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))
