clang -rewrite-objc main.m 报错:
****fatal error: ****'UIKit/UIKit.h' file not found**
解决:
clang -x objective-c -rewrite-objc -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk xxxxx.m
简便做法,配置 alias
vim ~/.bash_profile
alias runtimeoc='clang -x objective-c -rewrite-objc -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk'
保存退出
执行source ~/.bash_profile(这句一定要执行,执行才会生效)
zsh配置,同上
open ~/.zshrc
alias runtimeoc='clang -x objective-c -rewrite-objc -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk'
保存退出
执行source ~/.zshrc (这句一定要执行,执行才会生效)
执行完之后,会在目录下生成一个 xxx.cpp文件,打开查看就是runtime运行时代码。
