You could design your own header, like you would design a custom cell in a table view. Or you could just add an image like so:
您可以设计自己的标题，就像在表格视图中设计自定义单元格一样。或者你可以像这样添加一个图像：
func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
var myCustomView: UIImageView
var myImage: UIImage = UIImage(named: "myImageResource")
myCustomView.image = myImage
let header: UITableViewHeaderFooterView = view as UITableViewHeaderFooterView
header.addSubview(myCustomView)
return header
}
Then you can simply add your section title UILabel as another subview.
然后你可以简单地将你的部分标题 UILabel 添加为另一个子视图。

Simply Add the following code in your viewDidLoad()method.
只需在您的viewDidLoad()方法中添加以下代码。
var frame = CGRectMake(0, 0, self.view.frame.size.width, 200)
var headerImageView = UIImageView(frame: frame)
var image: UIImage = UIImage(named: "yourImage")!
headerImageView.image = image
youTableView.tableHeaderView = headerImageView

I use this method below in my proj.
我在下面的项目中使用此方法。
override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
{
let uilbl = UILabel()
//uilbl.numberOfLines = 0
//uilbl.lineBreakMode = NSLineBreakMode.ByWordWrapping
//uilbl.text = "blablabla"
uilbl.sizeToFit()
uilbl.backgroundColor = UIColor(patternImage: UIImage(named: "yr-img-name")!)
return uilbl
}

let image = UIImage(named: "Games.png");
