How to display data from TableView on a DetailsView - ios

Question

I have a HomeTableViewController which consists of two sections. When you click on ANY cell, it directs the user to the DetailsViewController. The DetailsViewController has 2 labels. One in the cell number, the other is the due date. To direct my cell to my details view controller I have the following code: This is in my HistoryTableViewController.m
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// HistoryDetailsViewController *HDV = [self.storyboard instantiateViewControllerWithIdentifier:#"HistoryDetails"];
// [self.navigationController pushViewController:HDV animated:YES];
NSLog(#"index path section--%i",[indexPath section]);
[self performSegueWithIdentifier:#"Push" sender:indexPath];
}
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if ([[segue identifier] isEqualToString:#"Push"]) {
HistoryDetailsViewController *detailVC=(HistoryDetailsViewController*)segue.destinationViewController;
}
}
Now that I'm able to access my DetailsViewController, I want to control its labels. I want to be able to modify the labels ACCORDING TO THE SECTION OF THE CELL I TAPPED ON.
However when I try something like
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if ([[segue identifier] isEqualToString:#"Push"]) {
HistoryDetailsViewController *detailVC=(HistoryDetailsViewController*)segue.destinationViewController;
detailVC.labelCellNum.text = #"Cell test";
detailVC.labelDueDate.text = #"Date Test";
}
}
I can't even modify the label's text using this code. I don't understand.
All help is appreciated, thanks in advance.

The way I would do it would be to have a property for each string you'd like to use in the detail view: (declared in .h)
#property (nonatomic, strong) NSString *stringOne;
Then in the prepareForSegue, I would assign a certain value to it:
[detailVC setStringOne:#"Some string"];
And in the viewDidLoad method of the Detail VC, I'd set that string somewhere I want to use it:
[self.labelCellNum setText:self.stringOne];
