in your MasterViewController.h 

@protocol CellSelectionDelegate <NSObject>

     -(void)rowSelected:(NSIndexPath *)indexPath;
@end


@interface MasterViewController : UIViewController <UITableViewDataSource,UITableViewDelegate>
{
}
@property(nonatomic,strong)IBOutlet UITableView *menuTable;
@property (nonatomic, weak) id<CellSelectionDelegate> cellDelegate;

@end

in your MasterViewController.m 

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    if([self.cellDelegate respondsToSelector:@selector(rowSelected:)])
    {
        //sending selected indexPath, you can use indexPath.row in your detail view
        [self.cellDelegate rowSelected:indexPath];
    }

}

Now in your DetailedViewController.h

#import "MasterViewController.h"
@interface DetailedViewController : UIViewController<CellSelectionDelegate>
{

}
@property(nonatomic,strong)MasterViewController *masterView;
@end

in DetailedViewController.m

- (void)viewDidLoad
{
    [super viewDidLoad];
    //Set master page as the delegate.
    masterView.delegate = self;

}

Now declare following delegate method

-(void)rowSelected:(NSIndexPath *)indexPath
{
    NSLog(@"Your selected Row : %d",indexPath.row);
    //do your work according to selection made in master view. use indexpath.row to identify which option was selected, you can also pass the other data with rowselected: method
}
