How to run code snippets in Objective-C

Question

While trying to learn Objective C from a book, I'd like to be able to run some code snippets like...

NSString *str = @"Hello, world!";
NSLog(@"Retain count is %d", [str retainCount]);

In Ruby I'd just put this in an snippet.rb file and run ruby snippet.rb from the terminal. JavaScript has jsfiddle.net. Is there an equally easy way to do this with objective c?

@BrainLikeADullPencil See this question on why using `-retainCount` is a bad idea: http://stackoverflow.com/questions/4636146/when-to-use-retaincount — Kitsune, Jan 02 '13 at 22:49
@bryanjclark No, this one is about running snippets, the other one about integration in Xcode. — Nikolai Ruhe, Jan 02 '13 at 22:51
@Kitsune thanks, I'm just getting an overview of the environment now. However, I thought memory management was now taken care of by ARC so I wouldn't even have to think about it once I got into more of the nitty gritty — BrainLikeADullPencil, Jan 02 '13 at 22:56
@jrturton feel free to recommend something better for the latest ios release. However, since I've got this already and just looking for an overview now, I'll finish it til I find something better. — BrainLikeADullPencil, Jan 03 '13 at 02:15

If you're on a Mac there's the handy CodeRunner. It's $9.99 on the App Store but to me it was worth every penny.

is this just an ordinary code editor? looks like it to me...should I maybe see if there's an extension for my current editor (Sublime), or is there something more to CodeRunner that I should be aware of... – BrainLikeADullPencil Jan 02 '13 at 22:43
Code Runner let's you type a short snippet in a language of your choice and compiles, links and runs it. It prints the console output and lets you type input to stdin. – Nikolai Ruhe Jan 02 '13 at 22:45
+1 coderunner is great. Before that I had dummy Xcode projects and unit tests all over the place. – jrturton Jan 02 '13 at 22:52
has anyone used it on Mountain Lion? – BrainLikeADullPencil Jan 02 '13 at 23:03
@NikolaiRuhe saw a bad review about it by someone using Mountain Lion – BrainLikeADullPencil Jan 02 '13 at 23:23
@NikolaRuhe is there documentation anywhere? it's opening my whole Macintosh hardrive in the editor. How do I just open one folder – BrainLikeADullPencil Jan 02 '13 at 23:36
