Comment on On Null Objects by Markus

Markus — Sun, 22 Jul 2012 09:42:48 +0000

Sure, you can design your API around YES == positive, but there are existing APIs that are not, e.g. NSView or the -compare: style methods.

I didn’t say it makes null-objects less viable than NSNull. I was merely arguing that you have to be careful how you use this pattern, as there might arise subtle issues if you pass an array with null-objects to some code which is not aware of it. It’s just deceptively easy to think “messaging to nil will always return failure so this is safe”.

Imagine a world where YES is used for positive results and NO is used for negative results. Then we’d design our API like this:

@property (nonatomic, assign, getter=isEnabled) BOOL enabled;
