Upload notes for images and videos

Upload notes for images and videos

Image uploading is often used in our development, such as the upload of an avatar, and publishing multiple images in the release space. Here, I use network resources for reference, it also relies on qiniu cloud storage to make a summary of Image Upload.

I first encapsulated a tool class for Image Upload, which is inherited from nsobject and named QiniuTool. When uploading multiple images, I also need to process the upload result of a single image. Therefore, here I have created an auxiliary tool class named QiniuUploadHelper;

Tool class method:

# Import <Foundation/Foundation. h> // upload a video and n images # import <QiniuSDK. h> # import <UIKit/UIKit. h> typedef enum {type_image, type_video} LoadType; @ interface QiniuTool: NSObject // get qiniu upload token + (void) getQiniuUploadToken :( LoadType) type loadUrl :( NSString *) tokenUrl result :( void (^) (NSDictionary * token) success failure :( void (^) () failure; /** upload the video @ param videoPathUrl the local URL of the video * // + (void) uploadVedio :( NSURL *) videoPathUrl success :( void (^) (NSMutableDictionary * result )) success failure :( void (^) () failure; /** upload a single image @ param progress upload progress @ param success callback @ param failure callback */+ (void) uploadImage :( UIImage *) image loadUrl :( NSString *) tokenUrl progress :( QNUpProgressHandler) progress success :( void (^) (NSString * url) success failure :( void (^) () failure; // upload multiple images by queue + (void) uploadImages :( NSArray *) imageArray loadUrl :( NSString *) tokenUrl progress :( void (^) (CGFloat )) progress success :( void (^) (NSArray * urlArray) success failure :( void (^) () failure; @ end
