Hi All, Apple has introduced new programming language called "Swift" and iOS 8. Hope all of you know about this. I have downloaded XCode 6.0 beta from "developer.apple.com" and started playing with it. I have created a UITableView demo and thought of sharing it with you.
I have created a empty application and created new UIViewController subclass "TableViewController" and corresponding xib file called "TableView".
Added code in AppDelegate.swift to create a new navigation controller with TableViewController as root view controller :
In TableViewController class, I took elements as an optional array and implemented UITableViewDatasource methods :
I have created a empty application and created new UIViewController subclass "TableViewController" and corresponding xib file called "TableView".
Added code in AppDelegate.swift to create a new navigation controller with TableViewController as root view controller :
var tableVC : TableViewController = TableViewController(nibName: "TableView", bundle: NSBundle.mainBundle())
var navVC : UINavigationController = UINavigationController(rootViewController: tableVC)
self.window!.rootViewController = navVC
now, func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool of AppDelegate class will look like below :
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
var tableVC : TableViewController = TableViewController(nibName: "TableView", bundle: NSBundle.mainBundle())
var navVC : UINavigationController = UINavigationController(rootViewController: tableVC)
self.window!.rootViewController = navVC
self.window!.backgroundColor = UIColor.whiteColor()
self.window!.makeKeyAndVisible()
return true
}
import UIKit
class TableViewController: UIViewController, UITableViewDelegate, UITableViewDataSource
{
var elements : Array<AnyObject>?
init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {
super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
}
override func viewDidLoad()
{
super.viewDidLoad()
self.title = "Table View"
elements = ["One","Two","Three","Five","Six","Seven","Eight","Nine","Ten"]
}
func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int
{
return elements!.count;
}
func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!
{
var cell = tableView.dequeueReusableCellWithIdentifier("Cell") as UITableViewCell!
if cell == nil
{
cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")
}
cell.textLabel.text = elements![indexPath.row] as String
return cell
}
}
Here is the output :
Here is the Source Code.
