错误日志就像当我用下面的 liblib.a

 文件是专为存档而不是被连接的架构（ARMv7的）：/Users/apk/Desktop/libTest/liblib.a
适用于建筑的ARMv7未定义的符号：
 

看来 liblib.a 为不支持的ARMv7 ，但我没有找到的ARMv7和arm64在构建设置 - >架构

I trying to build C library for iOS like the following picture.

I have build the liblib.a , but it compile error after I use liblib.a

The error log is like the following when I use liblib.a

file was built for archive which is not the architecture being linked (armv7): /Users/apk/Desktop/libTest/liblib.a
Undefined symbols for architecture armv7:

It seems the liblib.a not support for armv7, but I didn't find the armv7 and the arm64 in Build Setting -> Architectures.

How do I build the library of C code for armv7 and use in Objective-C ?

---------------------EDIT---------------------

After I change the setting like the following picture.

It has the .a file. But when I try to use this library , it also show

file was built for archive which is not the architecture being linked (armv7): /Users/apk/Desktop/libTest/liblib.a
