GQYVerticalSlider
可以自定义背景图片和滑块的Slider，纵向（竖向）滑动
API 跟系统UISlider 类似
@property (nonatomic,strong)UIImage * minImage;
@property (nonatomic,strong)UIImage * maxImage;
@property (nonatomic,strong)UIImage * thumbImage;
@property(nonatomic) float value; // default 0.0. this value will be pinned to min/max
@property(nonatomic) float minimumValue; // default 0.0. the current value may change if outside new min value
@property(nonatomic) float maximumValue; // default 1.0. the current value may change if outside new max value
@property (nonatomic,copy)void (^touchSliderValueChange)(CGFloat value);
- (void)setValue:(float)value animated:(BOOL)animated;
使用：
GQYVerticalSlider *slider = [[GQYVerticalSlider alloc]initWithFrame:CGRectMake(100, 200, 20, 200)];
[self.view addSubview:slider];
slider.maximumValue = 100;
slider.minimumValue = 30;
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[slider setValue:44 animated:YES];
});
效果：
