Re: [MacRuby-devel] NSInvocationOperation usage Segmentation fault
Hi Alex, this works for me! 1. Alternativ framework 'Foundation' class Foo def bar puts "hallo" end end queue = NSOperationQueue.alloc.init #queue.addOperation operation queue.addOperationWithBlock ->{ Foo.new.bar } NSRunLoop.currentRunLoop.runUntilDate(NSDate.dateWithTimeIntervalSinceNow(2.0)) _____________________________________________________________________ 2. Alternativ class Foo < NSOperation def main p :hallo end end queue = NSOperationQueue.alloc.init operation = Foo.new queue.addOperation operation NSRunLoop.currentRunLoop.runUntilDate(NSDate.dateWithTimeIntervalSinceNow(2.0)) _____________________________________________________________________ 3. Alternativ framework 'Foundation' class Foo def bar p :hallo end end queue = NSOperationQueue.alloc.init operation = NSInvocationOperation.alloc.initWithTarget Foo.new, selector: :bar, object: nil queue.addOperation operation NSRunLoop.currentRunLoop.runUntilDate(NSDate.dateWithTimeIntervalSinceNow(2.0)) Mateus
The following code crashes with a segmentation fault. Any idea whether I misunderstood the usage or it is a macruby bug?
thanks, ALex.
---code------------------------------------------- framework 'Foundation'
class Foo def bar puts 'bar' end end
operation = NSInvocationOperation.alloc.initWithTarget Foo.new, selector: 'bar', object: nil
queue = NSOperationQueue.alloc.init queue.addOperation(operation)
# run the main loop for 2 seconds NSRunLoop.currentRunLoop.runUntilDate(NSDate.dateWithTimeIntervalSinceNow(2.0))
