ViewController initialized but nothing inside

Question

I'm missing an obvious point on my code but I'm not able to see where.

TermsViewController *termsVC = [[TermsViewController alloc] init];
termsVC.signUpVC = self;
[self presentViewController:termsVC animated:YES completion:nil];

When the method presentViewController is called, I can see that the method viewDidLoad is called on my TermsViewController but there is nothing execpt a black screen.

When I had termsVC.view.backgroundColor = [UIColor greenColor]; I can see a green screen. When I looked deeply with the debugger, I can see that my controller is initialized but my components (UITextField + UIButton) are nil. I thought that the presentViewController was loaded the view linked to the controller but finally not.

Here is my TermsViewController:

#import "TermsViewController.h"

@interface TermsViewController ()

@end

@implementation TermsViewController
@synthesize signUpVC;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.title = [[NSString alloc] initWithFormat:@"Test"];
    acceptButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];

    // Do any additional setup after loading the view.
}

You need to load your view controller from the storyboard, try this:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"<YourStoryboardFileName>" 
                                                     bundle:nil];
TermsViewController *termsVC = [storyboard instantiateViewControllerWithIdentifier:@"<TermsViewController Storyboard ID>"];
termsVC.signUpVC = self;
[self presentViewController:termsVC animated:YES completion:nil];
