iOS Development Tips-use UISlider to adjust the range of values

(Swift)

Import UIKitclassViewcontroller:uiviewcontroller {var slider:uislider!func slidervaluechanged (slider:uislider) {println ("Slider ' s new value is \ (slider.value)")    }        Overridefunc viewdidload () {super.viewdidload () slider= UISlider (Frame:cgrect (x:0Y:0, Width: $, Height: at)) Slider.center=View.center Slider.minimumvalue=0Slider.maximumvalue= -Slider.value= Slider.maximumvalue/2.0                //Customize slider and highlighted with own imageSlider.setthumbimage (UIImage (named:"Thumbnormal"), Forstate:. Normal) Slider.setthumbimage (UIImage (named:"thumbhighlighted"), Forstate:. Highlighted) Slider.addtarget (Self, Action:"slidervaluechanged:", forControlEvents:. valuechanged) View.addsubview (Slider)}}
