UIView change background color to image

I managed to successfully change some of my UIView background to a custom image using self.view.backgroundColor = 开发者_如何学JAVA[UIColor colorWithPatternImage:[UIImage imageNamed:@"myCustomBackground.jpg"]];

But it does not work on a particular view in a controller that is presented modally as such,

LoginViewController *loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:[NSBundle mainBundle]];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:loginViewController];    
navController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
navController.navigationBar.barStyle = UIBarStyleBlack;
[self presentModalViewController:navController animated:NO];
[loginViewController release];
[navController release];

It seems like self.view inside this controller is behind the view it was showing.

EDIT

LoginViewController.m

- (void)viewDidLoad {
    self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"myCustomBackground.jpg"]];
}

self.view in this case seems to be hidden behind the current view that it's displaying. I did not add any subView beforehand.

As you mentioned in your comments, your view contains UIScrollView, UILabel and UIButton.

You should set to all this subviews property backgroundColor = [UIColor clearColor];. Hopefully that would help.

If you are editing subview in IB then you should find property Background in Attributes Inspector and select Clear Color (for all subviews).
