UITableView titleForHeaderInSection shows all caps

Yes, we had very much a similar problem to this, and my own solution was as follows:

The Apple UITableViewHeaderFooterView documentation (the link to it is irritatingly long but you can find it easily with your favourite search engine) says you can access the textLabel of the header view without having to format your own view via viewForHeaderInSection method.

textLabel A primary text label for the view. (read-only)

@property(nonatomic, readonly, retain) UILabel *textLabel Discussion Accessing the value in this property causes the view to create a default label for displaying a detail text string. If you are managing the content of the view yourself by adding subviews to the contentView property, you should not access this property.

The label is sized to fit the content view area in the best way possible based on the size of the string. Its size is also adjusted depending on whether there is a detail text label present.

With some additional searching the best place to modify the label text was the willDisplayHeaderView method (suggested in How to implement `viewForHeaderInSection` on iOS7 style?).

So, the solution I came up with is pretty simple and just does a transformation of the text label string, after it's actually been set by titleForHeaderInSection:

-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
        //I have a static list of section titles in SECTION_ARRAY for reference.
        //Obviously your own section title code handles things differently to me.
    return [SECTION_ARRAY objectAtIndex:section];
}

and then simply call the willDisplayHeaderView method to modify how it looks:

- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section
{
    if([view isKindOfClass:[UITableViewHeaderFooterView class]]){
        UITableViewHeaderFooterView *tableViewHeaderFooterView = (UITableViewHeaderFooterView *) view;
        tableViewHeaderFooterView.textLabel.text = [tableViewHeaderFooterView.textLabel.text capitalizedString];
    }
}

You can put in your own 'if' or 'switch' clauses in there as the section number is also passed to the method, so hopefully it'll allow you to show your user/client name in capitalised words selectively.

solution which i found is add Title in "titleForHeaderInSection" method

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
   return @"Table Title";
}

and then call the willDisplayHeaderView method to Update :

- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section 
{
    UITableViewHeaderFooterView *header = (UITableViewHeaderFooterView *)view;
    header.textLabel.textColor = [UIColor darkGrayColor];
    header.textLabel.font = [UIFont boldSystemFontOfSize:18];
    CGRect headerFrame = header.frame;
    header.textLabel.frame = headerFrame;
    header.textLabel.text= @"Table Title";
    header.textLabel.textAlignment = NSTextAlignmentLeft;
}

If you want to just keep the string as it is, you could simply do this:

- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section {
    if ([view isKindOfClass:[UITableViewHeaderFooterView class]] && [self respondsToSelector:@selector(tableView:titleForHeaderInSection:)]) {
        UITableViewHeaderFooterView *headerView = (UITableViewHeaderFooterView *)view;
        headerView.textLabel.text = [self tableView:tableView titleForHeaderInSection:section];
    }
}

Swift solution:

func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
    if let headerView = view as? UITableViewHeaderFooterView, self.respondsToSelector(Selector("tableView:titleForHeaderInSection:")) {
        headerView.textLabel?.text = self.tableView(tableView, titleForHeaderInSection: section)
    }
}

In Swift,

override func tableView(tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
    let headerView = view as! UITableViewHeaderFooterView
    headerView.textLabel.text = "My_String"
}
