Cocoa NSArray/NSSet: -makeObjectsPerformSelector: vs. fast enumeration

Question

I want to perform the same action over several objects stored in a NSSet.

My first attempt was using a fast enumeration:

for (id item in myS         


        

Answer 1

I would not use makeObjectsPerformSelector for the simple reason that it is the kind of call that you don't see all that often. Here is why for example - I need to add debugging code as the array is enumerated, and you really can't do that with makeObjectsPerformSelector unless you change how the code works in Release mode which is a real no no.

for (id item in mySetOfObjects)
{
    #if MY_DEBUG_BUILD
    if ([item isAllMessedUp])
        NSLog(@"we found that wily bug that has been haunting us"); 
    #endif

    [item action];
}
