(iOS)七牛批量上传图片

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
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
#import <QiniuSDK.h>

@interface TMUploadImageTools : NSObject
//获取七牛上传token
+ (void)getQiniuUploadToken:(void(^)(NSString*token))success failure:(void(^)())failure;
    //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;

TMQiNiuUploadHelper.h

#import <Foundation/Foundation.h>

@interface TMQiNiuUploadHelper : NSObject

@property(copy,nonatomic) void(^singleSuccessBlock)(NSString*);

@property(copy,nonatomic) void(^singleFailureBlock)();

+ (instancetype)sharedUploadHelper;

@end

TMQiNiuUploadHelper.m

#import "TMQiNiuUploadHelper.h"

@implementation TMQiNiuUploadHelper

static id _instance = nil;

+ (id)allocWithZone:(struct _NSZone *)zone {

    static dispatch_once_t onceToken;

    dispatch_once(&onceToken, ^{
    
        _instance= [super allocWithZone:zone];
    
    });

    return _instance; 
}

+ (instancetype)sharedUploadHelper {

    static dispatch_once_t onceToken;

    dispatch_once(&onceToken, ^{
    
        _instance= [[self alloc]init];
    
    });

    return _instance;
}

- (id)copyWithZone:(NSZone*)zone {

    return _instance;

}
@end

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。
