iOS静态库Xcode(链接错误) [英] iOS Static Library Xcode (linking errors)

问题描述

我使用编译选择设备的Xcode创建了静态库.

I created a static library with Xcode I have compiled selecting a device.

我将此添加到了Xcode 4.6的库测试项目中

I added this to my library test project in Xcode 4.6

但是在链接过程中我总是有2个错误...

but I always have 2 errors during the linking...

我遵循了本教程:静态库iOS教程

如果我下载示例代码，我将遇到相同的错误:

if I download the sample code I have the same errors:

ld:警告:忽略文件/Users/Downloads/ICodeBlogStaticLibrarySample/MathTest/Classes/ICodeBlogsMathTest/Classes/ICodeBlogStaticLibrarySample/MathTest/Classes/iCodeBlogsMathLibrary/libICodeMathUtils.a，缺少必需的体系结构i386.片)体系结构i386的未定义符号:"_OBJC_CLASS _ $ _ MathFunctions"，引用自:MathTestAppDelegate.o中的objc-class-refld:找不到体系结构i386的符号clang:错误:链接器命令失败，退出代码为1(使用-v查看调用)
