Question

I have an iOS 5 application with a storyboard and two scenes. Scene 1 is a selection list while Scene 2 shows details for each selection

In Scene 1 I need to pass a variable and I do that with:

//Handles the selection 
-(void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{
    Guests *myGuests =[guestList objectAtIndex:[indexPath row]];

    selectedGuest = [[NSString alloc] initWithFormat:@"You have selected %@", myGuests.guestID];

    [self performSegueWithIdentifier:@"TGG" sender:self];
}

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
    if([[segue identifier] isEqualToString:@"TGG"]){
        GuestDetailsViewController *vc = [segue destinationViewController];
        [vc setGuestSelected:selectedGuest];
    }
}

In Scene 2 (details) I use this to verify that the right variable was received like this

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad
{
    NSString *msg = [[NSString alloc] initWithFormat:@"You have selected %@", guestSelected];
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Selection" message:msg delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];          

     nameCell.textLabel.text= msg;

    [super viewDidLoad];
}

All of this works fine and the alert box shows the right variable and there is a transition to the new scene. HOWEVER, the alert box displays a total of 5 times over & over and, once completed, the whole window is black. Nothing from my scene (Scene 2) is displayed at that point. So I know I have the right segue, it transitions as desired, I just can’t see anything on my screen.

Answer 1

i ran into a situation very similar. i had unintentionally un-commented the method:

-(void)loadView

i believe this method overrides the IB interface and created it from this code instead. check to make sure it is either removed or commented out IMHO.
