Objective-C将main.m转换成main.cpp

本文是文章OC的本质中嵌入的代码
转换方法：
xcrun -sdk iphoneos clang -arch arm64 -rewrite-objc main.m -o main.cpp

// 转换的代码main.m
int main(int argc, const char * argv[]) {
    @autoreleasepool {
        NSObject *obj = [[NSObject alloc] init];
    }
}

// 转成后的代码main.cpp 一共31634行，但是由于过长保存不了，只摘取了前边的千八百行
