ios - Google Analytics 不适用于新的 iOS 项目

Question

我已经创建了一个新的 iOS 项目并按照官方说明添加了 Google Analytics 支持。

我已经添加到框架中:

libGoogleAnalyticsServices.a
AdSupport.framework
CoreData.framework
SystemConfiguration.framework
libz.dylib

但它不适用于错误:

ld: warning: directory not found for option '-L/Users/.../Sources/GoogleAnalytics'
Undefined symbols for architecture armv7:
  "_OBJC_CLASS_$_NSManagedObjectModel", referenced from:
      objc-class-ref in libGoogleAnalyticsServices.a(GAICoreDataUtil.o)

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我该如何解决？它是否支持 arm64？

来自谷歌分析 developer page

The Google Analytics SDK uses the CoreData and SystemConfiguration frameworks, so you will need to add the following to your application target's linked libraries:

• libGoogleAnalyticsServices.a
• AdSupport.framework
• CoreData.framework
• SystemConfiguration.framework
• libz.dylib

看起来您遗漏了 CoreData.framework。

在 GA 库上运行 lipo -info 命令。

xcrun -sdk iphoneos lipo -info libGoogleAnalyticsServices.a

给出结果，

Architectures in the fat file: libGoogleAnalyticsServices.a are: armv7 armv7s i386 x86_64 arm64 

所以它确实支持arm64。

希望对您有所帮助!
