I would set Architecturesin your project to $(ARCHS_STANDARD_32_BIT), which will do the right thing for both iOS builds and OS X / simulator builds.
我将Architectures在您的项目中设置为$(ARCHS_STANDARD_32_BIT)，这将对 iOS 构建和 OS X / 模拟器构建做正确的事情。
The problem is that your library is not built for x86_64, but your project is trying to build for both i386 and x86_64, so the link step fails. Apple changed the default architecture in Xcode 5.1 to include 64-bit architectures.
问题是您的库不是为 x86_64 构建的，但是您的项目正在尝试为 i386 和 x86_64 构建，因此链接步骤失败。Apple 更改了 Xcode 5.1 中的默认架构以包含 64 位架构。

Click on your project in xcode and go to build settings -> valid architectures and remove arm64also change Standard Architecturesto armv7 and armv7s .Clean and rerun the project
在 xcode 中单击您的项目并转到构建设置 -> 有效架构并删除对 armv7 和 armv7s 的arm64更改Standard Architectures。清理并重新运行项目

It looks like you need to include the Salesforce Mobile SDK iOS framework in your project.
看起来您需要在您的项目中包含 Salesforce Mobile SDK iOS 框架。
