你必须使用 Objective-C Runtime functions自己动手.这是一些非常基本的示例代码.请注意,获取类的ivars不会获得其超类的ivars.您需要明确地执行此操作,但函数都在运行时中.

#import <objc/objc-runtime.h>
#include <inttypes.h>
#include <Foundation/Foundation.h>

@interface Foo : NSObject
{
    int i1;
}
@end
@implementation Foo
@end

@interface Bar : Foo
{
    NSString* s1;
}

@end
@implementation Bar
@end

int main(int argc,char** argv)
{
    NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init];

    unsigned int count;
    Ivar* ivars = class_copyIvarList([Bar class],&count);
    for(unsigned int i = 0; i < count; ++i)
    {
        NSLog(@"%@::%s",[Bar class],ivar_getName(ivars[i]));
    }
    free(ivars);


    [pool release];
}
