经过互联网和科技的不断普及，人们的生活已经发生了翻天覆地的变化，几乎所有的行业都与互联网有所接轨，工作和生活也走向了科技化的道路。在大家日常生活中有许多显而易见的改变，各种新兴的娱乐方式也是充斥在互联网和生活之中，短视频直播平台就是个典型的例子。短视频平台之所以爆火是因为抓住了时代和人们的需求，这其中还有一定的科学依据，相关研究表明，人类在相同的单位时间内受到刺激程度会因为媒介产生变化，例如视频刺激会大于声音、图片、文字带来的刺激，短视频平台中五花八门的内容满足了人们的所有刺激需求，因此才会爆火，再就是短视频中的美颜滤镜SDK更是让人“流连忘返”，用过一次就再也忘不掉。

滤镜SDK接入短视频平台后展现出的效果非同凡响，它依靠图像增强技术，打造出多种不同风格的滤镜提供用户使用，例如：浪漫、清新、唯美、粉嫩等效果，用户可以使用多元化的滤镜实现不同风格的转变。很多用户经常向小编问起一个问题，“美颜滤镜SDK的代码是什么？”今天小编特意开一篇文章为大家解答一下。

• (void)configureUI {

  NSArray arr = @[@“美颜”,@“美型”/,@“滤镜”*/];
  if (_segmentControl) {
  return;
  }
  _segmentControl = [[WNSegmentControl alloc] initWithTitles:arr];

//slider 滑动修改对应的效果
