How to expand cell of a Table View with animation... :)

here is how i am managing this

1. you need an NSMutableArray

the NSMutablearray is the same count as the datasource array for the table

so, you need to populate it with something like this


self.cellAccessArray = [[NSMutableArray alloc] initWithObjects:@"closed",@"closed",@"closed",@"closed",nil];
[self.cellAccessArray release];

this means we have 4 table rows

now, in your heightForRowAtIndexPath, put this


if([[self.cellAccessArray object atIndex:indexPath.row] isEqualToString:@"open"])
return 140;
return 70;

now, to the didSelectRowAtIndexPath

put this


if([[self.cellAccessArray objectAtIndex:indexPath.row] isEqualToString:@"closed"])
[self.cellAccesArray replaceObjectAtIndex:indexPath.row withObject:@"open"];
[self.cellAccesArray replaceObjectAtIndex:indexPath.row withObject:@"closed"];

[tableView reloadRowsAtIndexPath:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationNone];
