用于解析 html 的正则表达式；

你能帮我制作正则表达式吗？在大字符串中，我需要找到这些子字符串（2种格式）：

http://www.facebook.com/profile.php?id=100002234024152&ref=ffa\ http://www.facebook.com/alesya.yuldasheva?ref=ffa\

我尝试了这些：

@"\\b(https?):\/\/www.facebook.com([.]{*})ref=ffa";
@"[{http:\/\/www.facebook.com}([.]{*}){ref=ffa}]";
@"[http:\/\/www.facebook.com]([.])*[ref=ffa]";

我使用 RegexKitLite，其语法与正常的 Objective C 正则表达式相同。
