[iOS] UISlider 改变滑块的大小

// 滑块颜色
sliderForMV.thumbTintColor = [UIColor whiteColor];

// 走过的进度条的颜色
sliderForMV.minimumTrackTintColor = [UIColor colorWithRed:54 / 256.0 green:148 / 256.0 blue:111 / 256.0 alpha:1];

// 将滑块赋图片 图片的大小就是显示的大小

// 通常状态下
[sliderForMV setThumbImage:[UIImage imageNamed:@"iconfont-yuandian"] forState:UIControlStateNormal];

// 滑动状态下
[sliderForMV setThumbImage:[UIImage imageNamed:@"iconfont-yuandian"] forState:UIControlStateHighlighted];
