I want to distinguish mobile web address ,pc web page address

I am giving a newslist link address by portal site open api.

I want to display these linked news on iPhone. Only mobile address link.

for(int i=0;i< [newsList count];i++)
{

  NewsItem *newsItem = (NewsItem *)[newsList objectAtIndex:i];
  const char *linkAddress = [newsItem.mLink UTF8String]; 

  if开发者_如何学运维(~~~)     //->here. I want to check a mobile address.
  {
    [NaverNewslist addObject:newsItem];

  }
}
self.mNewsList=NaverNewslist;

self.mSearchKey=searchkey;

}

Address Example

• pc web page

• mobile web page

So, I think these addresses conclude a convertible infomation to mobile.

How can I do this?

Try decoding the base64-encoded data in these URLs to see if you an extract valuable information, like a "isMobile" flag.
