Try to embed navigation controller in storyboard as below :

First select your testView1 in storyboard .

Select Navigation Controller

And Changes as below

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.

   /// testView2 *detail = [testView2 new];
    testView2 *detail =  [self.storyboard instantiateViewControllerWithIdentifier:@"testView2 Identifier"]; // if you have add controller in storyboard
    [self.navigationController pushViewController:detail animated:YES];
}
