Yup, still getting them, I also tried to move the 3 lines at the
beginning of the sliderMoved method, still no luck...apparently it's
not the binding thats keeping it from working I guess?

Thanks for the info, I found the piece of code you were referring
to, but somehow I can't get it to work... here's my code:
- (IBAction)sliderMoved:(id)sender {
SEL trackingEndedSelector = @selector(sliderEnded:);
[NSObject cancelPreviousPerformRequestsWithTarget:self
selector:trackingEndedSelector object:sender];
[self performSelector:trackingEndedSelector withObject:sender
afterDelay:0.0];
// do whatever you want to do during tracking here
[self willChangeValueForKey:@"imageContrast"];
imageContrast = [sender doubleValue];
[self didChangeValueForKey:@"imageContrast"];
}
- (void)sliderEnded:(id)sender {
// do whatever you want to do when tracking ends here
NSLog(@"Done tracking");
}
My label is bound to imageContrast so that it is updated live....
right now I'm only trying to log a message when the tracking is
done... my slider is connected to the sliderMoved action... did I
do anything wrong? Right now when I move the slider I get a ton of
"Done tracking" messages in the console, and my label is never
updated.. which is... well, almost the opposite of what should
happen....
This trick works for me, but I have not combined it with bindings.
What happens if you comment out the 3 lines that are updating
imageContrast, do you still get "Done tracking" messages during
tracking?
