After the Ruby code that defines the class has been evaled, you should be able to do the following: Class rubyClass = NSClassFromString(@"RubyClass"); id rubyObject = [[rubyClass alloc] init]; On Jan 17, 2011, at 2:05 PM, Alan Skipp wrote:
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?
