を持っているのViewControllerを開くには、次のメッセージを毎回取得しておきますコレクションビューのセルのコードは次のとおりです

import UIKit 

class PhotoAlbumCollectionViewCell: UICollectionViewCell { 

@IBOutlet weak var imageView: UIImageView! 
func setThumbnailImage(thumbNailImage: UIImage) 
{ 
    self.imageView.image = thumbNailImage 
} 
} 

は???

Answer 1

this class is not key value coding-compliantは、あなたのIBActionリンクに問題があることを意味します。 Interface Builderで、cameraButtonClickedメソッドを呼び出すボタンを右クリックして、警告シンボルがあるかどうかを確認します。その場合は、リンクを削除してもう一度行います。

Answer 2

私はAnthonin C.の答えに同意します。そのIBOutlet接続の問題。あなたのxibまたはnibファイルに移動し、 "cameraButtonClicked"を接続するボタンの接続を削除すると、クラッシュの問題を解決します。
