下面是如何在头视图中添加图像:

- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section 
{
    UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)] autorelease];
    UIImageView *headerImage = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"top-gery-bar.png"]] autorelease];

    headerImage.frame = CGRectMake(0, 0, tableView.bounds.size.width, 30);

    [headerView addSubview:headerImage];

    return headerView;
}

iOS 13> swift 5

func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int){视图。tintColor = UIColor。红}

 -(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]];
        }
 }

我成功地通过添加模糊效果改变了部分背景颜色(这真的很酷)。要轻松更改部分的背景颜色:

首先转到Storyboard并选择表视图 转到属性检查器 列表项 向下滚动到视图 改变“背景”

然后为模糊效果，添加到代码:

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

    // This is the blur effect

    let blurEffect = UIBlurEffect(style: .Light)
    let blurEffectView = UIVisualEffectView(effect: blurEffect)

    // Gets the header view as a UITableViewHeaderFooterView and changes the text colour and adds above blur effect
    let headerView: UITableViewHeaderFooterView = view as! UITableViewHeaderFooterView
    headerView.textLabel!.textColor = UIColor.darkGrayColor()
    headerView.textLabel!.font = UIFont(name: "HelveticaNeue-Light", size: 13)
    headerView.tintColor = .groupTableViewBackgroundColor()
    headerView.backgroundView = blurEffectView

}

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

以下解决方案适用于Swift 1.2和iOS 8+

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

    // This changes the header background
    view.tintColor = UIColor.blueColor()

    // Gets the header view as a UITableViewHeaderFooterView and changes the text colour
    var headerView: UITableViewHeaderFooterView = view as! UITableViewHeaderFooterView
    headerView.textLabel.textColor = UIColor.redColor()

}
