How to detect the event when I slide the UISlider(not release, keep slide), I know setContinues can do so.
But my slider can't be set to continues, because I need the slider change once a time(that is touch-slide-slide-...-slide-stop only change its value for one time). Is there any way can do this ?
It turns out It's my problem. I thought continous property set to YES will allow the UISlider to slide in float(While my value must be int, not float type).
self.progressSlider.continuous = YES; just call the value changed as long as the slider's value changed. It won't change the value to double.
self.progressSlider.continuous = No; When you're sliding the slider, value changed event won't be called until you release it.
