我认为这段代码还不错。

func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let headerView = tableView.dequeueReusableHeaderFooterViewWithIdentifier(MyHeaderView.reuseIdentifier) as MyHeaderView
    let backgroundView = UIView()
    backgroundView.backgroundColor = UIColor.whiteColor()
    headerView.backgroundView = backgroundView
    headerView.textLabel.text = "hello"
    return headerView
}

如果你不想创建一个自定义视图，你也可以像这样改变颜色(需要iOS 6):

-(void) tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section {
    if ([view isKindOfClass: [UITableViewHeaderFooterView class]]) {
        UITableViewHeaderFooterView* castView = (UITableViewHeaderFooterView*) view;
        UIView* content = castView.contentView;
        UIColor* color = [UIColor colorWithWhite:0.85 alpha:1.]; // substitute your color here
        content.backgroundColor = color;
    }
}

Swift使它变得非常简单。只需将其添加到类中，并根据需要设置颜色。

override func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
        view.backgroundColor = UIColor(red: 0.094, green: 0.239, blue: 0.424, alpha: 1.0)
    }

或者是简单的颜色

override func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
        view.backgroundColor = UIColor.white
    }

Swift 5更新

override func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
        view.tintColor = UIColor(red: 0.094, green: 0.239, blue: 0.424, alpha: 1.0)
    }

或者是简单的颜色

override func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
        view.tintColor = UIColor.white
    }

Although func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) will work as well, you can acheive this without implementing another delegate method. in you func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? method, you can use view.contentView.backgroundColor = UIColor.white instead of view.backgroundView?.backgroundColor = UIColor.white which is not working. (I know that backgroundView is optional, but even when it is there, this is not woking without implementing willDisplayHeaderView

 -(void) tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view
  forSection:(NSInteger)section
  {
        if ([view isKindOfClass: [UITableViewHeaderFooterView class]])
        {
             UITableViewHeaderFooterView *castView = (UITableViewHeaderFooterView *) view;
             UIView *content = castView.contentView;
             UIColor *color = [UIColor whiteColor]; // substitute your color here
             content.backgroundColor = color;
             [castView.textLabel setTextColor:[UIColor blackColor]];
        }
 }

使用RubyMotion / RedPotion，将其粘贴到你的桌面屏幕:

  def tableView(_, willDisplayHeaderView: view, forSection: section)
    view.textLabel.textColor = rmq.color.your_text_color
    view.contentView.backgroundColor = rmq.color.your_background_color
  end

效果好极了!
