UISlider problem - how to identify the user releasing the slider button in iOS?

I can detect the value change event from UISlider, but now I need to detect the user releasing the slider button.

How to detect this event (or touch the slider contours)?

Should I use the "touch in" event to detect?

Thank.

I did not work with sliders, however, since UISlider inherits from UIView, you can just click on touchhesBegan: and touchhesEnded: to complete your task.
