Discussion 解説

During the evaluation of an NSWhoseSpecifier object that contains a test whose operator is NSEqualToComparison, an isEqualTo: message may be sent to each potentially specified object, if neither the potentially specified object nor the object being tested against implements a scriptingIsEqualTo: method.

The default implementation for this method provided by NSObject returns YES if an isEqualTo: message sent to the same object would return YES.
