如何在viewForHeaderInSection的tableview中動態更改標題標題？

Question

我需要在tableview標題中設置標題名稱。 IM在

- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section function 
{ 
    IView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)]; 
    UILabel *lbl_header = [[UILabel alloc]initWithFrame:CGRectMake(12, 0, tableView.bounds.size.width, 30)]; 
    lbl_header.tag=1000001; 
    lbl_header.backgroundColor = [UIColor clearColor]; 
    lbl_header.textColor = [UIColor colorWithRed:204.0/255 green:204.0/255 blue:204.0/255 alpha:1.0]; 
    lbl_header.font = [UIFont fontWithName:@"Helvetica-Regular" size:20]; 

    //// get the title name from subclass view controller 

    HOAViewController *obj_hoaview_controll = [[HOAViewController alloc]init]; 
    [obj_hoaview_controll fun_get_login_email_id]; 


    lbl_header.text = str_email_id1;//[udf_value objectForKey:@"StrEmailGet"]; 


    if (section == 0) 
    { 
     [headerView setBackgroundColor:[UIColor colorWithRed:102.0/255 green:102.0/255 blue:102.0/255 alpha:1.0]]; 
     //lbl_header.text = [udf_value objectForKey:@"StrEmailGet"]; 
    } 
    else 
    { 
     [headerView setBackgroundColor:[UIColor clearColor]]; 
    } 
    [headerView addSubview:lbl_header]; 
    return headerView; 
} 

由於使用此代碼的答覆....

使用titleForHeaderInSection，從UITableViewDataSource協議。確保numberOfSectionsInTableView也得到很好的實施。

樣品：

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section 
{ 
    if (section == 0) 
    return @"Title1"; 
    else if (section == 1) 
    return @"Title2"; 
}
