使用pod安装MWPhotoBrowser错误

Question

当我运行我的项目时，那将是这样的错误：

ld: warning: directory not found for option '-L/Users/Andou/Desktop/JobProject/yundoumiao/yundoumiaoRV2/yundoumiaoRV2/Pods/build/Debug-iphoneos'
Undefined symbols for architecture armv7:
  "_OBJC_CLASS_$_MWPhoto", referenced from:
      objc-class-ref in YDMediaManager.o
  "_OBJC_CLASS_$_MWPhotoBrowser", referenced from:
      objc-class-ref in DetailViewController.o
      objc-class-ref in PhotoViewController.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我怎么能解决这个问题。请告诉我。谢谢你的帮助。
