JavaScript判断iPhone型号机型及iPhone版本Identifier对照

要求：根据用户安装App后，返回的设备型号，判断iPhone版本

实现代码：

 function getModelValue(last_model) {
      // 如果last_model不包含"iPhone"，则直接返回原值
      if (!last_model.includes('iPhone')) {
        return last_model;
      }
    
      // 定义子字符串和对应值的全面映射
      const modelMap = {
        // ... (之前的映射内容保持不变)
