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

iOS 8 +

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

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:]

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;
}

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];

In iOS 7.0.4 I created a custom header with it's own XIB. Nothing mentioned here before worked. It had to be the subclass of the UITableViewHeaderFooterView to work with the dequeueReusableHeaderFooterViewWithIdentifier: and it seems that class is very stubborn regarding the background color. So finally I added an UIView (you could do it either with code or IB) with name customBackgroudView, and then set it's backgroundColor property. In layoutSubviews: I set that view's frame to bounds. It work with iOS 7 and gives no glitches.

// in MyTableHeaderView.xib drop an UIView at top of the first child of the owner
// first child becomes contentView

// in MyTableHeaderView.h
@property (nonatomic, weak) IBOutlet UIView * customBackgroundView;

// in MyTableHeaderView.m
-(void)layoutSubviews;
{
    [super layoutSubviews];

    self.customBackgroundView.frame = self.bounds;
}
// if you don't have XIB / use IB, put in the initializer:
-(id)initWithReuseIdentifier:(NSString *)reuseIdentifier
{
    ...
    UIView * customBackgroundView = [[UIView alloc] init];
    [self.contentView addSubview:customBackgroundView];
    _customBackgroundView = customBackgroundView;
    ...
}


// in MyTableViewController.m
-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    MyTableHeaderView * header = [self.tableView
                                          dequeueReusableHeaderFooterViewWithIdentifier:@"MyTableHeaderView"];
    header.customBackgroundView.backgroundColor = [UIColor redColor];
    return header;
}
