本文介绍如何使用UCloud SDK结合GCD的group队列实现iOS应用中多图的异步上传，通过FBBasicUploadModel封装上传逻辑，包括上传状态、进度回调及错误处理。

最近开发项目中，用到ucloud上传多图，使用GCD的group队列，进行多图异步上传，提高上传速度。调用如下：

//ucloud多图上传封装

- (void)uploadMultiPic

{

NSMutableArray *uploadImageArr = [NSMutableArray array];

//创建group

dispatch_group_t uploadGroup = dispatch_group_create();



for (int i = 0; i<_toUploadImageArr.count;i++) {

FBAttachmentCellStyleModel *model = _toUploadImageArr[i];

dispatch_group_enter(uploadGroup);

[model uploadSuccess:^(id obj) {

NSLog(@"上传图片成功:%d url:%@",i,obj);

FBBasicUploadModel *model = [[FBBasicUploadModel alloc] init];

model.imgUrl = obj;

model.index = [NSString stringWithFormat:@"%d",i];

[uploadImageArr addObject:model];

dispatch_group_leave(uploadGroup);

} progress:^(CGFloat p) {



} failure:^(NSError *error) {

dispatch_group_leave(uploadGroup);

}];

}



if (_sortImageArray != nil) {

[_sortImageArray removeAllObjects];

}

//全部上传完整理图片数组

@weakify(self);

dispatch_group_notify(uploadGroup, dispatch_get_main_queue(), ^{

   [MBProgressHUD hideHUDForView:nil];

@strongify(self)

for (int i=0;i<uploadImageArr.count;i++) {

for (FBBasicUploadModel *model in uploadImageArr) {

if ([model.index intValue] == i) {

[self->_sortImageArray addObject:model.imgUrl];

}

}

}

//提交ucloud返回图片url数组给服务器

[self publish];

});

}

其中用到ucloud上传，做了一层封装，FBAttachmentCellStyleModel继承于FBBasicUploadModel，FBBasicUploadModel实现文件如下：

#import <UIKit/UIKit.h>

#import "UFileSDK.h"

/**

上传状态

*/

typedef NS_ENUM(NSInteger, YBAttachmentUploadStatus) {

/**未上传*/

YBAttachmentUploadStatusNone = 0,

/**上传中*/

YBAttachmentUploadStatusUploading,

/**上传结束*/

YBAttachmentUploadStatusEnd,

};

@interface FBBasicUploadModel : NSObject

@property (nonatomic, strong) UFileSDK* ufilesdk;

@property (nonatomic, strong) NSString *imageName;

@property (nonatomic, strong) NSString *imagePath;

@property (nonatomic, strong) NSString *imageType;

/**上传成功后返回的url*/

@property (nonatomic, copy) NSString *imgUrl;

/**选择后的图片*/

@property (nonatomic, strong) UIImage *image;

/**上传状态*/

@property (nonatomic, assign) YBAttachmentUploadStatus uploadStatus;

/**进度0~1*/

@property (nonatomic, assign) CGFloat progress;

/**当前是第几张图片*/

@property (nonatomic, copy) NSString *index;

/**进度回调*/

@property (nonatomic, copy) void(^UploadProgress)(CGFloat p);

/**成功回调*/

@property (nonatomic, copy) void(^UploadSuccess)(id obj);

/**失败回调*/

@property (nonatomic, copy) void(^UploadFailure)(NSError *error);

/*!

@method

@brief ucloud上传图片

@param success 成功回调

@param imageProcess 图片上传进度回调

@param failure 失败回调

*/

- (void)uploadSuccess:(void(^)(id obj))success

progress:(void(^)(CGFloat p))imageProcess

failure:(void(^)(NSError *error))failure;

@end

#import "UFileAPIUtils.h"

@implementation FBBasicUploadModel

- (UFileSDK *)ufilesdk

{

if (_ufilesdk == nil) {

_ufilesdk = [[UFileSDK alloc] initWith:bucket ProxySuffix:proxySuffix PublicKey:publicToken PrivateKey:privateToken];

}

return _ufilesdk;

}

- (void)uploadSuccess:(void(^)(id obj))success

   progress:(void(^)(CGFloat p))imageProcess

failure:(void(^)(NSError *error))failure

{

self.uploadStatus = YBAttachmentUploadStatusUploading;





NSString* strkey = [NSString stringWithFormat:@"%@.%@",self.imageName,self.imageType];

   NSString * strPath = [[NSBundle mainBundle] pathForResource:@"initscreen" ofType:@"jpg"];

if (self.imagePath != nil) {

strPath = self.imagePath;

}

else{

strPath = [[NSBundle mainBundle] pathForResource:self.imageName ofType:self.imageType];

}

NSData* contentData = [[NSData alloc] initWithContentsOfFile:strPath];



   // NSString* contentType = @"image/jpeg";

NSString* contentType = [NSString stringWithFormat:@"image/%@",self.imageType];



NSString* contentMD5 = [UFileAPIUtils calcMD5ForData:contentData];





NSString* strAuth = [self.ufilesdk calcKey:@"PUT" Key:strkey MD5:contentMD5 ContentType:contentType CallBackPolicy:nil];



//上传参与签名计算要传authorization 生成的签名

//上传参与签名计算要传data 文件内容

//上传参与签名计算要传option 其他参数

//option[kUFileSDKOptionFileType]=contentType 文件类型

//option[kUFileSDKOptionMD5]=contentMD5 文件内容md5

NSDictionary * option = @{kUFileSDKOptionFileType: contentType, kUFileSDKOptionMD5: contentMD5};



[self.ufilesdk.ufileApi putFile:strkey

authorization:strAuth

   option:option

   data:contentData progress:^(NSProgress* progress){

   imageProcess(progress.fractionCompleted);

   }

success:^(NSDictionary* response){

if(response)

{

//自己拼接https://imguf.****.cn+图片名（包含图片格式） https://imguf.****.cn/initscreen.jpg

NSString *imageUrl = [NSString stringWithFormat:@"%@%@",imageHost,strkey];

   // NSLog(@"image url:%@",imageUrl);

success(imageUrl);

}

}

failure:^(NSError* error){



NSString*erMsg = @"";

if (error && error.domain == kUFileSDKAPIErrorDomain) {

erMsg = error.userInfo[@"ErrMsg"];

}

else

{

erMsg = error.description;

}

failure(error);

}];

}
