ios 一个不错的图片浏览分享框架demo

demo功能：一个不错的图片浏览分享框架demo。iphone6.1 测试通过。可以浏览图片，保存，微博分享到新浪，腾讯，网易，人人等。

注：（由于各个微博的接口有时候会有调整，不一定能分享成功。只看框架，在找最新的官方分享接口将信息分享出去）

demo说明：主要代码在：PhotoViewController.m中。分享的各个接口在ShareSDK文件夹下。

框架用到了“SVProgressHUD” 第三方的控件来弹出提示层，提示 网络加载 或 提示对错。SVProgressHUD的具体说明；

和 “SDWebImage”类库来管理远程图片加载。SDWebImage的相关说明；
