Type Method

instancesRespondToSelector:

Returns a Boolean value that indicates whether instances of the receiver are capable of responding to a given selector.

Declaration

+ (BOOL)instancesRespondToSelector:(SEL)aSelector;

Parameters

aSelector

Return Value

YES if instances of the receiver are capable of responding to aSelector messages, otherwise NO.

Discussion

If aSelector messages are forwarded to other objects, instances of the class are able to receive those messages without error even though this method returns NO.

To ask the class whether it, rather than its instances, can respond to a particular message, send to the class instead the NSObject protocol instance method respondsToSelector:.
