Please help

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];
}
