Objective C Empty Array in Different Class - objective-c

Question

Question with trying to simply clear a mutablearray in another class in objective C
the code all runs fine, just the data doesnt get wiped....
SecondViewController.h
#interface SecondViewController : UIViewController <UITableViewDelegate,UITextFieldDelegate,ABPeoplePickerNavigationControllerDelegate>
{
AppDelegate *appDelegate;
}
#property (nonatomic, retain) NSMutableArray *contactsArray;
Thats the declaration of the mutablearray...
then from the class that i am trying to delete it.
listViewController.h
#import "SecondViewController.h"
#interface ListViewController : UIViewController <UITableViewDelegate,ABPeoplePickerNavigationControllerDelegate,UITabBarControllerDelegate>{
AppDelegate *appDelegate;
SecondViewController *secondViewControl;
}
#property (nonatomic, retain) IBOutlet UITableView *table;
then in the main file i use the code
[secondViewControl.contactsArray removeAllObjects];
but then when i check the array it has not been emptied...
EDIT:
#implementation ListViewController
#synthesize table;
/*- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}*/
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
appDelegate = (AppDelegate *)[[UIApplication sharedApplication]delegate];
secondViewControl = [[SecondViewController alloc]init];
