weiboSDK登录分享

关于这个分享，也是考虑到很多开发者，在使用的过程中遇到的了很多的问题，对于这种情况我是这么理解的，微博也许是做事不认真吧，也许是我们真的不懂吧，但是我觉得解决问题，能达到自己想要的效果就好了。微博官方的weiboSDK我用的是最新的版本，截止到目前这个时刻，我是用的是最新的，开始的时候，我使用的时候，使用了最初的UIWebView的登录方式，主要是因为，使用客户端的方式，至今不知道什么原理，自己还是慢慢研究吧，呵呵。后来觉得样式不符合自己，于是今天就自己使用UIViewController，在里面使用UIWebView的方式，简单的实现了，至少现在的看起来不会感觉手机的登录看起来怪怪 的。我把代码留在下面：
