Question

我正在为iPhone开发一款应用程序，并集成了Amazon SDK v 2.0.10来执行文件传输。

当我尝试集成最新的SDK v，即2.0.13时，我收到以下错误。请帮帮我。

此错误消息表示在链接时在多个框架/目标中找到了具有相同名称的类。

在这种情况下，它主要抱怨Bolts框架中的类在主AWSiOSSDKv2.framework和Bolts.framework中找到。

我刚刚下载了适用于iOS的亚马逊SDK from here并对其进行了反编译，似乎确实包含了螺栓类（事实上，快速浏览似乎有其他三分之一的大多数类主AWS SDK中的派对框架。

这反对他们所说的integration documentation here

按照相同的步骤，将位于第三方目录中的以下框架添加到项目中。

这是亚马逊如何构建和分发SDK的错误。

目前您有两种可能的解决方法：

从项目中删除third-party文件夹中的框架。它应该都是Just Work™
按照上面指南中的说明使用Cocoapods安装AWS开发工具包。

我建议您联系亚马逊，以便为将来的用户报告此问题。

亚马逊最新SDK与iOS集成会出错
