feature request: nsstring isEmpty

[mgerlach-klick]

Would you consider adding an [NSString isEmpty] as described here: http://stackoverflow.com/a/899320 ?

I think, that isEmpty written this way is more like a method for something more general like NSObject. It is too expensive for NSString exclusively, isn't it?

[stanislaw]

Also, if we do know that thing responds to length and count - then why those casts to NSData and NSArray respectively?

[mgerlach-klick]

That's true, I was mainly thinking of using it for nsstring, but this is really something for NSObject. Perhaps with the added [NSNull null] check mentioned in the comments?

BTW since I have you here: I love your library, thanks for your work!

We can adopt something like Brent Simmon's emptiness functions http://inessential.com/2012/07/28/emptiness
