为什么我的图片没有显示全屏？

Question

我有以下问题。我在视图控制器中有大约10个不同的图像。现在我希望图像在点击时切换到全屏。我已经将allow user interaction选项设置为yes，并输入我在本网站上找到的以下代码：

import UIKit

class ImageViewController: UIViewController {


    @IBAction func imageTapped(sender: UITapGestureRecognizer) {
        let imageView = sender.view as! UIImageView
        let newImageView = UIImageView(image: imageView.image)
        newImageView.frame = self.view.frame
        newImageView.backgroundColor = .blackColor()
        newImageView.contentMode = .ScaleAspectFit
        newImageView.userInteractionEnabled = true
        let tap = UITapGestureRecognizer(target: self, action: "dismissFullscreenImage:")
        newImageView.addGestureRecognizer(tap)
        self.view.addSubview(newImageView)
    }

    func dismissFullscreenImage(sender: UITapGestureRecognizer) {
        sender.view?.removeFromSuperview()
    }

有谁知道为什么我的图片无法点播并转为全屏？
