Ios AWS SDK S3上传Credentails

我遵循AWS的本教程（）使用swift和xcode设置AWS sdk iOS 9应用程序。我正在尝试将文件上载到S3存储桶

我在AppDelegate.swift文件中添加了以下代码 //初始化Amazon Cognito凭据提供程序

let credentialsProvider = AWSCognitoCredentialsProvider(regionType:.USEast1,identityPoolId:"mypoolid")

let configuration = AWSServiceConfiguration(region:.USEast1, credentialsProvider:credentialsProvider)

AWSServiceManager.defaultServiceManager().defaultServiceConfiguration = configuration

我还将代码片段包含在Info.plist文件中

<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
    <key>amazonaws.com</key>
    <dict>
          <key>NSThirdPartyExceptionMinimumTLSVersion</key>
          <string>TLSv1.0</string>
          <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
          <false/>
          <key>NSIncludesSubdomains</key>
          <true/>
    </dict>
    <key>amazonaws.com.cn</key>
    <dict>
          <key>NSThirdPartyExceptionMinimumTLSVersion</key>
          <string>TLSv1.0</string>
          <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
          <false/>
          <key>NSIncludesSubdomains</key>
          <true/>
    </dict>
</dict>

我的问题是文件没有上传到S3 bucket…凭据设置中有错误…在serviceConfiguration中，创建bucket的区域不正确…一旦我更改了文件的上传位置。

您没有通过

Info.plist

提供配置。相反，您使用的是

defaultServiceConfiguration

。您可以安全地忽略此消息。很抱歉回答得很简短，由于代表率低，我无法发表评论。我不确定这是否是您的情况，但在我的应用程序中设置身份池时，我缺少该区域。应用程序代理中的identityPoolId也应包括它。请尝试：让credentialsProvider=AWSCOgnitoRedentialsProvider（regionType:AWSRegionType.USEast1，identityPoolId:“us-east-1:xxxxxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxx”）发表您的评论…我只是以键入“mypoolid”为例

Couldn't read credentials provider configurations from `Info.plist`. 
Please check your `Info.plist` if you are providing the SDK configuration values through `Info.plist`.
