Here is a paste from my program where I successfully set up and use a timer.
Looks like I used a slightly different method from the same API. Hope it helps:
class LevelView < NSView
attr_accessor :keyboard_view
def initWithFrame frame
$game = Game.new(self)
super(frame)
@timer = NSTimer.scheduledTimerWithTimeInterval 1.0/FPS,
target:self,
selector:'doTick:',
userInfo:nil,
repeats:true
NSRunLoop.currentRunLoop.addTimer @timer, forMode:NSModalPanelRunLoopMode
NSRunLoop.currentRunLoop.addTimer @timer, forMode:NSEventTrackingRunLoopMode
