Ich erschaffeUISlider Programmatisch. Ich versuche, @ anzupassUISlider Wert wie 4,1, 4,2, 4,3, 4,4, 4,5, 5,0, 5,1, 5,2, 5,3, 5,4, 5,5, 6,0, ... Jeder gibt mir die Lösung

sliderDemo = UISlider(frame:CGRectMake(0, 0, 200,20))
    var numberOfSteps : NSInteger = numbers.count - 1
    sliderDemo.minimumValue = 6.5
    sliderDemo.maximumValue = 4.1
    sliderDemo.continuous = true
    sliderDemo.value = 4.0
    sliderDemo.addTarget(self, action: "sliderValueDidChange:", forControlEvents: .ValueChanged)
    self.view.addSubview(sliderDemo)

func sliderValueDidChange(sender:UISlider!)
{
    println("number:\(sender.value)")
}
