在我的例子中，它是这样工作的:

let headerIdentifier = "HeaderIdentifier"
let header = self.tableView.dequeueReusableHeaderFooterView(withIdentifier: headerIdentifier)
header.contentView.backgroundColor = UIColor.white

下面是如何更改文本颜色。

UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake(10, 3, tableView.bounds.size.width - 10, 18)] autorelease];
label.text = @"Section Header Text Here";
label.textColor = [UIColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:0.75];
label.backgroundColor = [UIColor clearColor];
[headerView addSubview:label];

我知道它的答案，以防万一，在Swift使用以下

    override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        let tableViewWidth = self.tableView.bounds

        let headerView = UIView(frame: CGRectMake(0, 0, tableViewWidth.size.width, self.tableView.sectionHeaderHeight))
        headerView.backgroundColor = UIColor.greenColor()

        return headerView
    }

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

你可以这样做，如果你想头部自定义颜色。自iOS 6.0以来，这个解决方案工作得很好。

Objective - C:

[[UITableViewHeaderFooterView appearance] setTintColor:[UIColor redColor]];

迅速:

UITableViewHeaderFooterView.appearance().tintColor = .white

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;
    }
}
