@implementation NSNumber (Enumeration)
- (void)times:(void (^)(NSUInteger index, BOOL *stop))block
{
	NSInteger count = [self integerValue];
	if (count <= 0)
	    return;

	BOOL stop = NO;
	for (NSUInteger index = 0; index < count; index++) {
		block(index, &stop);
		if (stop) break;
	}
}
@end

A couple of improvements made here.

• There was no accounting for the NSNumber to be negative, which would mean it would infinitely iterate.
• This also removes the need to call integerValue on every iteration.

Heh. Appreciate the safety check/cleanup of my little throw-away method. Yay open source!
