由于七牛没有批量上传的方法，找了很多博客，最终完成了批量上传，发篇文章记录一下
借鉴了这位朋友的大部分代码 http://www.jianshu.com/p/cdca6bb059de
TMUploadImageTools.h实现

//单张图片上传
+ (void)uploadImage:(UIImage *)image progress: (QNUpProgressHandler)progress success:(void(^)(NSString*url))success failure:(void(^)())failure;
//多张图片上传
+ (void)uploadImages:(NSArray*)imageArray progress:(void(^)(CGFloat))progress success:(void(^)(NSArray*))success failure:(void(^)())failure;

@implementation TMQiNiuUploadHelper
static id _instance = nil;

以上的QiNiuBaseUrl是在七牛后台获取，像后台开发人员要，我这个是测试用的

QiNiuToken 也是要通过网络获取，通过调用自己的网络工具类来动态获取token；我这个token是写死的，token会过期，返回info.statusCode == 401。
