Swift的UISlider使用

var slider = UISlider()

var timer = NSTimer()

slider.frame = CGRectMake(10, 200, view.frame.size.width-20, 100)

slider.backgroundColor = UIColor.lightGrayColor()

slider.minimumValue = 0

slider.maximumValue = 100

slider.value = 0

slider.addTarget(self, action: #selector(ViewController.sliderClicked), forControlEvents: UIControlEvents.ValueChanged)

self.view.addSubview(slider)

timer = NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector: #selector(ViewController.tiemsClicked), userInfo: nil, repeats: true)

func tiemsClicked() {

slider.value += 1

if (slider.value == 100) {

slider.value = 0

timer.invalidate()

}

}

func sliderClicked() {

print(self.slider.value)

if (slider.value == 100) {

slider.value = 0

}

}
