创建RLKShapeSlider文件，继承自：UISlider,创建两个slider即可完成处理

import "RLKShapeSlider.h"

static const CGFloat kSliderBound = 20.0;

@interface RLKShapeSlider ()

@property (nonatomic) CGRect lastBounds;

@end

@implementation RLKShapeSlider

• (CGRect)trackRectForBounds:(CGRect)bounds {
  return CGRectMake(bounds.origin.x, bounds.origin.y, bounds.size.width, MAX(bounds.size.height, 2.0));
  }

• (CGRect)thumbRectForBounds:(CGRect)bounds trackRect:(CGRect)rect value:(float)value;
  {

  rect.origin.x = rect.origin.x;
  rect.size.width = rect.size.width;
  CGRect result = [super thumbRectForBounds:bounds trackRect:rect value:value];
  //记录下最终的frame
  _lastBounds = result;
  return result;
  }
  //检查是点击事件的点是否在slider范围内

• (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event {
  //调用父类判断
  BOOL result = [super pointInside:point withEvent:event];

  if (!result) {
  //如果不在slider范围内，扩充响应范围
  if ((point.x >= (_lastBounds.origin.x - kSliderBound)) &&
  (point.x <= (_lastBounds.origin.x + _lastBounds.size.width + kSliderBound)) &&
  (point.y >= -kSliderBound) &&
  (point.y < kSliderBound)) {
  //在扩充范围内
  return YES;
  }
  }

  //否则返回父类的结果
  return result;
  }
