Type Method


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


class func instancesRespond(to aSelector: Selector!) -> Bool



Return Value

true if instances of the receiver are capable of responding to aSelector messages, otherwise false.


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 false.

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 responds(to:).
