圖片、視頻上傳小記，視頻上傳小記

      我們開發中常用到圖片上傳，比如頭像上傳之類的，還有類似發布空間說說時發布多張圖片等等，我在這裡通過借鑒網路資源，並依賴於七牛雲端儲存做了一個圖片上傳的小結。

      我首先封裝了一個圖片上傳的工具類，繼承自nsobject，命名為QiniuTool；再多圖上傳時，還需要單張圖片的上傳結果處理，因此，我在這裡有多建立了一個協助工具輔助類，命名為QiniuUploadHelper；

工具類類方法：

#import <Foundation/Foundation.h>//上傳 視頻 、n 張圖片#import <QiniuSDK.h>#import <UIKit/UIKit.h>typedef enum {    type_image,    type_video}LoadType;@interface QiniuTool : NSObject//擷取七牛上傳token+ (void)getQiniuUploadToken:(LoadType)type loadUrl:(NSString *)tokenUrl result:(void(^)(NSDictionary *token))success failure:(void(^)())failure;/** 上傳視頻 @param videoPathUrl 視頻的本地URL路徑 *///+ (void)uploadVedio:(NSURL *)videoPathUrl success:(void(^)(NSMutableDictionary *result))success failure:(void(^)())failure;/** 上傳單張圖片 @param image 圖片 @param progress 上傳進度 @param success 成功回調 @param failure 失敗回調 */+ (void)uploadImage:(UIImage*)image loadUrl:(NSString *)tokenUrl progress:(QNUpProgressHandler)progress success:(void(^)(NSString*url))success failure:(void(^)())failure;//上傳多張圖片,按隊列依次上傳+ (void)uploadImages:(NSArray*)imageArray loadUrl:(NSString *)tokenUrl progress:(void(^)(CGFloat))progress success:(void(^)(NSArray*urlArray))success failure:(void(^)())failure;@end
