Xcode 5.1 ld: 找不到-lGoogleAnalyticsServices库

Question

今天我把Xcode升级到了Xcode 5.1版本，现在每次尝试在模拟器上编译并测试我的代码时，都会遇到关于体系结构86_64和Google Analytics Services Library的几个错误。

以下是我遇到的错误内容：

我也更新了Google Analytics库，尝试删除并重新添加它，但没有效果。

我下载了一个新版本3.03c，进行了清理和构建，一切都恢复正常了。我猜你的旧库（就像我的一样）不支持这些架构。这是URL https://developers.google.com/analytics/devguides/collection/ios/resources - DBD

我已经尝试过了，我删除了所有的.m和.h以及框架文件...然后重新添加了3.03c的所有文件，进行了一次清理，但是什么也没有改变...也许问题出在“构建设置”上...你在“搜索路径”和“有效架构”上设置了什么？ - prelite

将目标更改为ïOSDevice解决了我的问题。对于模拟器，它不起作用。奇怪。 - Nirav

解决方案：我只需添加 libz.dylib 框架，一切都正常工作了！

谢谢。这节省了我很多时间。V3不向后兼容真的很烦人。而且新方法需要更多的编码才能完成与之前版本相同的事情。请接受您自己的答案作为正确答案。 - Ray

如果您加载 .xcodeproj 文件并尝试构建，则会出现此错误。 相反，请打开包含的 .xcworkspace，然后一切都会很好。

要么选择“打开其他”并从您的项目目录中选择它，要么从项目目录中的命令提示符：

open <YourProjectName>.xcworkspace

不应该需要其他依赖项。
