使用UIAppearance,你可以为你的应用程序中的所有头部更改它,如下所示:
UITableViewHeaderFooterView.appearance()。backgroundColor = theme.subViewBackgroundColor

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
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;
}
swift 5 +
在willDisplayHeaderView方法中
func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
//For Header Background Color
view.tintColor = .black
// For Header Text Color
let header = view as! UITableViewHeaderFooterView
header.textLabel?.textColor = .white
}
我希望这对你有所帮助:]
在UITableViewHeaderFooterView上设置背景色已弃用。请使用contentView。写成backgroundColor代替。

我成功地通过添加模糊效果改变了部分背景颜色(这真的很酷)。要轻松更改部分的背景颜色:
首先转到Storyboard并选择表视图 转到属性检查器 列表项 向下滚动到视图 改变“背景”
然后为模糊效果,添加到代码:
override func tableView(tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
// This is the blur effect
let blurEffect = UIBlurEffect(style: .Light)
let blurEffectView = UIVisualEffectView(effect: blurEffect)
// Gets the header view as a UITableViewHeaderFooterView and changes the text colour and adds above blur effect
let headerView: UITableViewHeaderFooterView = view as! UITableViewHeaderFooterView
headerView.textLabel!.textColor = UIColor.darkGrayColor()
headerView.textLabel!.font = UIFont(name: "HelveticaNeue-Light", size: 13)
headerView.tintColor = .groupTableViewBackgroundColor()
headerView.backgroundView = blurEffectView
}
