XLPagerTabStrip之间的空格

Question

我正在尝试在我的应用程序中实现XLPagerTabStrip。一切都很好，因为我遵循了官方的Tutorial，我已经把我的collectionView的颜色改成了红色。当应用程序在模拟器中运行时，我看到有一个类似图像的空白区域

我想知道怎样去掉那个空格？因为它应该是红色的，我怎么才能改变黑线的颜色呢？

这是我的代码：

override func viewDidLoad() {
    super.viewDidLoad()
    settings.style.buttonBarBackgroundColor = .red
    settings.style.buttonBarItemBackgroundColor = .red
    settings.style.selectedBarBackgroundColor = purpleInspireColor
    settings.style.buttonBarItemFont = UIFont.systemFont(ofSize: 12, weight: UIFont.Weight.regular)
    settings.style.selectedBarHeight = 0.5
    settings.style.buttonBarMinimumLineSpacing = 0
    settings.style.buttonBarItemTitleColor = .white
    settings.style.buttonBarItemsShouldFillAvailiableWidth = true
    settings.style.buttonBarLeftContentInset = 0
    settings.style.buttonBarRightContentInset = 0
    changeCurrentIndexProgressive = { [weak self] (oldCell: ButtonBarViewCell?, newCell: ButtonBarViewCell?, progressPercentage: CGFloat, changeCurrentIndex: Bool, animated: Bool) -> Void in
        guard changeCurrentIndex == true else { return }
        oldCell?.label.textColor = .white
        newCell?.label.textColor = self?.purpleInspireColor
    }
}

我解决了我的问题，我忘记了这一行super.viewDidLoad()最后应该是viewDidload方法
