Xcode moving from view to view

I'm coding in Xcode, and i have a problem moving from view to view (xib to xib) My xib-files all have a personal .h and .m file.

this is the code i have:

The code to go from the first view to the quiz view in this case:

-(IBAction)switchviewMainToQuiz:(id)sender {

    ViewControllerQuiz *quizView = [[ViewControllerQuiz alloc] initWithNibName:nil bundle:nil];

    [self presentModalViewController:quizView animated:YES];

}

The code to go back from a view to my first view:

-(IBAction)switchviewQuizToMain:(id)sender {
    [self dismissModalViewControllerAnimated:YES];

}

the problem is that the second code just goes back and that gives sometimes an error or a fail in the app. So when i go to other views and then want to go back it often gets stuck. So does someone have an other code to switch the views, or maybe an other solution? Thank You!

I wouldn't create new viewController in IBAction. For me i would do this in this way:

1 Create property with viewController:

@property(nonatomic, strong) UIViewController *quizView ;

2 Synthesize it:

@synthesize quizView = _quizView;

3 Create method:

- (UIViewController *) quizView {
    if (_quizView == nil) {
        _quizView = [[ViewControllerQuiz alloc] initWithNibName:nil bundle:nil];
    }
    return _quizView;
}

4 In your IBAction:

-(IBAction)switchviewMainToQuiz:(id)sender {
    [self presentModalViewController:self.quizView animated:YES];
}
