一、方法方式处理

@IBAction func btn1(_ sender: UIButton) {
        let vc =  customedPageController()
        vc.hidesBottomBarWhenPushed = true;
        self.navigationItem.backBarButtonItem = UIBarButtonItem.init()
        self.navigationController?.pushViewController(vc,animated: true

    }

    // MARK: - An example of `PageController`
    fileprivate func customedPageController() -> WMPageController {
        let vcClasses:[AnyClass] = [AllOrderVC().classForCoder,WaitPaymentOrderVC().classForCoder,WaitDeliveryOrderVC().classForCoder,WaitReceiveOrderVC().classForCoder,WaitEvaluateVC().classForCoder]
        let titles = ["全部订单","待付款","待发货","待收货","待评价"]
        let pageVC = WMPageController(viewControllerClasses: vcClasses,andTheirTitles: titles)
//        pageVC.tabBarController?.tabBar.isHidden = true
        pageVC.title="我的订单"
        pageVC.itemsWidths = [70,50,50]   //每个 MenuItem 的宽度‘
        pageVC.menuView?.frame = CGRect.init(x: 0,y: 0,width: DeviceMaxWidth,height: 44)    //导航栏高度
        pageVC.menuView?.backgroundColor = UIColor.red    //导航栏颜色
        pageVC.postNotification = true  //
        pageVC.bounces = true
        pageVC.titleSizeSelected=13    //选中时的标题尺寸
        pageVC.titleSizeNormal=14      //非选中时的标题尺寸
        pageVC.menuViewStyle = .line    //Menu view 的样式，默认为无下划线
        pageVC.titleColorSelected=UIColor.red    //标题选中时的颜色,颜色是可动画的.
        pageVC.titleColorNormal=UIColor.black    //标题非选择时的颜色,颜色是可动画的
        pageVC.scrollView?.height = 100

        return pageVC
    }
