第三方分享，今天聊的是友盟分享，官方链接：http://www.umeng.com/social
官方的SDK都能看懂，并且没有什么大的坑，这里不再累述。这里简单的举个例子。
首先注意添加第三方依赖库，不然一片红。
需要添加的依赖库：Security.framework,libiconv.dylib,SystemConfiguration.framework,CoreGraphics.framework，libsqlite3.dylib，CoreTelephony.framework,libstdc++.dylib,libz.dylib
直接上代码，这只是一个小例子。不对的地方还请指正。

//url在实际项目开发中后台会给你一个url，如果你的应用已经在app store上线成功的话，也可以填写当前应用在app store的下载地址，如果填为nil，默认的设置为友盟的官方网站
