contactPicker 関数を使用して、連絡先から選択し、作成したテーブルビューに追加しています。ただし、アプリを実行して目的の連絡先をクリックすると、アプリがクラッシュします。問題は contactPicker(CNContactPickerViewController, didSelect...) 関数のようです。Swiftファイルを表示してもエラーは表示されません。誰かが問題を解決するのを助けることができますか?

delegateこのように宣言しますvar delegate: ViewTwo!が、それに値を割り当てることはありません。したがって、 を呼び出すdelegate.didFetchContacts([contacts])と、delegateisnilとアプリがクラッシュします。delegate = self(のどこかに追加したいようですviewDidLoad)。


viewDidLoadメソッドを正しく記述する必要があります。内部関数ではないことを確認するために移動します。

override func viewDidLoad() {}
