ios开发中遇到的编译错误总结

1：Undefined symbols for architecture arm64:

project -> target (your project name) -> build settings and change architectures to standard architectures (armv7, armv7s), and valid architectures to armv7, armv7s.

参考：http://stackoverflow.com/questions/19213782/undefined-symbols-for-architecture-arm64

2：No architectures to compile for (ARCHS=arm6 arm7, VALID_ARCHS=armv7)

解决：

• Go to Project Target > Build Settings > Architectures Delete whatever you see there, and then add these rows one by one:

  armv6 armv7

  There are no ‘save‘ buttons there, so what I do, is adding another blank row, pressing enter, removing it, and then clicking out somewhere else, so that I make sure I have both of them added:

  

  • Now go to the AppName-Info.plist file, and look for the key "Require device capabilities" and delete it all. 参考：http://stackoverflow.com/questions/10005896/no-architectures-to-compile-for-archs-arm6-arm7-valid-archs-armv7
