SWIFTUITableView的基本用法

import UIKit

@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate { var window: UIWindow?

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { self.window = UIWindow(frame: UIScreen.mainScreen().bounds) // Override point for customization after application launch. self.window!.backgroundColor = UIColor.whiteColor()

let navigation = UINavigationController(rootViewController: RootViewController()) self.window?.rootViewController = navigation

self.window!.makeKeyAndVisible() return true }}

import UIKit

class RootViewController: UIViewController {

override func loadView() { super.loadView() //初始化UITableView

let tableView = UITableView()

tableView.frame = UIScreen.mainScreen().bounds tableView.dataSource = self tableView.delegate = self

self.view.addSubview(tableView) }

//懒加载数据

lazy var datas:[String] = {

return [\"是⾬是泪\",\"分分钟需要你\",\"伤⼼太平洋\",\"曾经最痛\",\"飘雪\"] }()

override func viewDidLoad() { super.viewDidLoad()

self.title = \"UITableView的基本⽤法\" }}

extension RootViewController:UITableViewDelegate,UITableViewDataSource{

//区的个数

func numberOfSectionsInTableView(tableView: UITableView) -> Int { return 1 }

//在相应区中cell的个数

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return datas.count }

// cell的⾼度

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat { return 60 }

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { //在重⽤机制⾥取出cell

var cell = tableView.dequeueReusableCellWithIdentifier(\"cell\") //如果cell为空则创建 if cell == nil {

cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: \"cell\") }

//设置数据

cell?.textLabel?.text = datas[indexPath.row] return cell! } }
