Instance Method インスタンスメソッド

isProxy

Returns a Boolean value that indicates whether the receiver does not descend from NSObject.

Declaration 宣言

- (BOOL)isProxy;

Return Value 戻り値

NO if the receiver really descends from NSObject, otherwise YES.

Discussion 解説

This method is necessary because sending isKindOfClass: or isMemberOfClass: to an NSProxy object will test the object the proxy stands in for, not the proxy itself. Use this method to test if the receiver is a proxy (or a member of some other root class).
