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

}

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
    }

希望UITableViewDelegate协议中的这个方法能让你开始:

objective - c:

- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section 
{
  UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)] autorelease];
  if (section == integerRepresentingYourSectionOfInterest)
     [headerView setBackgroundColor:[UIColor redColor]];
  else 
     [headerView setBackgroundColor:[UIColor clearColor]];
  return headerView;
}

迅速:

func tableView(_ tableView: UITableView!, viewForHeaderInSection section: Int) -> UIView!
{
  let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.bounds.size.width, height: 30))
  if (section == integerRepresentingYourSectionOfInterest) {
    headerView.backgroundColor = UIColor.redColor()
  } else {
    headerView.backgroundColor = UIColor.clearColor()
  }
  return headerView
}

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
    {
        let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.bounds.size.width, height: 30))
        if (section == integerRepresentingYourSectionOfInterest) {
            headerView.backgroundColor = UIColor.red
        } else {
            headerView.backgroundColor = UIColor.clear
        }
        return headerView
    }

替换[UIColor redColor]与任何你想要的UIColor。您可能还希望调整headerView的尺寸。

iOS 8 +

func tableView(tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
        tableView.tableHeaderView?.backgroundColor = UIColor.blue()
}

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

要更改UITableView Section的头视图的背景颜色、文本标签颜色和字体,只需覆盖你的表视图的willDisplayHeaderView,如下所示:

override func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
        let header = view as! UITableViewHeaderFooterView
        header.backgroundView?.backgroundColor = .white
        header.textLabel?.textColor = .black
        header.textLabel?.font = UIFont(name: "Helvetica-Bold", size: 14)
} 

这对我来说非常有效;希望它也能帮助到你!
