The problem, which you are facing because you are always using the last like button.

You require to make few changes, Append an in the function name like likeComment:.

    [like addTarget:self action:@selector(likeComment:) forControlEvents:UIControlEventTouchUpInside];

And modify your likeComment method like below.

- (void )likeComment:(id) sender {

        UIButton* myLikeButton = (UIButton*)sender;
        NSString *idStr = [NSString stringWithFormat:@"%@/likes",[[facebook commentId]objectAtIndex:myLikeButton.tag]];



        [fbGraph doGraphPost:idStr withPostVars:nil];   

        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"You like this"
                                                       message:@"" delegate:nil
                                             cancelButtonTitle:@"Ok" otherButtonTitles:nil ];

        [alert show];
        [alert release];
}
