UITableViewCell 添加长按手势（别的手势类似）

UILongPressGestureRecognizer *longPressGR = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressAction:)];
[_tableView addGestureRecognizer:longPressGR];

- (void)longPressAction:(UILongPressGestureRecognizer *)longPressGR
{
    if (longPressGR.state == UIGestureRecognizerStateBegan) {
        
        CGPoint point = [longPressGR locationInView:_tableView];
        NSIndexPath *indexPath = [_tableView indexPathForRowAtPoint:point];
        NPTaskCell *cell = [_tableView cellForRowAtIndexPath:indexPath];
       // do some thing in here
    }
}
