Question

I want to access the UITableViewCell that is after the one that is selected and select that one,

int b = lastIndexPath.row + 1;   //lastIndexPath references to the current selected cell index path

NSIndexPath *myNextIndex = [[NSIndexPath alloc]initWithIndex:b];

[self tableView:table didSelectRowAtIndexPath:myNextIndex];

so up to this point everything works fine, the b value is 2. but when the tableView:didSelectRowAtIndexPath: and I want to get the value of i,

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

int i = indexPath.row;

//some other stuff

}

I get the value 81809923 for i, but the value of i should be 2.

I don’t know why this would happen. if anyone has any idea please help.

thanks

Positions in a UITablleView are keyed by both section and row (even if your table only has a single section). The iOS SDK adds a utility method specifically for the purpose of making it easier to work with table views.

In this case, you would use it like:

NSIndexPath* myNextIndex = [NSIndexPath indexPathForRow:b inSection:0];  //call 'retain' if you need to

As for your 81809923 value, that is probably random garbage that happened to be in memory, since your original code does not assign any value to the row field of the NSIndexPath.
