UISlider

创建UISlider

let slider = UISlider(frame: CGRectMake(50, 100, 280, 50))
slider.backgroundColor = UIColor.clearColor()
slider.minimumValue = 0//最小值
slider.maximumValue = 1//最大值
slider.value = 0.3//当前值
self.view.addSubview(slide

设置滑块样式Highlighted+Normal

 slider.setThumbImage(UIImage(named: "+1"), forState: UIControlState.Highlighted)
slider.setThumbImage(UIImage(named: "+1"), forState: UIControlState.Normal)

设置滑块左右颜色

slider.minimumTrackTintColor=UIColor.orangeColor()//左边槽的颜色
slider.maximumTrackTintColor=UIColor.grayColor() //右边槽的颜色

滑条两侧添加图标

slider.minimumValueImage=UIImage(named:"-1")  //左边图标
slider.maximumValueImage=UIImage(named:"+1")  //右边图标

设置滑槽左边和右边的图片的

slider.setMinimumTrackImage(UIImage(named: "-1"), forState: UIControlState.Normal)
slider.setMaximumTrackImage(UIImage(named: "-1"), forState: UIControlState.Normal)

设置滑块右边部分的图片-使用三宫格缩放（左右14像素不变，中间缩放）

let imgTrackRight = UIImage(named:"+1")
let imgRight = imgTrackRight!.stretchableImageWithLeftCapWidth(14, topCapHeight:0)
slider.setMaximumTrackImage(imgRight, forState:UIControlState.Normal)

　　

slider.setValue(0.8, animated: true) //设置滑块的状态值+动画
slider.continuous = true//滑块滑动时后执行valueChange  false :停止滑动后执行, default = YES
slider.addTarget(self, action: Selector("sliderChange:"), forControlEvents: UIControlEvents.ValueChanged)

func sliderChange(slider: UISlider){
    print(slider.value)
}
