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
}
希望UITableViewDelegate协议中的这个方法能让你开始:
objective - c:
- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)] autorelease];
if (section == integerRepresentingYourSectionOfInterest)
[headerView setBackgroundColor:[UIColor redColor]];
else
[headerView setBackgroundColor:[UIColor clearColor]];
return headerView;
}
迅速:
func tableView(_ tableView: UITableView!, viewForHeaderInSection section: Int) -> UIView!
{
let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.bounds.size.width, height: 30))
if (section == integerRepresentingYourSectionOfInterest) {
headerView.backgroundColor = UIColor.redColor()
} else {
headerView.backgroundColor = UIColor.clearColor()
}
return headerView
}

let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.bounds.size.width, height: 30))
if (section == integerRepresentingYourSectionOfInterest) {
headerView.backgroundColor = UIColor.red
} else {
headerView.backgroundColor = UIColor.clear
}
return headerView
}
替换[UIColor redColor]与任何你想要的UIColor。您可能还希望调整headerView的尺寸。

要更改UITableView Section的头视图的背景颜色、文本标签颜色和字体,只需覆盖你的表视图的willDisplayHeaderView,如下所示:
override func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
let header = view as! UITableViewHeaderFooterView
header.backgroundView?.backgroundColor = .white
header.textLabel?.textColor = .black
header.textLabel?.font = UIFont(name: "Helvetica-Bold", size: 14)
}
这对我来说非常有效;希望它也能帮助到你!
只需要改变头视图图层的颜色
- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section { UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)] autorelease]; headerView.layer.backgroundColor = [UIColor clearColor].CGColor }
iOS 8 +
func tableView(tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
tableView.tableHeaderView?.backgroundColor = UIColor.blue()
}
