私はObjective-CとiOSプログラミングを「IOSプログラミング:The Big Nerd Ranchガイド(第2版)」で教えているので、チュートリアルで接続を作成したいという問題が発生しましたApp Delegateオブジェクトには、このオブジェクトは私のためのInterface builderのObjectsリストには表示されません。私は、その本のバージョンがXcode(4.2)の少し後ろにあるかのように、タイプミスかバージョンが異なると確信しています。私は、MOCAppDelegateオブジェクトがIBに表示されるべきものであることはかなり確信していますが、私はそれを実現するために必要なコードの変更を知るにはまだよく分かりません。以下のようにして、チュートリアルのグラフィックの指示どおりに接続を実行できるように、IBのオブジェクトリストにオブジェクトが表示されます。Xcode Interface Builderアプリケーションデリゲートオブジェクトが表示されない
注:私は研究し、この発見:Having trouble hooking up instance variables to AppDelegateをしかし、この解決策は私のために動作しませんでした(または私はそれを正しく実装されていませんでした)
