Question

从iOS 11.4.1设备上将文件上传到AWS S3存储桶（使用AWS-IOS-SDK-2.6.24）时遇到问题。相同的代码适用于iOS 9.x.x。

主要是我收到超时错误：

我正在关注AWS文档，仅从AWS文档中收集了所有必需的详细信息。

我已经配置了 info.plist ，并且还将 awrconfiguration.json 添加到了我的项目中。

我已经在我的AppDelegate类中提到了凭据：

AWSCognitoCredentialsProvider *credentialsProvider = [[AWSCognitoCredentialsProvider alloc]
                                                          initWithRegionType:AWSRegionAPSouth1
                                                          identityPoolId:@"ap-south-1:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx”];


    AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionAPSouth1
                                                                         credentialsProvider:credentialsProvider];
    [AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;

我无法理解我在这里做错了什么，因为代码在旧版iOS中可以正常工作。

我的另一个问题是：如果我们确实需要在AppDelegate类中提供凭据，那么为什么我们需要配置info.plist或为什么需要将awsconfiguration.json文件复制到我们的项目中。在不定义AppDelegate.m文件中的凭据的情况下，以什么方式从info.plist读取凭据或以编程方式读取awsconfiguration文件的方法是什么？

Answer 1

这是部分答案。

嗨，

首先，消除混乱。您只需要一个：

awsconfiguration.json
Info.plist
基于代码的凭据 AppDelegate（或其他地方）

第二，要从awsconfiguration.json-或-Info.plist访问配置，您可以构造：

AWSS3TransferUtility *transferUtility = [AWSS3TransferUtility defaultS3TransferUtility];

在我进一步调试时，您能否仅尝试基于代码的方法并在此处回复？

无法通过iOS 11.4.1将文件上传到S3存储桶（AWS-IOS-SDK-2.6.24）
