Change a UILabels text with a UISliders value

Question

How I could show a UISliders value as a UILabels text?

Answer 1

Add an action to the slider, like this:

[slider addTarget:self action:@selector(sliderChanged:) forControlEvents:UIControlEventValueChanged];

Where the sliderChanged: method looks something like this:

- (void)sliderChanged:(UISlider *)slider {
    self.label.text = [NSString stringWithFormat:@"%g", slider.value];
}
