Swift多页面展示Tab切换Bug解决

今天遇到多页面展示，切换页面展示信息显示错乱。

解决方法：

移除上次添加的页面，再次添加就好了。

代码如下：

private func setupCustomerInfoPageView() {
        // 创建PageStyle，设置样式
        let style = PageStyle()
        style.isTitleViewScrollEnabled = true
        style.isTitleScaleEnabled = false
        style.titleViewBackgroundColor = UIColor.black
        style.titleViewHeight = 46
        style.titleSelectedColor = UIColor.customRedColor
        if models.count == 0 {
            let model = GuestInfoModel()
            model.levelName = "未登录"
            models = [model]
        }
        // 先移除
        for vc in self.children.reversed() {
            if vc != nil {
                vc.view.removeFromSuperview()
                vc.removeFromParent()
            }
        }
        for i in 0..<models.count {
            let controller = CustomerInfoController()
            controller.index = i
            controller.model = models[i]
            addChild(controller)
        }
        let pageView = PageView(frame: CGRect(x: 0, y: 0, width: kScaleWidth(534), height: kScaleHeight(390)), style: style, models: models, childViewControllers: children)
        view.addSubview(pageView)
    }
