Question

我正在创建一个集合视图。我以编程方式设置CollectionViewController并创建customCell文件。我在故事板中设计了单元格。我以前做过这个，它完美地运作了。但由于某种原因，我不断收到此错误。我的CustomCell类在故事板中连接。标识符与collectionviewcontroller方法中指定的标识符完全相同。我已经清理，退出并重新启动了xcode。我甚至试图用另一个我熟悉的单元接口来运行collectionviewcontroller。无论我做什么，我都会遇到这个标识符问题。这是一些代码

import Foundation

import UIKit

import Alamofire

class CommentsCollectionViewController: UICollectionViewController, UICollectionViewDelegateFlowLayout {
    override func viewDidLoad() {
        super.viewDidLoad()

        self.collectionView?.backgroundColor = UIColor(white: 0.85, alpha: 1)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    override func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return 1
    }

    override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
        let cellIdentifier = "CommentsCollectionViewCell"
        let cell = collectionView.dequeueReusableCellWithReuseIdentifier(cellIdentifier, forIndexPath: indexPath) as! CommentsCollectionViewCell

        return cell
    }

}

这是我的CollectionViewCell：

import Foundation
import UIKit
import Cosmos

class CommentsCollectionViewCell: UICollectionViewCell {

    @IBOutlet weak var profileImageView: UIImageView!
    @IBOutlet weak var usernameLabel: UILabel!
    @IBOutlet weak var userRatingView: CosmosView!
    @IBOutlet weak var compatibilityLabel: UILabel!
    @IBOutlet weak var commentLabel: UILabel!

    override func awakeFromNib() {
        super.awakeFromNib()
    }
}

还有什么我可以做的才能使这项工作？

我想出了这个问题。这是我实例化视图控制器的方式。我必须这样呈现：

    let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
    let commentsView = storyBoard.instantiateViewControllerWithIdentifier("seeComments")

    self.presentViewController(commentsView, animated: true, completion: nil)

其中“seeComments”是故事板中的CollectionViewController。
