如何使用AWSS3 TransferManager上传请求上传图像目标c？

Question

我是亚马逊sdk的新手，我想上传图片，我使用的代码是亚马逊的代码，我需要在正文中输入上传图片？：

AWSS3TransferManager *transferManager = [AWSS3TransferManager defaultS3TransferManager];

AWSS3TransferManagerUploadRequest *request = [[AWSS3TransferManagerUploadRequest alloc] init];
request.bucket = kBucket;
request.key = fileName;
request.body =url;
request.contentType = @"image/jpeg";


[[transferManager upload:request] continueWithExecutor:[BFExecutor mainThreadExecutor]
                                                   withBlock:^id(BFTask *task) {
                                                       NSLog(@"ckmdkcd dvdsv");
                                                       if (task.error) {
                                                           if ([task.error.domain isEqualToString:AWSS3TransferManagerErrorDomain]) {
                                                               switch (task.error.code) {
                                                                   case AWSS3TransferManagerErrorCancelled:
                                                                   case AWSS3TransferManagerErrorPaused:
                                                                       break;

                                                                   default:
                                                                       NSLog(@"Error: %@", task.error);
                                                                       break;
                                                               }
                                                           } else {
                                                               // Unknown error.
                                                               NSLog(@"Error: %@", task.error);
                                                           }
                                                       }

                                                       if (task.result) {
                                                           AWSS3TransferManagerUploadOutput *uploadOutput = task.result;
                                                           // The file uploaded successfully.
                                                       }
                                                       return nil;
                                                   }];

request.body应根据设备上存储的文件设置为NSURL。您可以使用NSFileManager将UIImage保存到磁盘（文档或缓存）。
