UITableView detail transition

I'm tryin to do a detail list but i can't do it and i don't understand why.

Is a storyboard, the storyboard is connected ok. Is only one tableView and View controller for detail.

I'm trying to push in one cell and go to the detail screen and at the detail class i've two propertys but when i push in a cell, the app crash and i've a exception:

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle (loaded)' with name 'GasolDetalleVCViewController'' *** First throw call stack:

The classes are:

Table Controller .h:

    NSMutableArray *arrayNombrePrecio;
    NSInteger celdaPulsada;
}
@end

#import "GasolTVCTableViewController.h"

@interface GasolTVCTableViewController ()

@end

Thanks a lot

This error can occure when you rename some files outside XCode. To solve it you can just remove the files from your project (Right Click - Delete and "Remove Reference") You re-import the files in your project and everything will be ok !
