Adding a custom subview (created in a xib) to a view controller's view - What am I doing wrong

I've created a view in a xib (with an activity indicator, a progress view and a label). Then I've created .h/.m files:

#import <UIKit/UIKit.h>

@interface MyCustomView : UIView {
    IBOutlet UIActivityIndicatorView *actIndicator;
    IBOutlet UIProgressView *progressBar;
    IBOutlet UILabel *statusMsg;
}

@end

#import "MyCustomView.h"

@implementation MyCustomView    

- (id)initWithFrame:(CGRect)frame {
    if ((self = [super initWithFrame:frame])) {
        // Initialization code
    }
    return self;
}

- (void)dealloc {
    [super dealloc];
}

@end

In IB, I set the file's owner and view identity to MyCustomView and connect the IBOutlet to the File's owner

In MyViewController.m, I've:

- (void)viewDidLoad {

    [super viewDidLoad];   

    UIView *subView = [[MyCustomView alloc] initWithFrame:myTableView.frame];
    [subView setBackgroundColor:[UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.5]];

    [myTableView addSubview:subView];
    [subView release];
}

When I run the app, the view is added, but I can't see the label, the progress bar and the activity indicator.

What am I doing wrong?
