ios 真机调试遇到的错误： ld: symbol(s) not found for architecture arm64的解决办法

错误信息如下：

Undefined symbols for architecture armv7s:

  "_OBJC_CLASS_$_BaiduMobStat", referenced from:

      objc-class-ref in BaiduMobStatAppDelegate.o

      objc-class-ref in MyPageLogViewController.o

     (maybe you meant: _OBJC_CLASS_$_BaiduMobStatAppDelegate)

ld: symbol(s) not found for architecture armv7s

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

报此错误是因为你选的SDK不支持armv7s，在Bulid Settings 中Valid Architectures 中把armv7s删除就行了

现在Xcode已经升级到5.1了，如果用6.1SDK就会报ld: symbol(s) not found for architecture arm64的错误，这个目前比较常见，按以上的办法就可以解决了

希望可以帮到大家
