基于swift的UItableview

import UIKitclass ViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {    var tableview :UITableView!    var cellarray :NSMutableArray!    overridefunc viewDidLoad() {        super.viewDidLoad()        // Do any additional setup after loading the view, typically from a nib.        self.cellarray = ["1","2","3","4","5","6","7","8","9","10"]        tableViewSubView()    }    func tableViewSubView()    {        self.tableview =UITableView(frame: self.view!.frame, style:UITableViewStyle.Plain)        self.tableview?.dataSource =self;        self.tableview!.delegate =self;        self.view!.addSubview(self.tableview!)    }    // 数据源方法,返回多少组    func numberOfSectionsInTableView(tableView:UITableView) -> Int {        return1;    }    // 每组有多少行    func tableView(tableView:UITableView, numberOfRowsInSection section:Int) -> Int {        returnself.cellarray.count;    }    // 每行展示什么内容    func tableView(tableView:UITableView, cellForRowAtIndexPath indexPath:NSIndexPath) -> UITableViewCell {        var cell=tableView.dequeueReusableCellWithIdentifier("reuse")as? UITableViewCell        if (cell==nil){            cell=UITableViewCell(style: .Default, reuseIdentifier:"reuse")        }        //        cell!.textLabel!.text="\(indexPath.row)"        cell?.textLabel?.text = self.cellarray[indexPath.row]as? String        return cell!    }    overridefunc didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.    }}
