问题
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
Undefined symbols for architecture armv7:

1.Create new project.
2.Setting
3.
4.
5.put the C file and the .h file into project.
