swift中UISlider的使用

概述let slider = UISlider(frame: CGRectMake(10.0,10.0, (CGRectGetWidth(self.view.bounds) - 10.0 * 2), 20.0))self.view.addSubview(slider)slider.backgroundColor = UIColor.lightGrayColor() // 设置值（默认值为0.0，且

let slIDer = UiSlider(frame: CGRectMake(10.0,10.0,(CGRectGetWIDth(self.vIEw.bounds) - 10.0 * 2),20.0))self.vIEw.addSubvIEw(slIDer)slIDer.backgroundcolor = UIcolor.lightGraycolor()

// 设置值（默认值为0.0，且值区间为0.0~1.0）slIDer.minimumValue = 1.0slIDer.maximumValue = 100.0slIDer.setValue(20.0,animated: true)

// 注意：滑动条大小值（minimumTrackTintcolor、maximumTrackTintcolor）颜色与大小值左右两端图标（minimumValueImage、maximumValueImage）不能同时设置，否则图标设置无效slIDer.minimumValueImage = UIImage(named: "normalimage")slIDer.maximumValueImage = UIImage(named: "hightimage")

// 注意：滑动条大小值颜色（minimumTrackTintcolor、maximumTrackTintcolor）与滑动条大小值图标（setMinimumTrackImage、setMaximumTrackImage）不能同时设置，否则先设置的无效// slIDer.setMinimumTrackImage(UIImage(named: "normalimage"),forState: UIControlState.normal)// slIDer.setMaximumTrackImage(UIImage(named: "hightimage"),forState: UIControlState.normal)        slIDer.minimumTrackTintcolor = UIcolor.yellowcolor()slIDer.maximumTrackTintcolor = UIcolor.redcolor()

// 滑动块颜色、或图标设置（注意：两者不能同时设置，否则先设置的无效。另外，默认thumb块比较大，可通过设置thumbImage的方法改变thumb大小）slIDer.thumbTintcolor = UIcolor.greencolor()slIDer.setThumbImage(UIImage(named: "hightimage"),forState: UIControlState.normal)slIDer.setThumbImage(UIImage(named: "hightimage"),forState: UIControlState.Highlighted)

// 滑块滑动停止后才触发ValueChanged事件slIDer.continuous = false// 响应事件slIDer.addTarget(self,action: Selector("slIDerValueChange:"),forControlEvents: UIControlEvents.ValueChanged)

let label = UILabel(frame: CGRectMake(10.0,(CGRectGetMinY(slIDer.frame) + CGRectGetHeight(slIDer.bounds) + 10.0),(CGRectGetWIDth(self.vIEw.frame) - 10.0 * 2),30.0))self.vIEw.addSubvIEw(label)label.backgroundcolor = UIcolor.yellowcolor()label.textcolor = UIcolor.redcolor()label.tag = 1000let value = slIDer.valuelabel.text = String(format: "slIDer当前值是：%.2f",arguments: [value])

// MARK: - slIDerValueChangefunc slIDerValueChange(slIDer:UiSlider){        let value = slIDer.value        let label:UILabel = self.vIEw.vIEwWithTag(1000) as! UILabel        label.text = String(format: "slIDer当前值是：%.2f",arguments: [value])        print("slIDer当前值是：\(value)")}
