ios开发中遇到的错误总结

开始做个记录,逐渐添加~

 

1:Undefined symbols for architecture arm64:

 

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_FBSession", referenced from: someFile
ld: symbol(s) not found for architecture arm64

解决:

 

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

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:

enter image description here

  • Now go to the AppName-Info.plist file, and look for the key “Require device capabilities” and delete it all.
