How can I scroll the table's cell to specific position ? I have a table which shows 3 rows (according to height). what I want is if I click on 1st row than according to table's height the 1st row should scroll and get new position (center) and same for other rows. I tried contenOffset but did not work..

EDITED :

In short some thing like data picker when we select any row in picker the row scrolls to the center.

Thanks..

it should work using - (void)scrollToRowAtIndexPath:(NSIndexPath *)indexPath atScrollPosition:(UITableViewScrollPosition)scrollPosition animated:(BOOL)animated using it this way:

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[yourTableView scrollToRowAtIndexPath:indexPath 
                     atScrollPosition:UITableViewScrollPositionTop 
                             animated:YES];

atScrollPosition could take any of these values:

typedef enum {
UITableViewScrollPositionNone,
UITableViewScrollPositionTop,
UITableViewScrollPositionMiddle,
UITableViewScrollPositionBottom
} UITableViewScrollPosition;

I hope this helps you

Cheers
