Navigationを使用しView01、View02、View03と３枚のViewとボタンを並べて紐付けのアプリです。
View03からView01に戻る記述のみViewController03.mに記述しています。

#import "ViewController03.h"

@interface ViewController03 ()

@end

@implementation ViewController03

- (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.

}

- (void)didReceiveMemoryWarning

{

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}

/*

#pragma mark - Navigation

// In a storyboard-based application, you will often want to do a little preparation before navigation

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender

{

    // Get the new view controller using [segue destinationViewController].

    // Pass the selected object to the new view controller.

}

*/

// [back Root]戻るボタン

- (IBAction)backRoot:(id)sender {

    // ルートに戻る

    [self.navigationController popToRootViewControllerAnimated:YES];

}
