Xcode_ library not found for -lAFNetworking

1.错误现象：

ld: library not found for -lAFNetworking
clang: error: linker command failed with exit code 1 (use -v to see invocation)

2.当Linked Frameworks and Libraries 中加入“libPods-XXX.a”后报错“Apple Mach-O Linker Error”

解决：
1.首先先选中工程中的Pods 工程 targets -> 选中框架（比如AFNetworking）->Build Setting ->Architectures -> Build Active Architecture Only ->Debug设置为YES，Release设置为NO（默认都是这么设置的）
