UITableView reload section

Question

I want to reload only one section not the full table. Is there any method in UITableView.

[tableView reloadData] is used to load full table

If you have custom section view you can add a weak reference to it in your view controller and update it whenever you want. Here is my code for reference:

@property (weak, nonatomic) UILabel *tableHeaderLabel;

....

-(UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    UITableViewHeaderFooterView *myHeader = [[UITableViewHeaderFooterView alloc] init];

    UILabel *titleLabel = [[UILabel alloc] init];
    [titleLabel setFrame:CGRectMake(20, 0, 280, 20)];
    [titleLabel setTextAlignment:NSTextAlignmentRight];
    [titleLabel setBackgroundColor:[UIColor clearColor]];
    [titleLabel setFont:[UIFont systemFontOfSize:12]];

    [myHeader addSubview:titleLabel];

    self.tableHeaderLabel = titleLabel; //save reference so we can update the header later

    return myHeader;
}

Then later on you can update your section like this:

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    self.tableHeaderLabel.text = [NSString stringWithFormat:@"Showing row: %ld", indexPath.row];
}
