为什么编译会出现这样
TUSMtekiMacBook-Pro-2:q tusm$ cc 01-cc.m framework Foundation
clang: error: no such file or directory: 'framework'
clang: error: no such file or directory: 'Foundation'

帮顶，等大神出现。。。。。

你的main主函数都写错了

还有就是你的set和get方法都没有写的吧，如果是按照你上面的格式写的话set和get方法应该是要写的

第一行调用框架不是用@，应该是#import <Foundation/Foundation.h>

cc 01-cc.m  -framework Foundation

@import<Foundation/Foundation.h>  // 改为 #import <Foundation/Foundation.h>
@interface CCar : NSObject
{
    @public
    int speed;
   
    int wheel;
}
-(void) run;
@end

@implementation CCar
-(void) run
{
    NSLog(@"速度为%d,轮子个数为%d",speed,wheel);
}
@end

int mian()   // 改为 int main()
{
    CCar *p = [CCar new];
    p->speed = 100;
    p->wheel = 3;
    [p run];
    return 0;
}
