UISlider *slider=[[UISlider alloc]initWithFrame:CGRectMake(100, 100, 200, 200)];
//最小值
slider.minimumValue=0;
//最大值
slider.maximumValue=100;
//当前值
slider.value=30;
//最大值、最小值图片
slider.maximumValueImage=[UIImage imageNamed:@"haha"];
slider.minimumValueImage=[UIImage imageNamed:@"xingxing"];
//最小值最大值轨道颜色；
slider.minimumTrackTintColor=[UIColor greenColor];
slider.maximumTrackTintColor=[UIColor yellowColor];
slider.continuous=YES;

//圆球颜色；
slider.thumbTintColor=[UIColor redColor];
//调用方法显示当前进度；
[slider addTarget:self action:@selector(sli:) forControlEvents:UIControlEventValueChanged];

[self.view addSubview:slider];

}

-(void)sli:(id)sender{
UISlider *slider=sender;
NSLog(@"%.2f",slider.value);
