I found a prefect solution, you only need to subclass UITabBar and then do the following actions to clean that annoying views

class MainTabBar: UITabBar {
    var cleanDone = false

    override func layoutSubviews() {
        super.layoutSubviews()
        self.deleteUnusedViews()
    }

    func deleteUnusedViews() {
        if !self.cleanDone {
            var removeCount = 0
            for (_, eachView) in (self.subviews.enumerate()) {
                if NSStringFromClass(eachView.classForCoder).rangeOfString("_UITabBarBackgroundView") != nil {
                    eachView.removeFromSuperview()
                    removeCount += 1
                }
                if NSStringFromClass(eachView.classForCoder).rangeOfString("UIImageView") != nil {
                    eachView.removeFromSuperview()
                    removeCount += 1
                }
                if removeCount == 2 {
                    self.cleanDone = true
                    break
                }
            }
        }
    }
}
