iOS - 同步上传到AWS S3

Question

所有aws-sdk-ios示例都使用异步AWSS3TransferManager上传数据.

例如:https://github.com/awslabs/aws-sdk-ios-samples/blob/master/S3TransferManager-Sample/Swift/S3TransferManagerSampleSwift/UploadViewController.swift#L81

现在通常,这很好,但是NSOperation由于其他原因,我的工作已经在子类中了,所以我想同步上传到S3以保持简单(否则,我需要实现异步NSOperation,这有很多更多样板......)

有人知道怎么做吗？

如果有人好奇,我想出来:

    let credentialsProvider = AWSCognitoCredentialsProvider(regionType: AWSRegionType.USEast1,
                                                            identityPoolId: AwsCognitoIdentityPoolId)
    let configuration = AWSServiceConfiguration(region: AWSRegionType.USEast1,
                                                credentialsProvider: credentialsProvider)
    AWSServiceManager.defaultServiceManager().defaultServiceConfiguration = configuration

    let S3Client = AWSS3.defaultS3()
    let putObjectRequest = AWSS3PutObjectRequest()
    putObjectRequest.bucket = AwsBucketName
    putObjectRequest.key = key
    putObjectRequest.body = logFilePathURL

    do {
        let fileAttributes = try self.fileManager.attributesOfItemAtPath(logFilePathURL.path!)
        let fileSizeNumber = fileAttributes[NSFileSize] as! NSNumber
        putObjectRequest.contentLength = NSNumber(longLong: fileSizeNumber.longLongValue)
    } catch _ as NSError {
        // TODO handle error
    }

    S3Client.putObject(putObjectRequest).continueWithBlock { (task: AWSTask) -> AnyObject? in
        return nil
    }.waitUntilFinished()

...是啊.我无法在任何地方找到一个例子,所以我必须阅读源代码并解决问题.至于那个aws-sdk-ios图书馆,谈论过度工程......需要一段时间才能通过所有这些间接层来弄明白.

无论如何,在那个我return nil处理错误的最后一块,等等.
