我已经构建了liblib.a,但在使用liblib.a后它编译错误

当我使用liblib.a时,错误日志如下所示

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

似乎liblib.a不支持armv7,但我没有在Build Setting中找到armv7和arm64 – >架构.

如何为armv7构建C代码库并在Objective-C中使用？

– – – – – – – – – – -编辑 – – – – – – – – – – –

我改变设置后,如下图所示.

它有.a文件.但是当我尝试使用这个库时,它也会显示出来

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

我错过了什么吗？

1.创建新项目.

2.设置
