UILabel in detail view is not being populated - objective-c

Question

I have a UITableView populated with an array of data gathered from an SQLite database. When a cell is selected a detail view is loaded relevant to that cell. The title on the navigation controller changes ok but a UILabel on the detail view does not get populated.
Relevant tableViewController code:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self.tableView deselectRowAtIndexPath:indexPath animated:YES];
ExhibitorDetailViewController *exhibitorDetailViewControllerInstance = [[ExhibitorDetailViewController alloc] init];
exhibitorDetailViewControllerInstance.theTitle = [self.tableView cellForRowAtIndexPath:indexPath].textLabel.text;
exhibitorDetailViewControllerInstance.exhibitorDetailModal = [arrayOfExhibitors objectAtIndex:indexPath.row];
// Have tried setting the text before the detail view is loaded wiht the line below
exhibitorDetailViewControllerInstance.LabelExhibitorDescription.text = arrayOfExhibitors.description;
[self.navigationController pushViewController:exhibitorDetailViewControllerInstance animated:YES];
}
The viewDidLoad event of the detail view controller:
- (void)viewDidLoad
{
[super viewDidLoad];
self.title = _theTitle; //This sets the title ok
NSLog(#"0 - %#", _exhibitorDetailModal.description); //This property is what I want to fill the UILabel with
self.LabelExhibitorDescription.text = _exhibitorDetailModal.description; // This does nothing
self.view.backgroundColor = [UIColor colorWithRed:0.6 green:0.8 blue:0.8 alpha:2.0f]; // If I don't set the background colour here it loads up black (despite being set in the storyboard)
NSLog(#"label text = %#", self.LabelExhibitorDescription.text); // This shows the text box being null despite having its text property set above
}
Detail view header file:
#interface ExhibitorDetailViewController : UIViewController
{
}
#property (nonatomic, retain) NSString *theTitle;
#property (strong, nonatomic) IBOutlet UILabel *nameLabel;
#property (strong, nonatomic) IBOutlet UILabel *categoryLabel;
#property (strong, nonatomic) IBOutlet UILabel *descriptionLabel;
#property (strong ,nonatomic) NSArray *exhibitorDetailModal;
#property (strong, nonatomic) IBOutlet UILabel *LabelExhibitorDescription;
#end
Why isn't the UILabel text being populated?
Thanks.
Edit:
I have logged the 'outgoing' description of the array - [arrayOfExhibitors objectAtIndex:indexPath.row] and this shows the correct data as expected which is the same as the _exhibitorDetailModal.description which is shown in the detail view.

To get this working in the end I rewrote the entire code and tidied it up along the way.
To get the UILabel displaying properly I first passed the description property of the exhibitorDetailModal object to an NSString.
_stringExhibitorDescription = _exhibitorDetailModal.description;
I then initialised the UILabel.
self.labelExhibitorName = [[UILabel alloc]init];
Then set the text of the UILabel to be that of the NSString above
[_labelExhibitorName setText:_stringExhibitorName];
Then added the UILabel as a subView of UIView.
[self.view addSubview:_labelExhibitorDescription];
