iOS

Question

所有aws-sdk-ios示例使用AWSS3TransferManager上传数据异步.

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，但由于其他原因我的工作已经在 NSOperation 子类中，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，并且有更多的样板...）

有人知道怎么做吗？

如果有人好奇，我想通了：

    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()

...是的。我找不到示例 anywhere，所以我不得不阅读源代码并找出答案。至于那个 aws-sdk-ios 库，谈论过度工程......花了一些时间通过所有这些间接层来弄清楚它。

无论如何，在我 return nil 的最后一个块中，您将在那里处理错误等
