Answer 1

Have you tried with adding imageView as subview of tabbar

var bgView: UIImageView = UIImageView(image: UIImage(named: "background.png"))
bgView.frame = CGRectMake(0, 420, 320, 60)//you might need to modify this frame to your tabbar frame
self.view.addSubview(bgView)

If we talk about height & width of tabbar ,it is 320*49 / 640*98 @2x for standard tabbar. so if you want to keep same dimension try with these width/height ratio.
