要自定义 UISlider，请使用本教程中的这段代码。

UIImage *minImage = [[UIImage imageNamed:@"slider_minimum.png"] 
    resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 0)];
UIImage *maxImage = [[UIImage imageNamed:@"slider_maximum.png"] 
    resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 0)];
UIImage *thumbImage = [UIImage imageNamed:@"thumb.png"];

     [[UISlider appearance] setMaximumTrackImage:maxImage 
        forState:UIControlStateNormal];
    [[UISlider appearance] setMinimumTrackImage:minImage 
        forState:UIControlStateNormal];
