self.view.backgroundColor = [UIColor blueColor];

Answer 1

We've done exactly the same in our application. To hide the default TabBar, simply override the hidesBottomBarWhenPushed method in your parent view controller (or in every view controller in your App)

#pragma mark - Overriden UIViewController methods
- (BOOL)hidesBottomBarWhenPushed {
    return YES;
}

EDIT: This value can also be set from Storyboard:
