- (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]];
    }
}

对我来说，在浪费了2个小时后，以上这些都不起作用，这就是解决方案。在我的情况下，它是自定义视图，但我不能改变它从storyboard和视图的awakeFromNib出于某种原因。

override func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
        let header = view as! UITableViewHeaderFooterView
        header.contentView.backgroundColor = .white
    }

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;
}

我认为这段代码还不错。

func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let headerView = tableView.dequeueReusableHeaderFooterViewWithIdentifier(MyHeaderView.reuseIdentifier) as MyHeaderView
    let backgroundView = UIView()
    backgroundView.backgroundColor = UIColor.whiteColor()
    headerView.backgroundView = backgroundView
    headerView.textLabel.text = "hello"
    return headerView
}

不要忘记从委托中添加这段代码，否则您的视图将被切断或在某些情况下出现在表后面，相对于您的视图/标签的高度。

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    return 30;
}

如果你正在使用自定义头视图:

class YourCustomHeaderFooterView: UITableViewHeaderFooterView { 

override func awakeFromNib() {
    super.awakeFromNib()
    self.contentView.backgroundColor = .white //Or any color you want
}

}
