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

你可以在main上做。故事板大约2秒。

选择表视图 转到属性检查器 列表项 向下滚动到查看子标题 改变“背景”

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 5 +

在willDisplayHeaderView方法中

func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {

     //For Header Background Color
     view.tintColor = .black

    // For Header Text Color
    let header = view as! UITableViewHeaderFooterView
    header.textLabel?.textColor = .white
}

我希望这对你有所帮助:]

 -(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UIAppearance，你可以为你的应用程序中的所有头部更改它，如下所示:

UITableViewHeaderFooterView.appearance()。backgroundColor = theme.subViewBackgroundColor
