,char *argv[]) { @autoreleasepool{ Son *son = [[Son alloc] init]; [son fall_in_love_with:@"lili"]; [son think]; Baba *baba = [[Baba alloc] initWithSon:son]; [son fall_in_love_with:@"mimi"]; [son think]; //儿子本来喜欢的是libinbin，可是... [son fall_in_love_with:@"libinbin"]; //被他老爸用特异功能改成fanbinbin啦！ [son think]; } return 0; }
