iOS SDK的分片上传的并行上传功能不能用哦

如题，测试发现，分片上传的并行上传功能接口是返回成功的，但是根据objectKey去访问上传的图片是提示错误的，不过串行上传是没有问题的。
我的并行核心代码是这样子的：
uploadPart.uploadPartData = tempPartData;
        OSSTask * uploadPartTask = [self.ossClient uploadPart:uploadPart];
        // 并行操作
        [uploadPartTask continueWithBlock:^id _Nullable(OSSTask * _Nonnull task) {
            if (!uploadPartTask.error) {
    OSSUploadPartResult * result = uploadPartTask.result;
    uint64_t fileSize = [[[NSFileManager defaultManager] attributesOfItemAtPath:uploadPart.uploadPartFileURL.absoluteString error:nil] fileSize];
    [partInfos addObject:[OSSPartInfo partInfoWithPartNum:i eTag:result.eTag size:fileSize]];
            } else {
    NSLog(@"upload part error: %@", uploadPartTask.error);
    NSLog(@"uploadObjectkey = %@", uploadObjectkey);
            }
            
            return nil;
        }];



以下是串行的核心代码：


uploadPart.uploadPartData = tempPartData;
        OSSTask * uploadPartTask = [self.ossClient uploadPart:uploadPart];
        [uploadPartTask waitUntilFinished]; ///< 串行操作
        if (!uploadPartTask.error) {
    OSSUploadPartResult * result = uploadPartTask.result;
    uint64_t fileSize = [[[NSFileManager defaultManager] attributesOfItemAtPath:uploadPart.uploadPartFileURL.absoluteString error:nil] fileSize];
    [partInfos addObject:[OSSPartInfo partInfoWithPartNum:i eTag:result.eTag size:fileSize]];
        } else {
    NSLog(@"upload part error: %@", uploadPartTask.error);
    NSLog(@"uploadObjectkey = %@", uploadObjectkey);
        }
