今天使用Xcode自带的svn客户端时，总是连接不上服务器，报如下错误：
Error validating server certificate for ‘https://svn2.assembla.com:443’: – The certificate is not issued by a trusted authority. Use the fingerprint to validate the certificate manually!
Certificate information: – Hostname: *.assembla.com – Valid: from Thu, 24 Mar 2011 19:30:40GMT until Sun, 24 Mar 2013 19:30:40 GMT – Issuer: 07969287, http://certificates.godaddy.com/repository, GoDaddy.com, Inc., Scottsdale, Arizona, US – Fingerprint: ae:b0:b6:94:14:5f:4b:28:d2:82:68:ae:e9:18:85:b3:ea:36:ee:f2
解决办法：
1、打开终端（实用工具 -->终端），在终端中输入如下命令（注意下面的url更换成你自己的url地址）：
svn ls https://82.100.10.11?0/svn/Superscou
2、然后会出现一个服务器证书的提示，根据提示输入 “p”，然后回车，问题就可以得到解决了
