1.UISwitch

开关视图,可以让用户快速的开关一个功能,比如蓝牙,wif等.

系统默认样式:

上面绿色的开启状态,下面的是关闭状态.

UISwitch的构成部分:

//MARK: initSwitchView
    var coun : NSInteger = 0
    func initSwitchView() {
        let testSwitch = UISwitch.init(frame: CGRectMake(100,100,51,31))
        self.view.addSubview(testSwitch)
        
        //        testSwitch.on = true  // 设置开关状态
        //        testSwitch.onTintColor = UIColor.redColor()
        testSwitch.tintColor = UIColor.blueColor()
        testSwitch.thumbTintColor = UIColor.redColor()
        testSwitch.setOn(true,animated: true) // 设置动画
        
        
        testSwitch.addTarget(self,action: #selector(ViewController.UISwitchValueChange),forControlEvents:UIControlEvents.ValueChanged)
    }
//MARK: UISwitchValueChange 事件
    func UISwitchValueChange() {
        self.coun = self.coun + 1
        print("\(self.coun)")
    }

拖一个控件在IB中,我们看看

这个控件比较简单,一般使用系统样式就可以了,主要是增加值改变事件.

2.UIProgressView

UIProgressView进度条样式.默认最小值是0,最大值是0且不可以改变.

UIProgressView的构成部分:

UIProgressView的样式:

UIProgressView的高度也是固定的,固定值是2.

//MARK: initProcessView
    func initProcessView() {
        let testProcessView = UIProgressView.init(frame: CGRectMake(60,150,200,2))
        self.view.addSubview(testProcessView)
        
        testProcessView.tag = 1;
//        testProcessView.progress = 0.8
//        testProcessView.progressImage = UIImage.init(named: "1")
//        testProcessView.progressTintColor = UIColor.redColor()
//        testProcessView.trackTintColor = UIColor.greenColor()
//        testProcessView.trackImage = UIImage.init(named: "2")
//        testProcessView.progressViewStyle = .Bar  //样式
        
        NSTimer.scheduledTimerWithTimeInterval(1,target: self,selector: #selector(ViewController.UIProgressViewvalueChange),userInfo: nil,repeats: true)
    }
//MARK: UIProgressViewvalueChange 事件
    func UIProgressViewvalueChange() {
        let testProcessView = self.view.viewWithTag(1) as! UIProgressView
        if testProcessView.progress == 1 {
            testProcessView.progress = 0
        }
        testProcessView.progress = testProcessView.progress + 0.05
    }

UiSlider感觉就是在UIProgressView的上面增加了一个用户可以手动控制的按钮,且最大值和最小值都可以由用户自行设置.

UiSlider的构成:

UiSlider的高度默认是31,我们看看UISwitch就知道了,它们有点联系了.

//MARK: initSliderView
    func initSliderView() {
        let testSlider = UiSlider.init(frame: CGRectMake(60,31))
        self.view.addSubview(testSlider)
        
        testSlider.minimumValue = 0    //设置最小值
        testSlider.maximumValue = 100  //设置最大值
//        testSlider.value = 10          //设置当前值
        testSlider.setValue(20,animated: true) // 设置当前值 是否加动画效果
        testSlider.continuous = true
        testSlider.minimumValueImage = UIImage.init(named: "1")
        testSlider.maximumValueImage = UIImage.init(named: "2")
        testSlider.thumbTintColor = UIColor.redColor()
        testSlider.addTarget(self,action: #selector(ViewController.UiSliderValueChage),forControlEvents: UIControlEvents.ValueChanged)
    }
//MARK: UiSliderValueChage 事件
    func UiSliderValueChage(testSlider : UiSlider) {
        print("\(testSlider.value)")
    }
