From this ViewController.m I want to invoke updateTable in LeftViewController.m

gistfile1.m

//---------------------------------------ViewController.h---------------------------------------

@protocol LeftViewControllerProtocol <NSObject>

-(void)updateTable;

@end


@interface ViewController : UIViewController <CLLocationManagerDelegate,ViewControllerDelegate>
{
  
}

@property (nonatomic,strong) id <LeftViewControllerProtocol> leftViewControllerProtocol;



//---------------------------------------ViewController.m---------------------------------------

@implementation ViewController

@synthesize leftViewControllerProtocol;
@end

//---------------------------------------LeftViewController.h---------------------------------------

#import "ViewController.h"
@interface LeftViewController : UITableViewController <LeftViewControllerProtocol>
{

}

-(void)updateTable;
@end

//---------------------------------------LeftViewController.m---------------------------------------


- (void)viewDidLoad
{
    [super viewDidLoad];
    ViewController *vc=[[ViewController alloc]init];
    vc.leftViewControllerProtocol=self;
    [vc release];
}

-(void)updateTable
{
    arrayHistory=[self getHistory];
    [self.tableView reloadData];
}
