编辑静态tableView单元格部分

Question

I have a static tableView with some custom cells. What I wan't to do is change the section titles programmatically. As far as I know, because the cells are static, I can't use methods like cellForRowAtIndexPath and so on, so my question is, is it possibly to change them like.

self.tableView.section1.text = @"title1"; // something like this?

I've tried to create an IBOutlet of the section but I get the following error:

Unknown type name 'UITableViewSection': did you mean 'UITableViewStyle?'

What I can do is edit the content of the cells, but not the header.

Thanks!

Use viewForHeaderInSection method.

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {


        UILabel *label1 = [[UILabel alloc] init];
        label1.frame = CGRectMake(0, 0, 190, 20);
        label1.textColor = [UIColor blackColor];
        // label1.font = [UIFont fontWithName:@"Helvetica Bold" size:16];
        [label1 setFont:[UIFont fontWithName:@"Arial-BoldMT" size:14]];
        label1.textAlignment = UITextAlignmentCenter;

        label1.text =[NSString stringWithFormat:@"Title %d",section];
// If your title are inside an Array then Use Below Code 

       label1.text =[titleArray objectAtindex:section];

        label1.textColor = [UIColor whiteColor];
        label1.backgroundColor = [UIColor clearColor];




UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 30)];
    [view addSubview:label1];

    view.backgroundColor = [UIColor orangeColor];
         return view;

    }

if You want to use titleForHeaderInSection then use below code.

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section 
{

return [NSString stringWithFormat:@"Title %d",section];
// If your title are inside an Array then Use Below Code 

       return [titleArray objectAtindex:section];
}

You can use the UITableViewDelegate Protocol method tableview:titleForHeaderInSection:

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {

    NSString *sectionTitle = @"";

    switch (section) {

        case 0: sectionTitle = @"Section 1"; break;
        case 1: sectionTitle = @"Section 2"; break;
        case 2: sectionTitle = @"Section 3"; break;

        default:
            break;
    }

    return sectionTitle;
}

Make sure you declare your <UITableViewDelegate > in your .h file:

@interface SettingsViewController : UITableViewController <UITableViewDelegate> {

}

If you need to change the headers when the view is displayed 'live' you can do so like this:

int sectionNumber = 0;
[self.tableView headerViewForSection:sectionNumber].textLabel.text = @"Foo Bar";

But doing so doesn't seem to change the size of the label frame. I just made mine larger in advance. More details here.
