体系结构i386的未定义符号:"_SCNetworkReachabilitySetCallback"

Question

我在openglES项目中使用xcode4,我已经从教程中添加了应用内购买代码:http://www.raywenderlich.com/2797/introduction-to-in-app-purchases

我添加了SystemConfiguration.framework但发生以下错误:

Ld /Users/Eros/Library/Developer/Xcode/DerivedData/blatest-acmdklrqungznggpjewgxuxqsvwo/Build/Products/Debug-iphonesimulator/blatest.app/blatest normal i386

如果我删除框架引用错误是相同的.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 - >使用库链接二进制文件使其成为第一个具有此错误的框架:

SystemConfiguration在那里,错误仍然存​​在......它可以是什么？谢谢

Answer 1

找到了!我已将SystemConfiguration.framework复制到我的项目文件夹中(当我从xcode添加时选中该复选框).删除我项目中的该文件夹现在编译得很好

Answer 2

SystemConfiguration.framework从构建阶段添加后,我的项目编译得很好......

玩得开心......!

Answer 3

我也有同样的问题.我直接添加了一些框架,拖放它们.

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,然后通过Link Binary With Libraries再次添加了所有需要的框架.

在此之后,您的代码应该再次正常工作.

Answer 4

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

• 单击加上它然后你可以看到向下钻取框架和库的集合,看看是否有任何名为systemConfigurationframework的东西

• 选择它,然后按确定

• 现在构建并运行问题就解决了

Answer 5

当我使用AFNetworking时,在获得这些错误后导入了3个框架

CFNetwork.framework
Security.framework
SystemConfiguration.framework

所有错误都将消失..享受!

Answer 6

如上所述,在导入以下3个框架后,它可以工作!

    CFNetwork.framework
    Security.framework
    SystemConfiguration.framework

非常感谢!
