The RubyMotion Way

&#62; <i>Rubyists get a lot of flak for the kind of DSLs and black magic method_missing tricks the above libraries use; but you know what, maybe that attitude is just what Objective-C has been missing.</i><p>I politely disagree. Objective-C hasn't been missing risky and error-prone approaches that merely attempt to save a few characters at the cost of correctness. Extensions like 'when' are vague, and could just as easily be co-opted for KVO as they could for UIControl event handling.<p>Also, the example is not accurate. In Objective-C, you'd control-drag from the button to your action method, using Interface Builder.

" If you've tried projects in Ruby and just didn't like it, RubyMotion probably won't change your mind. But if you've ever wanted to make iOS or Mac apps but didn't want to get over the hump that is Objective-C, maybe this will get you going."<p>Can RubyMotion itself be used to create Mac apps in addition to iOS apps?

I sometimes wish rubymotion and macruby had named parameter with default value, something like<p>def functions(with, this: syntax="default value") end<p>but over all, I think rubmyotion rocks and I hope and brings some great Objective-c/Cocoa world into ruby-world and vice-versa.

If you want a deeper dive into RubyMotion, the creator was just on The Changelog podcast - <a href="http://thechangelog.com/post/25928209107/episode-0-8-2-ruby-motion-macruby-and-more-with-laurent" rel="nofollow">http://thechangelog.com/post/25928209107/episode-0-8-2-ruby-...</a><p>He actually left Apple to launch RubyMotion -- a commercial product, by the way -- after creating MacRuby and developing/maintaining it for several years.

iOS development is not only objective-c and Cocoa Touch. XCode, interface builder, instruments are also big helpers and sometimes there can be memory problems that you can only trace with instrument.

Why the tricky horizontal scrolling on this page? (In Chrome and Firefox, at least. Oddly, Safari presents it as a regular vertical page..)

Are there examples of products that were developed with RubyMotion?

&#62; (after the code preview) Pretty nice right?<p>Yes, very nice. And also very annoying.<p>Using these little shortcuts everywhere is confusing. There is no order in things.<p>ObjC is beautiful. There are classes, instances, methods, blocks. And everything has its place.<p>This is a mess, Rails is a mess, most of Ruby code is a mess.<p>Proceed with the downvotes.
