UISlider in UIToolbar -> can't get slider.value and process it. iOS SDK
===

I'm trying to get a UISlider into my UIToolbar and to take the value from it and process it.  I also want to be able to change the slider.value via other methods.
So, I set it up for the UISlider by it's self (not on a UIToolBar) and everything worked fine.  Then, when I put it into the UIToolBar, the value stopped getting sent to and from it (I am NSLogging it whenever it changes and I keep getting 0 returned to me).
Here's the relevant section of my code - does anybody have any ideas?

    - (void)setupToolBarAndSlider {
        CGRect frame = CGRectMake(0.0, 0.0, 200.0, 30.0);
        UISlider *slider = [[UISlider alloc] initWithFrame:frame];
        [slider addTarget:self action:@selector(sliderValueChanged) forControlEvents:UIControlEventValueChanged];
        [slider setBackgroundColor:[UIColor clearColor]];
        slider.minimumValue = 0;
        slider.maximumValue = 8;
        slider.continuous = YES;
        slider.value = questionNumberForArray;
        //Change slider for UIToolbar
        UIBarButtonItem *skipQuestionSlider = [[UIBarButtonItem alloc] initWithCustomView:slider];
        // Set the width of aSlider
        [skipQuestionSlider setWidth:400.0];
        //Set up UIToolBar with Slider in it.
        UIToolbar *toolBar;
        CGRect rect2 = CGRectMake(0, toolBar.frame.origin.y , self.view.frame.size.width , 44);
        toolBar = [[UIToolbar alloc]initWithFrame:rect2];
        toolBar.barStyle = UIBarStyleBlackTranslucent;
        [toolBar setItems:[NSArray arrayWithObjects:skipQuestionSlider, nil]];
        [self.view addSubview:toolBar];
    }
    - (void)sliderValueChanged {
        NSInteger roundedSliderNumber = round(skipQuestionSlider.value);
        NSLog(@"Slider Value = %d", roundedSliderNumber);
    }
