How to remove the thumb of UISlider in iphone?

Question

我在相同的视图中有两个UISliders。我的要求是，当用户改变第一个滑块的值时，第二个滑块值应该根据它改变。所以，在第二个滑块中我想隐藏它的拇指。虽然我已经清楚了它的拇指颜色，用户可以看到。我该如何解决？

[_slider setThumbImage:[UIImage new] forState:UIControlStateNormal];

Simply set the image for the thumb to be nil

UIImage *empty = [UIImage new];
[theSlider setMinimumTrackImage:[UIImage alloc] forState:UIControlStateNormal];
[theSlider setMaximumTrackImage:[UIImage alloc] forState:UIControlStateNormal];

Simply go to xib select slider --> Utilities --> show attributes Inspectors --> Thumb Tint Colour (Clear Thumb tint colour)
