一、数据模型

@interface SSTEditTaskSujectFinishedPictureModel:NSObject

/**
 * 图片上传的日期
 */
@property (nonatomic,copy) NSString *uploadDate;

/**
 * 图片关联的科目
 */
@property (nonatomic,copy) NSString *course;

/**
 * 图片关联的学生
 */
@property (nonatomic,copy) NSString *vipId;

@property (nonatomic,copy) NSString *studentName;

/**
 * 图片id
 */
@property (nonatomic,copy) NSString *homeworkPictureId;

/**
 * 图片id 对比前后端的数据是否重复问题
 */
@property (nonatomic,copy) NSString *derverFileId;

@property (nonatomic,copy) NSString *timestampStr;

/**
 * 图片路径
 */
@property (nonatomic,copy) NSString *image;

@property (nonatomic,copy) NSString *originImageUrl;

@property (nonatomic,copy) NSString *originPictureUrl;

/**
 * 图片批注状态，0默认，1批注， 2补拍，3不全, 4模糊，5上传中(本地管理) ，6上传失败(本地管理) ，7未上传(本地管理)
 */
@property (nonatomic,assign) SSTHomeworkPictureState correctStatus;

/**
 * 图片的本地路径
*/
@property (nonatomic,copy) NSString *localPath;

/**
 * 本地上传的图片
*/
@property (nonatomic,strong) UIImage *localImage;

/**
 * 是否是本地 0:服务器 1：本地
 */
@property (nonatomic,assign)BOOL isLocalData;

/**
 * 序号
 */
@property (nonatomic,assign)int index;

/**
 * 推荐题目记录Id
 */
@property (nonatomic,copy) NSString *questionRecommendRecordId;

@end

                                [[DataBaseHelper sharedInstance] updateImageModel:imageModel withImageModelKey:@"correctStatus" andImageModelValue:@"6"];

                            }
                            [weakSelf uploadNextImageModel]; // 上传下一张

                    [[DataBaseHelper sharedInstance] updateImageModel:imageModel withImageModelKey:@"correctStatus" andImageModelValue:@"6"];
                    [weakSelf uploadNextImageModel]; // 上传下一张

        });

    }else { // 如果有imageModel
        self.isUploading = NO;
    }
    
}

@end

四、拍照上传操作

    // 上传作业图片
    SSTEditTaskSujectFinishedPictureModel *subjectFinishPictureModel = [[SSTEditTaskSujectFinishedPictureModel alloc] init];
    NSTimeInterval endTime = [[NSDate date] timeIntervalSince1970]*1000;// *1000 是精确到毫秒，不乘就是精确到秒
    NSInteger uploadTime = endTime;
    NSString *localImagePath = [NSString stringWithFormat:@"%@-%zd.jpg",[SSUtility getUserVipId],uploadTime];
    subjectFinishPictureModel.course = self.subject;
    subjectFinishPictureModel.vipId = [SSUtility getUserVipId];
    //subjectFinishPictureModel.uploadDate = [NSDate getDate:[NSDate date] day:4]; // 测试
    subjectFinishPictureModel.uploadDate = [NSDate getDateStringWithNowDate:[NSDate date]];
    subjectFinishPictureModel.derverFileId = [NSString stringWithFormat:@"%@-%zd",[SSUtility getUserVipId],uploadTime];
    subjectFinishPictureModel.localPath = localImagePath;
    subjectFinishPictureModel.timestampStr = [NSString stringWithFormat:@"%zd",uploadTime];
    subjectFinishPictureModel.localImage = _photopImage;
    subjectFinishPictureModel.correctStatus = SSTHomeworkPictureStateUploading; // 上传中
    subjectFinishPictureModel.studentName = [SSUtility getUserCurrentChildName];
    //subjectFinishPictureModel.isLocalData = YES;
    //[[SSTUploadHomeworkPictureManager shareManager] saveUploadingHomewrokPhoto:subjectFinishPictureModel withVipId:self.vipId subject:self.courseName];

    [[SSImageUploadQueueManager shareManager] enqueueImageModel:subjectFinishPictureModel];

五、上传列表数据获取

    NSArray *uploadImgAllArr = [[DataBaseHelper sharedInstance] getAllHomeworkImageModel];
    NSMutableArray *uploadImgErrorArr = [NSMutableArray array];
    for (SSTEditTaskSujectFinishedPictureModel *imageModel in uploadImgAllArr) {
        if (imageModel.correctStatus == SSTHomeworkPictureStateUploadFail) {
            [uploadImgErrorArr addObject:imageModel];
        }
    }
    [self.uploadImgArr removeAllObjects];
    [self.uploadImgArr addObjectsFromArray:uploadImgAllArr];
    [self.uploadImgErrorArr removeAllObjects];
    [self.uploadImgErrorArr addObjectsFromArray:uploadImgErrorArr];
    dispatch_async(dispatch_get_main_queue(), ^{
        self.rightBtn.hidden = uploadImgErrorArr.count > 0 ? NO : YES;
        [self.tableView reloadData];
    });
