title: prepareForSegue called before didSelectRowAtIndexPath only when third segue is added
body: <p>I have 3 segues to 3 different views.  2 are implemented with no problem, it is when the third is created that the problems occur.</p>
  
  <p>I have the following didSelectRowAtIndexPath method:</p>
  
  <pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
      NSLog(@" ----------  did select row");
  
      if(indexPath.section == 0){
          if(indexPath.row == [self.data count]-1){
              //prior to adding this, everything works
              [self performSegueWithIdentifier:@"MoreComments" sender:self];
          }else{
              [self performSegueWithIdentifier:@"FriendView" sender:friend];
          }
      }else if(indexPath.section == 1){
          if(indexPath.row == [self.data2 count]-1){
              [self performSegueWithIdentifier:@"MorePosts" sender:self];
          }else{
              [self performSegueWithIdentifier:@"FriendView" sender:friend];
          }
      }
  }
  </code></pre>
  
  <p>I have the following prepareForSeque method:</p>
  
  <pre><code>-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
      if([segue.identifier isEqualToString:@"MorePosts"]){
          MorePostsViewController *mfamvc = segue.destinationViewController;
          mfamvc.data = self.data;
      }else if([segue.identifier isEqualToString:@"FriendView"]){
          FriendViewController *fvc = segue.destinationViewController;
          fvc.friend = friend;
      }else if([segue.identifier isEqualToString:@"MoreComments"]){
            MoreCommentsViewController *mcvc = segue.destinationViewController;
            mcvc.data = self.data2;
      }
  }
  </code></pre>
  
  <p>Before control dragging from my cell to the last view I can see that my program hits didselectrow and then prepareforseque.  This makes all the view navigation work perfect.</p>
  
  <p>As soon as I control drag from my cell to the MoreCommentsViewController I start to see the error:  </p>
  
  <p>nested push animation can result in corrupted navigation bar
  Finishing up a navigation transition in an unexpected state. Navigation Bar subview tree might get corrupted.</p>
  
  <p>I notice that now also prepareforseque is being called twice, with prepareforseque being called first, then didselectrow, then prepareforsegue again.</p>
  
  <p>What am I doing wrong to conditionally go to these different views?</p>
