如何让用户看到UISlider的值？

Question

I added a UISlider in interface builder in my iOS application. Can I make it so that the user can see the value of a UISlider while he/she is altering it?

Is there an interface builder setting I can change to easily implement this, or must I implement an IBAction that alters a UILabel on the screen based on the slider's value?

Answer 1

将UISlider的valueChanged选择器连接到自定义IBAction并在该方法中设置一些UILabel的值

Answer 2

Yes there is. You can set an outlet of type

    IBOutlet UISlider *slider

in your view controller, then bind it to the slider. Then the value of the slider is always accessible through the slider.value property, even in other methods.
