MGBox2什么都没有

Question

我想让MGBox在我的应用上工作，没有用 - 我看到的只是一个空白的应用窗口，我不确定我做错了什么（我甚至试图翻译目标c来自它附带的DemoController

这是我控制器的代码

import Foundation

class MainController: UIViewController {

    var appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
    @IBOutlet weak var mainView: MGScrollView!

    override func viewDidLoad() {
        super.viewDidLoad()
        mainView.contentLayoutMode = MGLayoutGridStyle
        mainView.bottomPadding = 8

        var box: MGBox = appDelegate.client.user.getViews()
        var tablesGrid = MGBox.boxWithSize(CGSize(width: 320,height: 0)) as! MGBox
        tablesGrid.contentLayoutMode = MGLayoutGridStyle
        mainView.boxes.addObject(tablesGrid)

        var table1 = MGBox.box() as! MGBox
        tablesGrid.boxes.addObject(table1)
        table1.sizingMode = MGResizingShrinkWrap

        var table2 = MGBox.box() as! MGBox
        tablesGrid.boxes.addObject(table2)
        table2.sizingMode = MGResizingShrinkWrap

        var menu = MGTableBoxStyled.box() as! MGTableBoxStyled
        table1.boxes.addObject(menu)

        var header = MGLine.lineWithLeft("MG Demo", right: nil, size: CGSize(width: 304, height: 44)) as! MGLine
        header.font = UIFont(name:"HelveticaNeue", size:18)
        header.leftPadding = 16
        header.rightPadding = 16
        menu.topLines.addObject(header)

    }
}
