clang -rewrite-objc: 将OC代码转成 C/C++
1. 最基本的
clang -rewrite-objc main.m
2.指定真机:
xcrun -sdk iphoneos clang -rewrite-objc main.m
指定模拟器:
xcrun -sdk iphonesimulator clang -rewrite-objc main.m
指定特定版本的SDK
xcrun -sdk iphonesimulator11.3 clang -rewrite-objc main.m
NOTE: 使用 xcodebuild -showsdks 可以查看系统的SDK。
clang ❯ xcodebuild -showsdks
