本文介绍了一个使用 Swift 实现 UITableView 的示例应用。该应用通过创建 AppDelegate 和 RootViewController 类来展示如何初始化并配置 UITableView，包括设置数据源、代理方法以及单元格的加载与显示。

swift UITableView 表视图

// AppDelegate.swift

// swiftTableView

// Created by baojia on 14-6-30.

import UIKit

@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {

self.window = UIWindow(frame: UIScreen.mainScreen().bounds)

// Override point for customization after application launch.

self.window!.backgroundColor = UIColor.whiteColor()

self.window!.makeKeyAndVisible()

self.window!.rootViewController=RootViewController();

return true

}

func applicationWillResignActive(application: UIApplication) {

// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.

// Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.

}

func applicationDidEnterBackground(application: UIApplication) {

// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.

// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.

}

func applicationWillEnterForeground(application: UIApplication) {

// Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.

}

func applicationDidBecomeActive(application: UIApplication) {

// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.

}

func applicationWillTerminate(application: UIApplication) {

// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.

}

// RootViewController.swift

// swiftTableView

// Created by baojia on 14-6-30.

import UIKit

class RootViewController:UIViewController,UITableViewDataSource,UITableViewDelegate

{

// init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {

// super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)

// // Custom initialization

// }

// 生命全局变量

//数据源

var dataArr = NSMutableArray();

//声明tableView

var tableView :UITableView?;

override func viewDidLoad()

{

super.viewDidLoad()

// 初始化数据

setData();

//设置布局

setLayout();

// Do any additional setup after loading the view.

}

func setData()

{

for(var i=0 ;i<20 ;i++)

{

dataArr.addObject("\(i)");

}

println("初始数据完毕，如下:\(dataArr)");

}

//布局方法

func setLayout()

{

var rect=self.view.bounds;

// 创建TableView

tableView = UITableView(frame:rect,style:.Plain);

// 设置代理

tableView!.delegate=self;

tableView!.dataSource=self;

//添加视图

self.view.addSubview(tableView);

}

//UITableViewDataSource 代理办法

func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int

{

return dataArr.count;

}

func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!

{

let CellId="my cell";

var cell = tableView.dequeueReusableCellWithIdentifier(CellId) as? UITableViewCell;

if(cell==nil)

{

cell=UITableViewCell(style:.Default,reuseIdentifier:CellId);

}

var s = dataArr.objectAtIndex(indexPath.row) as? String;

cell!.textLabel.text = s;

return cell;

}

override func didReceiveMemoryWarning() {

super.didReceiveMemoryWarning()

// Dispose of any resources that can be recreated.

}

// #pragma mark - Navigation

// In a storyboard-based application, you will often want to do a little preparation before navigation

override func prepareForSegue(segue: UIStoryboardSegue?, sender: AnyObject?) {

// Get the new view controller using [segue destinationViewController].

// Pass the selected object to the new view controller.

}
