[MacRuby-devel] calling Objective-C method with block parameter

[Eloy Duran]

Ah yes, this is one for a FAQ. Linking against a framework does not automatically make MacRuby read the BridgeSupport files that might be there. But if you use the MacRuby Kernel::framework method, it will do both. (Though it’s not necessary to do it from rb_main.rb, just before the code where you will use the framework.)

Therefore I assumed that by linking to the framework, macruby automatically loads it because I am able to create objects from the framework's header file. The failure only occurs when attempting to call methods that require a bridgesupport file.

I've tried making a clean build to no avail and I've checked the built app package and the framework is copied and the bridgesupport file is present. I also created a new test project in Xcode (just in case something had went awry with the other project) and I had to explicitly call 'load_bridge_support_file' to get the framework working there also.

I finally got it working after invoking, 'load_bridge_support_file' in my controller class. Is there something I should be doing that would enable macruby to automatically detect and load the bridgesupport file included in my framework?
