Answer 1

When user selects any category then in didSelectRowAtIndexPath you can initialize your typeArray based on category selected:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if(tableView == tblSimpleTableType)
{
//initialize typeArray;
//Once typeArray is initialized just reload the tableview as follows:
[tblSimpleTableType reloadData];
}
}

Just try by returning the cell at last of the function only and see.
