segmented control - unrecognized selector sent to instance - ios

Question

I want to use sender to get the value from segmented control, but I am getting the unrecognized selector sent to instance error. The segmented control was added within a view. I've tried removing the semicolon and/or sender and none of the prior posts I've found seem to help. Any ideas?
Swift Code
var segCntrl = UISegmentedControl(items: ["Yes","No"])
segCntrl.tag = 100
segCntrl.center = CGPointMake(qView.bounds.width/2, qView.bounds.minY+40)
self.qView.addSubview(segCntrl)
func segmentorSwitch(sender: AnyObject) {
if(sender.selectedSegmentIndex == 1) {
println("Yes selected")
}
else if(sender.selectedSegmentIndex == 2) {
println("No selected")
}
}
segCntrl.addTarget(self, action: "segmentorSwitch:", forControlEvents: UIControlEvents.ValueChanged)
Error code:

Answer 1

Looks like segmentorSwitch: is implemented inside another method. Define it outside the method in which your code is contained, and this should be fixed.
