1. 先分别看下两个的结构
0x01 framework
framework
0x02 xcframework
xcframework
2. 指令集
0x01 framework
➜ WebRTC.framework ls
Headers Info.plist LICENSE.md Modules WebRTC
➜ WebRTC.framework lipo -info WebRTC
Architectures in the fat file: WebRTC are: x86_64 i386 armv7 arm64
0x02 xcframework
➜ WebRTC.xcframework ls
Info.plist ios-arm64_armv7 ios-x86_64-simulator
➜ WebRTC.xcframework lipo -info ios-arm64_armv7/WebRTC.framework/WebRTC
Architectures in the fat file: ios-arm64_armv7/WebRTC.framework/WebRTC are: armv7 arm64
➜ WebRTC.xcframework lipo -info ios-x86_64-simulator/WebRTC.framework/WebRTC
Architectures in the fat file: ios-x86_64-simulator/WebRTC.framework/WebRTC are: x86_64
3. 把framework 转为xcframework
原理： 先把指令集拆分，再合成
1. 拆分指令集
# 先把framrwork 拷贝到两个文件夹下边
# 我这里只需要armv7 arm64 x86_64
mkdir iphoneos iphonesimulator
➜ combineSDKDir ls
WebRTC.framework iphoneos iphonesimulator
➜ combineSDKDir cp -R WebRTC.framework iphoneos
➜ combineSDKDir cp -R WebRTC.framework iphonesimulator
# 我们把 iphoneos 中的模拟器 指令集删除
➜ combineSDKDir lipo -remove i386 -remove x86_64 iphoneos/WebRTC.framework/WebRTC -o iphoneos/WebRTC.framework/WebRTC
➜ combineSDKDir lipo -info iphoneos/WebRTC.framework/WebRTC
Architectures in the fat file: iphoneos/WebRTC.framework/WebRTC are: armv7 arm64
# 再把 iphonesimulator 中的除模拟器之外的指令集删除
➜ combineSDKDir lipo -remove i386 -remove armv7 -remove arm64 iphonesimulator/WebRTC.framework/WebRTC -o iphonesimulator/WebRTC.framework/WebRTC
➜ combineSDKDir lipo -info iphonesimulator/WebRTC.framework/WebRTC
Architectures in the fat file: iphonesimulator/WebRTC.framework/WebRTC are: x86_64
2. 合成xcframework
# 使用xcodebuild 进行合成
➜ combineSDKDir xcodebuild -create-xcframework \
-framework iphoneos/WebRTC.framework \
-framework iphonesimulator/WebRTC.framework \
-output "WebRTC.xcframework"
xcframework successfully written out to: /Users/jr/Documents/temp/combineSDKDir/WebRTC.xcframework
3.这样子就生成好了
