クラスの Private なメソッド、プロパティ、インスタンス変数を調べるには Objective-C の Runtime API を使う。
メソッドは Method, プロパティは objc_property_t, インスタンス変数は Ivar 型で取得できる。
#import <objc/runtime.h>
で Runtime API を import してそれぞれ以下のように実装する。
これを使って例えば NSObject について調べる場合、以下のようにする。
Class cls = [NSObject class];
PrintMethodList(cls);
PrintPropertyList(cls);
PrintIvarList(cls);
出力結果は以下
ちょっとメソッドのリストが長いのでメソッド一覧は最後に記載。
見てみると Private なものでもアンダーバーが付いてないものもあれば、アンダーバーが3つも付いているものもあったりする。
他には CA_ みたいに Prefix+アンダーバー形式のものもあったりしておもしろい。
