Instance Method

arrayByApplyingSelector:

Returns an array containing the results of sending the specified message to each object in the receiver.

Declaration

- (NSArray<id> *)arrayByApplyingSelector:(SEL)selector;

Parameters

selector

A selector identifying the message to be sent to each object in the array.

Return Value

A new array containing the results of sending the selector message to each object in the receiver, starting with the first object and continuing through the element array to the last object.

Discussion

The method identified by selector must not take any arguments and must return an Objective-C object. It should not have the side effect of modifying the receiving array. The order of the items in the result array corresponds to the order of the items in the original array.
