1.自定义cell

//// FirstSwiftCell.swift// SwiftDeKeYiCai////import UIKitclass FirstSwiftCell: UITableViewCell { var titleLabel:UILabel? var picImageVIew:UIImageView? override init(style: UITableViewCellStyle, reuseIdentifier: String?) { super.init(style: style, reuseIdentifier: reuseIdentifier) self.setUpUI() } required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) } func setUpUI() { self.titleLabel = UILabel.init() self.titleLabel?.backgroundColor = UIColor.clear; self.titleLabel?.frame = CGRect(x:65, y:0, width:100, height:50) self.titleLabel?.textColor = UIColor.magenta self.titleLabel?.text = "第一条显示的数据" self.titleLabel?.font = UIFont.systemFont(ofSize: 15) self.titleLabel?.textAlignment = NSTextAlignment.left; self.contentView.addSubview(self.titleLabel!) self.picImageVIew = UIImageView() self.picImageVIew?.frame = CGRect(x:15, y:5, width:40, height:40) self.picImageVIew?.image = UIImage.init(named: "1.png") self.contentView.addSubview(self.picImageVIew!) } }

2.cell添加tableview --创建tableVIew。viewController 代码

//// ViewController.swift// SwiftDeKeYiCai////import Foundationimport UIKitclass ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate { var tableView:UITableView! var array = ["111", "222", "333", "444"] override func viewDidLoad() { super.viewDidLoad() let rect = self.view.frame tableView = UITableView(frame:rect) tableView.delegate = self tableView.dataSource = self let view = UIView() tableView.tableFooterView = view self.view.addSubview(tableView) tableView.register(FirstSwiftCell.self, forCellReuseIdentifier: "cellid") } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } func numberOfSections(in tableView: UITableView) -> Int { return 1; } func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return array.count; } func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat { return 50; } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cellid="cellid" var cell:FirstSwiftCell = tableView.dequeueReusableCell(withIdentifier: cellid) as! FirstSwiftCell if cell.isEqual(nil) { cell=FirstSwiftCell(style: UITableViewCellStyle.default, reuseIdentifier: cellid) } cell.selectionStyle = UITableViewCellSelectionStyle.none cell.titleLabel?.text = array[indexPath.row] return cell } func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { }}
