问题描述
有与我要问的问题类似的问题，但它们针对的是在模拟器上运行，而不是在实际设备上运行。 当我尝试在我的设备上构建和运行我的应用程序时，我收到错误
Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_GMSPlacesClient",referenced from:
objc-class-ref in BackendEngine.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command Failed with exit code 1 (use -v to see invocation)
谷歌将 sdk for iOS Getting Started Page 指定使用源并定位到 pod，我已将其包含在我的 Podfile 中，如下所示：
target 'TestApp' do
use_frameworks!
#source 'https://github.com/CocoaPods/Specs.git'
source 'https://cdn.cocoapods.org/'
pod 'GooglePlaces','4.2.0'
end
规范 GitHub 链接不用作源，因为每当我尝试运行它时，它都会明显挂起并在某些命令上被阻止（如果我输入键盘中断，我总是会得到相同的回溯：
>cloning spec repo `cocoapods` from `https://github.com/CocoaPods/Specs.git`
$ /usr/bin/git clone https://github.com/CocoaPods/Specs.git -- cocoapods
cloning into 'cocoapods'...

我是 Pod 的新手，任何帮助将不胜感激！
解决方法
- 你的pod安装成功了吗？
- 我 pod
GooglePlaces并成功，并运行成功
我最终解决了它！发生的事情是在我的应用程序中，我的链接器标志缺少 GooglePlaces 和 GoogleMaps 依赖项的框架。我只是加了
-framework "GoogleMapsBase" -framework "GooglePlaces"
到构建设置中的“其他链接器标志”选项。使用原始问题中描述的 pod 文件效果很好。
