UISlider Finished Changing

Question

I have a slider that when it begins to change the values, another label shows up (lets the user see what they are doing). The only problem is that I need to know when the user has finished editing the slider so I can make that UILabel go away again. Is there a way to do this? The code below shows what I do when the sliders value begins to change. Thank you for you help!

- (IBAction)sliderValueChanged:(UISlider *)sender {
    tipPercentLabel.text = [NSString stringWithFormat:@"%.f", ([sender value] * 100)];
    tipPercentLabel2.text = [NSString stringWithFormat:@"%.f", ([sender value] * 100)];

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:1.0];
    [tipPercentLabel setAlpha:0.3];
    [tipPercentLabel2 setAlpha:1.0];
    [UIView commitAnimations];


    [self performSelector:@selector(autoTipCalc) withObject:nil afterDelay:0.01];
}

Answer 1

You have already added one target/action pair for UIControlEventValueChanged, all you need to do is call addTarget:action:forControlEvents: again with a different selector and a control event of UIControlEventTouchUpInside (or any other that you're interested in).
