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText{
  if(searchBar.text.length == 0) {
    [searchDict removeAllObjects];
    [arrayDict removeAllObjects];
    [self getJsonResponse];
    } 
  else {
    [arrayDict removeAllObjects];
    [self getSearchJsonResponse:searchBar.text];
    }
}

Also, wrap [self.tableView reloadData] in a dispatch to the main queue in your web services' completion blocks like so:

dispatch_async(dispatch_get_main_queue(), ^{
   [self.tableView reloadData];
});

Additionally, what does NSLog(@"SEARCHDICT::%@",searchDict); log? Could it be possible that your lack of errorhandling is swallowing up a failed web service call response (like, empty search bar or 'I'm not searching for length 1')?
