  • 设置slider当前位置的图像

        [slider setThumbImage:[UIImage imageNamed:@"dd.png"] forState:UIControlStateNormal];
    
  • 设置起始的颜色

    [slider setMinimumTrackTintColor:[ComHelper colorWithHex:SYSTEM_BLUE_COLOR]]
    
  • 设置末尾的颜色

    [slider setMaximumTrackTintColor:[UIColor colorWithRed:0 green:0 blue:0 alpha:0.5]]
    
  • 设置为竖直的

    slider.transform = CGAffineTransformMakeRotation(-M_PI_2);
    
  • 重新设置slider的frame,并且设置为数值的
    一定要先设置transform为标准的,在设置frame,再设置transform

        slider.transform = CGAffineTransformIdentity;
        slider.frame = CGRectMake(0, 0, sliderLength, 20);
        [slider setCenter:CGPointMake(xCenter, yCenter)];
        slider.transform = CGAffineTransformMakeRotation(-M_PI_2);
