Buton ile son viewcontroller sayfasından rootviewcontroller sayfasına dönüş yapmak istiyorum.Burada NSArray ı nasıl kullanmalıyım

Teşekkürler.

[code]

    NSString *starttEkle=[[NSBundle mainBundle] pathForResource:@"startt" ofType:@"png"];

    UIImage *starttEkle1=[[UIImage alloc] initWithContentsOfFile:starttEkle];

    UIButton *starttButton=[UIButton buttonWithType:UIButtonTypeCustom];

    starttButton.frame=CGRectMake(100, 300, 120, 50);

    [starttButton setImage:starttEkle1 forState:UIControlStateNormal];

    [starttButton addTarget:self action:@selector(starttButton) forControlEvents:UIControlEventTouchUpInside];

    [self .view addSubview:starttButton];    

    self.view.backgroundColor=[UIColor colorWithRed:1.000 green:0.584 blue:0.000 alpha:1.000];

    [super viewDidLoad];

}

-(IBAction)UIButton:starttButton;

{

    UINavigationController *animalend=self.navigationController;

    [animalend popToRootViewControllerAnimated:NO];

    [animalend pushViewController:animalend animated:YES];

    /*

    animal20ViewController *aniView20=[[animal20ViewController alloc]init];

    NSMutableArray *animal=[NSArray arrayWithArray:self.navigationController.modalViewController];

    [animal insertObject:aniView20 atIndex:[animal count]-19];

    [self.navigationController setViewControllers:animal animated:NO];

    [self.navigationController popViewControllerAnimated:YES];

    */

   // mainpageViewController *animal=[[mainpageViewController alloc] initWithNibName:@"mainpageViewController" bundle:Nil];

  //[self.navigationController pop];

}
