nib2objc
以下のように、パラメータにXIBファイルを指定すると、標準出力にコードが出力されます。
$ nib2objc WebView.xib > WebView.m
このようなビューから下記のコードが出力されます。
XIBファイルをソースコードに変換する場合というのは、パフォーマンスのために、XIBファイルを使わないようにしたい場合がほとんどだと思うので、このコードをもってXIBファイルを置き換えるのは難しいです。
インスタンス変数やアクションの接続が無くなってしまうので、それらを再構築する手間を考えると、自分で書いた方が早いと思います。
ただ、ソースコードが公開されているので、工夫して改良すれば、便利なツールになりそうです。
