Undefined symbols for architectu

在pod install  AVOSCloud 框架后，编译运行报一下错误：

Undefined symbols for architecture arm64:

"_OBJC_CLASS_$_AVAnalytics", referenced from:

objc-class-ref in AppDelegate.o

"_OBJC_CLASS_$_AVOSCloud", referenced from:

objc-class-ref in AppDelegate.o

ld: symbol(s) not found for architecture arm64

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

原因是程序没找到pod 进来的框架，需要设置路径：最后参考

方便复制：$(inherited)
