UISlider拇指图像在滑动时被隐藏

Question

I have set thumb image for UISlider. This image is not reflected when i drag the slider. Once I finish the dragging then It is appearing.

I have set the image for all states

    [self.myslider setThumbImage:[UIImage imageNamed:kPlayerScreenHandleImage] forState:UIControlStateNormal];
    [self.myslider setThumbImage:[UIImage imageNamed:kPlayerScreenHandleImage] forState:UIControlStateSelected];

Answer 1

Use UIControlStateHighlighted to Show thumb image while dragging.

like below.

[self.myslider setThumbImage:[UIImage imageNamed:kPlayerScreenHandleImage] forState:UIControlStateHighlighted];

Hope it helps..

Answer 2

You should set both images, that is while normal and also during highlight

 rangeSlider.setThumbImage(UIImage(named : "yourImage"), for: .normal)
 rangeSlider.setThumbImage(UIImage(named : "yourImage"), for: .highlighted)
