无法使用推送 segue 在视图控制器之间传递 UIImageView

Question

我正在尝试使用 Push Segue 将 UIImageView 从主视图控制器传递到详细视图控制器。 Master View Controller 上的所有内容都可以正常加载，我已经使用 Master View Controller 上的 UIImageView 创建了一个 push segue。这是我的主视图控制器 -

class TrackMasterViewController: UIViewController {

    @IBOutlet weak var artistName: UILabel!

    @IBOutlet weak var albumName: UILabel!

    @IBOutlet weak var numberOfTracks: UILabel!

    @IBOutlet weak var coverImage: UIImageView!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        let firstRandomNumber = calculateRandomNumber()

        artistName.text = Track(index: firstRandomNumber).artist
        albumName.text = Track(index: firstRandomNumber).album
        coverImage.image = Track(index: firstRandomNumber).image
        numberOfTracks.text = Track(index: firstRandomNumber).track

    }

传递的是封面图。这是我的 segue 函数 -

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "trackSegue" {
            let playlistDetailController = segue.destinationViewController as? TrackDetailViewController
            playlistDetailController?.image = UIImage(named: coverImage)

        }
    }

在我的详细视图控制器中，我有以下内容：

class TrackDetailViewController: UIViewController {

    @IBOutlet weak var albumCover: UIImageView!

    var image:UIImage? = nil

    override func viewDidLoad() {
        super.viewDidLoad()

        albumCover.image = image

        // Do any additional setup after loading the view.



    }

}

如果能帮助确定问题所在，我们将不胜感激。

尝试在 prepareForSegue: 内部进行更改，而不是使用：

playlistDetailController?.image = UIImage(named: coverImage)

使用：

playlistDetailController.image = coverImage.image

祝你好运！
