プログラミング雑記: 画面遷移・表示にかかわるDelegateたち

デリゲートの厄介なのは元クラスのリファレンスにはメソッドの一覧がなく、デリゲートのリファレンスを開かないとわからないことです。加えて画面遷移・表示にかかわるオブジェクトの多くにデリゲートがあるため、行いたいことによって元オブジェクトが変わってきます。そこで、画面遷移・表示にかかわるオブジェクトをまとめてみました。

UIWebView、UITextViewを使う場合はそのデリゲートが加わります。

UIWebViewDelegate
UITextViewDelegate

UIActionSheetを使う場合はそのデリゲートが加わります。

UIActionSheetDelegate

UITextFieldを使う場合は編集、キーボード操作のためにそのデリゲートが加わります。

UITextFieldDelegate

デリゲートではありませんが、プログラムでインスタンスを作る、あるいはサブクラスを作りカスタマイズすることがあるクラスです。

全部を網羅していませんが、主だったメソッドが呼ばれる順序です。

UIViewController +initialize (クラスイニシャライザー）
UIWebView -initWithCoder (Stroryboardからインスタンスを作成した場合）
UIViewContoller -loadView
UIViewContoller -viewDidLoad
UIWebView -loadData
UIViewContoller -viewWillAppear
UIViewContoller -shouldAutorotateToInterfaceOrientation
UIViewContoller -viewWillLayoutSubviews
UIViewContoller -viewDidLayoutSubviews
UIViewContoller -viewDidAppear
UIWebView -webViewDidFinishLoad
UIViewContoller -viewWillLayoutSubviews
UIViewContoller -viewDidLayoutSubviews

・　DOT.NETのデリゲートとの比較を追加しました。
