Type Method

instancesRespond(to:)

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

Declaration

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

Parameters

aSelector

Return Value

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

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 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:).
