title: NSInvalidArgumentException - receiver has no segue with identifier
body: <p>I have been trying everything for hours, and nothing's worked. I am trying to segue between two view controllers, from one tableViewController to another tableViewController. The segue is hooked up to the top level view, not the tableviewcell. The identifier that was set in Xcode is identical to the one used in the code (copy and pasted). It was working fine last  night, but now i can't seem to get it to segue without crashing.</p>
  
  <p>here are the methods in which the segue is called</p>
  
  <pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
  {
  
      self.photoList = [FlickrFetcher photosInPlace:[self.topPlacesList objectAtIndex:indexPath.row] maxResults:50];
      NSLog(@"photolist %@", self.photoList);
  
      NSLog(@"here");
  
      [self performSegueWithIdentifier:@"segue1" sender:self];
      NSLog(@"here");
  }
  
  
  -(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
  {
      if([segue.identifier isEqualToString:@"segue1"])
      {
          PhotosTableViewController *photosTVC = segue.destinationViewController;
          photosTVC.photoList = self.photoList;
      }
  }
  </code></pre>
  
  <p>here is the error report</p>
