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;
    }
}

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
    }

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
    }

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;
}

iOS 8 +

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

iOS 13> swift 5

func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int){视图。tintColor = UIColor。红}
