我在 openglES 项目中使用 xcode4，我从教程中添加了用于应用内购买的代码： http ://www.raywenderlich.com/2797/introduction-to-in-app-purchases

我添加了 SystemConfiguration.framework 但发生此错误：

如果我删除框架引用，错误是一样的。再次添加没有任何反应......在 -Xlinker 2 -framework Foundation -framework UIKit [...] 我应该看到“-framework SystemConfiguration”吗？为什么不存在？有人有想法吗？

从项目中提取框架->构建阶段->将二进制文件与库链接，使其成为我遇到此错误的第一个框架：

SystemConfiguration 在那里，错误仍然在那里......它可能是什么？谢谢

找到了！我已将 SystemConfiguration.framework 复制到我的项目文件夹中（当我从 xcode 添加时选中该框）。在我的项目中删除该文件夹现在编译得很好

SystemConfiguration.framework从构建阶段添加后，我的项目编译良好......

玩得开心...！

我也有同样的问题。我直接通过拖放添加了一些框架。

为了解决这个问题，我删除了所有这些并通过菜单Target>Build Phases添加它们，然后再次通过Link Binary With Libraries添加所有需要的框架。

在此之后，您的代码应该可以再次正常工作。

这很简单。

scnetworkreachability回调被标记为未定义的符号，这意味着缺少某些库或框架文件

前缀sc表示系统配置

  • 单击项目名称选择右侧的摘要

  • 单击链接二进制文件和框架

  • 单击加号，然后您可以看到包含框架和库集合的下钻，看看是否有任何称为 systemConfigurationframework

  • 选择它并按确定

  • 现在编译运行问题就解决了

如上所述，导入以下3个框架后，就可以了！

    CFNetwork.framework
    Security.framework
    SystemConfiguration.framework

非常感谢！

从 repo 更新后我遇到了同样的问题。

对我有用的解决方案是从项目中删除所有类的引用并再次添加它们。问题是很有可能会搞乱 repo 同步。

我想指出我也遇到了与此类似的问题。

我将一些文件复制到 xcode 并意外选择了“ProjectTests”而不是项目。只需删除文件并将它们重新添加到您的项目中，确保选择主项目（而不是单元测试）
