设置区域的背景和文本颜色:(感谢William Jockusch和Dj S)

- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section
{
    if ([view isKindOfClass: [UITableViewHeaderFooterView class]]) {
        UITableViewHeaderFooterView* castView = (UITableViewHeaderFooterView*) view;
        castView.contentView.backgroundColor = [UIColor grayColor];
        [castView.textLabel setTextColor:[UIColor grayColor]];
    }
}

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;
}

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

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
    }

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;
}
