适用于iOS的Google iOS DFP和Google Analytics不能协同工作

概述我正在开发一个iOS应用程序,我的客户请求实施DFP和Google Analytics. 实施广告横幅非常简单,但当我添加Google Analytics需要的库时,xcode会显示28个错误. 当我删除-ObjC链接器标志时,错误消失了,但这样DPF实现将无法工作. 这是错误,任何想法？ Undefined symbols for architecture x86_64: "_NSOverw 我正在开发一个iOS应用程序,我的客户请求实施DFP和Google Analytics.

实施广告横幅非常简单,但当我添加Google Analytics需要的库时,xcode会显示28个错误.

当我删除-ObjC链接器标志时,错误消失了,但这样DPF实现将无法工作.

这是错误,任何想法？

解决方法 尝试在项目中包含“libsqlite3.0dylib”,如建议的那样 here.查看是否遗漏了任何其他库或框架. 总结
