Answer 1

removeObjectIdenticalTo:

Removes all occurrences of a given object in the array.

Discussion This method uses the indexOfObjectIdenticalTo: method to locate matches and then removes them by using removeObjectAtIndex:. Thus, matches are determined using object addresses. If the array does not contain anObject, the method has no effect (although it does incur the overhead of searching the contents).
