------------------------------------+---------------------------------------
Reporter: rebo...@… | Owner: lsansone...@…
Type: defect | Status: new
Priority: blocker | Milestone:
Component: MacRuby | Keywords: NSOperation NSOperationQueue
------------------------------------+---------------------------------------
The below fails wtih a segmentation fault, not sure if it is because I am
calling in the wrong way
{{{
## Macruby test of NSOperation and NSOperationQueue
class PageLoadOp < NSOperation
def initialize
return self
end
def main
puts 'test'
end
end
## in awakeFromNib or whever
queue = NSOperationQueue.alloc.init
foobar = PageLoadOp.new
queue.addOperation(foobar)
sleep(10)
}}}
not sure if the below helps::
