ViewController에 뷰가 표시되지 않습니다.

Question

부모 인 "GameViewCController"로부터 상속받은 "TapRaceViewController"라는 ViewController가 있습니다. 그러나 TapRaceViewControllers 하위보기 중 하나도 표시되지 않습니다. GameController의보기 만 표시됩니다. 왜 그런가요? TapRacerViewController의 viewDidLoad에 호출되고, 그래서 파단이 추가되지 않는 이유는 표시되지 않습니다.

@implementation TapRacerViewController 
{ 
    //A single tap on the screen 
    UITapGestureRecognizer* singleTap; 

    //the player 
    UILabel* player; 

    //The view 
    UIView* m_baseView; 
} 

- (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. 

    //Create the base view 
    m_baseView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)]; 
    [m_baseView setBackgroundColor:[UIColor blueColor]]; 
    [self.view addSubview:m_baseView]; 

    //Create the tap gesture 
    singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap)];

    //Create the player 
    player = [[UILabel alloc] initWithFrame:CGRectMake(self.view.bounds.size.width - 50, self.view.bounds.size.height/2, 50, 50)]; 
    [player setBackgroundColor:[UIColor blackColor]];

}

보기를 추가하지 않은 것 같습니다.

[self.view addSubview:m_baseView]; 

viewDidLoad 메서드의 끝에이 행을 씁니다.
