Thanks Laurent, I'd forgotten about performRubySelector:. The ruby class I'm using takes 2 args, one of them a default argument, so I created an initWith method to work around that - problem solved now. Alan On 17 Jan 2011, at 21:51, Laurent Sansonetti wrote:
Hi Alan,
When performing Ruby selectors on Ruby objects from Objective-C, the performRubySelector: method should be used instead of performSelector:, because it takes care of special Ruby semantics such as splat or default arguments.
[RubyClass performRubySelector:@selector(new:) withArguments: arg, NULL];

Hi, Is there any way to inform an Objective-C class of the existence of a ruby class so that instances can be created in Objective-C code? Currently I am doing the following:
[[MacRuby sharedRuntime] evaluateString:[NSString stringWithFormat:@"RubyClass.new('%@')", arg]];
If I'm adding quite a few objects (300+) to an array in a loop, this line of code is quite slow. My assumption (which may be false) is that either of the 3 options below would be quicker.
[RubyClass performSelector:@selector(new:) withObject:arg]; [RubyClass new:arg]; [[RubyClass alloc] initWithArg:arg];
Are any of those options (or an equivalent) a possibility?
