Ios xcode抱怨在包含armv7体系结构的框架中不支持armv7体系结构

我正在构建一个iOS应用程序。链接框架时，我收到以下警告和错误：

ld: warning: ignoring file /Users/XXX/libs/abc.framework/abc, file was built for unsupported file format ( 0x56 0x65 0x72 0x73 0x69 0x6F 0x6E 0x73 0x2F 0x41 0x2F 0x69 0x43 0x6F 0x6E 0x6E ) which is not the architecture being linked (armv7): /Users/XXX/libs/abc.framework/abc

[ERROR] :  ** BUILD FAILED **
[ERROR] :  The following build commands failed:
[ERROR] :   Ld build/Debug-iphoneos/MyApp.app/MyApp normal armv7

当我在abc.framework文件（abc.framework/Versions/A/abc.1.0.1）中的库上运行lipo-info和file时，我看到这样一句话，它包含armv7体系结构：

lipo -info abc.1.0.1
Architectures in the fat file: abc.1.0.1 are: armv7 armv7s arm64 x86_64 

file abc.1.0.1
abc.1.0.1: Mach-O universal binary with 4 architectures
abc.1.0.1 (for architecture armv7): current ar archive random library
abc.1.0.1 (for architecture armv7s):    current ar archive random library
abc.1.0.1 (for architecture cputype (16777228) cpusubtype (0)): current ar archive random library
abc.1.0.1 (for architecture x86_64):    current ar archive random library

所以我无法链接。我花了一整天的时间尝试了所有的事情。为什么它会抱怨在armv7架构中找不到它？另外，有人能解释一下这是什么不受支持的文件格式吗？

这可能会有帮助：
