UiSlider does not have this property of 

popUpViewCornerRadius

Either remove this line else this property would be included in the Custom class.

So change the UISlider *slider1 to ASValueTrackingSlider *slider1

When you are allocating self.slider you need to use ASValueTrackingSlider instead of UISlider.

if you are using story board or xib you need to give ASValueTrackingSlider in identity inspector. like enter image description here

http://cocoadocs.org/docsets/ASValueTrackingSlider/0.9.2/Classes/ASValueTrackingSlider.html refer the link.

UISlider doesn't have this property popUpViewCornerRadius, because of that this error is occurring. You will need to remove this below line.

self.slider1.popUpViewCornerRadius = 25.0;
