UITableView don't react on a tap

Question

I have a fully working grouped tableview. But when i just tap on a cell - nothing happens. willSelectRowAtIndexPath is not even being called. All outlets are set correctly, userInteractions are enabled, tableView is the only view on a page. Googling for hours made no success. Everyone has a selection feature from the begining and someone even tries to ged rid of it. Help, please.

Code (bad one, i know):

Answer 1

Did you implement something like this in your UITableView delegate?

- (BOOL)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    return NO;
}

Sorry, wrong assumption and a compiler warning ignored...

This is not the solution.

Answer 2

I did some experiments and found the property isUserInteractionEnabled on the UITableView View ancestor. If set to NO, the cell selection is disabled (as is any other interaction). In this case it is impossible to move the views cells up and down.
