将视图添加到现有子视图

Question

I have a delegate which basically adds a view controller's view to this view's as a subview. The issue is that the background of the subview is always gray. I've set it so that the color is clear. Any idea why? I want it to be see through.

- (void)fullStryViewController:(FullStryViewController *)fullStoryVC addFullScreenSubView:(UIViewController *) viewController
{
    [self.view addSubview:viewController.view];
}

Answer 1

May be you can try this way ?,

- (void)fullStryViewController:(FullStryViewController *)fullStoryVC addFullScreenSubView:(UIViewController *) viewController
{
    viewController.view.backgroundColor = [UIColor clearColor];
    [self.view addSubview:viewController.view];
}
