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)
}
