UILongPressGestureRecognizer not works with tableview

I had added a UILongPressGestureRecognizer to a tableview in my ViewDidLoad method. I added this to detect long press on table view in my code. But it never works. In ViewDidLoad I added this code :

UILongPressGestureRecognizer *lpgr = [[UILongPressGestureRecognizer alloc] 
                                      initWithTarget:self action:@selector(handleLongPress:)];
lpgr.minimumPressDuration = 2.0; //seconds
lpgr.delegate = self;
[self.resultTableView addGestureRecognizer:lpgr];
[lpgr release];

I also added this method : 

-(void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{
    CGPoint p = [gestureRecognizer locationInView:self.resultTableView];

    NSIndexPath *indexPath = [self.resultTableView indexPathForRowAtPoint:p];
    if (indexPath == nil) {

        NSLog(@"long press on table view but not on a row");
    }
    else {


        NSLog(@"long press on table view at row %d", indexPath.row);
    }


}

Please help me to resolve this?

If the gesture recognizer is being blocked by the UITableView panGestureRecognizer, implement the delegate to ensure both can work

 -(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

Your code is working. I think you have to add UIGestureRecognizerDelegate delegate in .h file or how to declare resultTableView i mean you define programmatically or using .xib file.Check it once.

I have tried like this.

     resultTableView = [[UITableView alloc] init];
     resultTableView =[[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320, 420) style:UITableViewStylePlain];
    resultTableView.rowHeight = 100.0;
    resultTableView.delegate=self;
     resultTableView.dataSource=self;
    [self.view addSubview:resultTableView];

    UILongPressGestureRecognizer *lpgr = [[UILongPressGestureRecognizer alloc] 
                                          initWithTarget:self action:@selector(handleLongPress:)];
    lpgr.minimumPressDuration = 2.0; //seconds
    lpgr.delegate = self;
    [resultTableView addGestureRecognizer:lpgr];
    [lpgr release];

It looks like you want to add the gesture to the individual cells, but you are adding the gesture to the table. Try adding the gesture to your UITableViewCell instead.
