ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

解决方案:

Xcode升级到6.1.1 默认让所有App都通过64位编译器编译。原来在Xcode6.0的时候默认的Architectures只有(arm7,armv7s),到6.1.1默认就带上arm64的参数了。

1.把1.选中Targets—>Build Settings—>Architectures。

把build active architectures only 改为 NO。

2. 把最下面的Valid Architectures中的arm64参数删掉就可以了

   或者:

双击Architectures,选择other,删除$(ARCH_STANDARD),然后增加armv7和armv7s(写上:$(ARCHS_STANDARD_32_BIT))。

3.clean 再build。

结果设置如下图:
