Сбой UIView при отправке IBAction

Question

Я недавно начал настраивать свое приложение, используя архитектуру MVC. У меня есть класс GetStartedView с соответствующим файлом XIB, как показано ниже. У меня также есть GetStartedViewController, который загружает представление. У меня проблема в том, что всякий раз, когда я нажимаю кнопку, приложение вылетает. У меня есть представление о том, что происходит, но я совершенно заблудился, как это исправить. Я неправильно загружаю перо? Любые предложения и помощь с благодарностью.

#import "GetStartedView.h"

@implementation GetStartedView

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:@"GetStartedView" owner:self options:nil];
        // assuming the view is the only top-level object in the nib file (besides File's Owner and First Responder)

        UIView *nibView = [nibObjects objectAtIndex:0];
        [self addSubview:nibView];
    }
    return self;
}

/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.

{
    // Drawing code
}
*/

- (IBAction)signupButtonTouched:(id)sender {
    NSLog(@"hello");
}

- (IBAction)signinButtonTouched:(id)sender {
}

- (IBAction)facebookButtonTouched:(id)sender {
}

- (IBAction)twitterButtonTouched:(id)sender {
}
@end


@interface GetStartedViewController ()

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

- (void)viewDidLoad
{
    [super viewDidLoad];

    GetStartedView *gsView = [[GetStartedView alloc] initWithFrame:self.view.frame];
    [self.view addSubview:gsView];

    //[self.view bringSubviewToFront:nibView];
}
