Iphone xcode 4.5：架构armv7s的未定义符号：

我完全为那个问题发疯了。。 我有一个工作正常的项目，但在我添加了facebook sdk之后，它给了我以下错误（这些错误使我删除了armv6，希望它在之后可以正常工作，但在我处理它时，它给了我更多的问题。）。。 我现在同时使用ArchArmV7和armv7，这就是它给出的错误

Facebook sdk不是为ARMV7编译的，但您可以自己编译

看看利亚姆·尼科尔斯的回答

从git hub页面（）下载源代码副本 打开xcode项目，在构建设置中将架构更改为armv7、armv7s 关闭项目 导航到/scripts并在终端运行

/build\u all.sh

---

编译完成后，您可以在builds/FacebookSDK.framework中找到该框架。作为一个临时解决方案，您可以从Xcode项目的体系结构中删除armv7。将“$（ARCHS_标准_32_位）”更改为“armv7”。更新库后，将更改回重新添加armv7s支持。

从

有效体系结构

部分删除

armv7s

，它将正常工作

生成设置-->体系结构-->有效体系结构

您似乎使用了一个预编译的静态库，其中不包含armv7s片段。您粘贴的文本不包含错误，您应该给我们正确的输出。抱歉，我已经编辑它以显示错误OK，所以它是Facebook SDK。您使用编译库（类似于Facebook.a）吗，或直接使用FB SDK源文件？如果使用源文件，则应重新清理和生成项目。如果不使用，则应使用源文件。我使用的是FacebookSDK.framework，我创建了一个干净的生成文件夹，但没有发生任何事。我添加了（account.framework）所有的facebook错误都消失了。现在我有admob和revmob的问题。现在怎么办？
