I'm not sure if this is what you're looking for, but Objective-C 2.0 has
this:
NSArray *a = [NSArray arrayWithObjects:@"Hello",@"Goodbye",nil];
for (NSString *s in a) {
if ([s isEqualToString:@"Goodbye"]) {
NSLog(@"it is equal");
}
}
And you can have an additional int (or NSInteger) counter to keep track of
which object it is.
Oh, you could also do [NSArray indexOfObject:]. if it returns NSNotFound,
it's not in the array.
