我的UIScrollView不会向下滚动.我不知道为什么.我已经关注了有关此问题的Apple文档.

@IBOutlet weak var scroller: UIScrollView!

    override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.

}

override func viewDidLayoutSubviews() {
    scroller.scrollEnabled = true
    // Do any additional setup after loading the view
    scroller.contentSize = CGSizeMake(400, 2300)
}

请指教.谢谢.
