[Rubycocoa-talk] Problem overriding instance methods.

[Eloy D. <elo...@gm...>]

Hello all,

I have a problem where I try to override an instance method of a class
which comes from a framework that I have generated the bridgesupport
for as per instructions on the wiki...

The code is like this:

==============================================================
require 'osx/cocoa'

OSX.require_framework
File.expand_path('../../vendor/HDCrashReporter.framework', __FILE__)

class OSX::HDCrashReporter
  def sendReport(sender)
    puts "Where's the message to this method dude?!"
  end

  def self.doCrashSubmitting
    puts 'HDCrashReporter class method. This works...'
  end
end

class OSX::NSString
  def capitalizedString
    puts 'NSString instance method. This does work...'
  end
end

OSX::HDCrashReporter.doCrashSubmitting # prints: HDCrashReporter class
method. This works...
"foo".to_nsstring.capitalizedString    # prints: NSString instance
method. This does work...

OSX::HDCrashReporter.alloc.init.sendReport(nil)
==============================================================


The last call only works if I initialize an instance myself, so if I
call it from the ruby side.
But it doesn't when the method is called as from the interface, at
that point it simply uses the original method.

The original method is as follows:

- (IBAction) sendReport: (id) sender
{
  // code
}

I have included the output with $RUBYCOCOA_DEBUG = true
I hope this is helpful...

Cheers,
Eloy
