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;
}
}

如果有人需要斯威夫特,请保留头衔:
override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let view = UIView(frame: CGRect(x: 0,y: 0,width: self.tableView.frame.width, height: 30))
view.backgroundColor = UIColor.redColor()
let label = UILabel(frame: CGRect(x: 15,y: 5,width: 200,height: 25))
label.text = self.tableView(tableView, titleForHeaderInSection: section)
view.addSubview(label)
return view
}
iOS 8 +
func tableView(tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
tableView.tableHeaderView?.backgroundColor = UIColor.blue()
}
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
-(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 whiteColor]; // substitute your color here
content.backgroundColor = color;
[castView.textLabel setTextColor:[UIColor blackColor]];
}
}
以下解决方案适用于Swift 1.2和iOS 8+
override func tableView(tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
// This changes the header background
view.tintColor = UIColor.blueColor()
// Gets the header view as a UITableViewHeaderFooterView and changes the text colour
var headerView: UITableViewHeaderFooterView = view as! UITableViewHeaderFooterView
headerView.textLabel.textColor = UIColor.redColor()
}
