Instance Method インスタンスメソッド

methodForSelector:

Locates and returns the address of the receiver’s implementation of a method so it can be called as a function. あるメソッドのこのレシーバの持つ実装の所在（アドレス）を突き止めて返します、それでそれは関数として呼び出し可能です。

Declaration 宣言 

- (IMP)methodForSelector:(SEL)aSelector;

Parameters パラメータ

aSelector

A Selector that identifies the method for which to return the implementation address. The selector must be a valid and non-NULL. If in doubt, use the respondsToSelector: method to check before passing the selector to methodForSelector:.

Return Value 戻り値

The address of the receiver’s implementation of the aSelector.

Discussion 解説

If the receiver is an instance, aSelector should refer to an instance method; if the receiver is a class, it should refer to a class method.
