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 ()

Define a View Controller

Let ONE_VC = Oneviewcontroller (Nibname:nil,bundle:nil);

Creating a navigation controller

Let Nvc=uinavigationcontroller (ROOTVIEWCONTROLLER:ONE_VC);

Setting the root view

self.window!. ROOTVIEWCONTROLLER=NVC;

return True

}

Func applicationwillresignactive (application:uiapplication) {

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

Use the This method to the 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 the This method to release the shared resources, save user data, invalidate timers, and store enough application state info Rmation to the restore your application to the 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's can undo many of the changes made on entering the background.

}

Func applicationdidbecomeactive (application:uiapplication) {

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

}

Func applicationwillterminate (application:uiapplication) {

Called when the application are about to terminate. Save data if appropriate. See also Applicationdidenterbackground:.

}

Set Navigation bar title

Item title//item style//target all//nxet event-triggered method name

Let Nextitem=uibarbuttonitem (title: "Next Page", Style:.) Plain,target:self,action: "Next");

Add to the navigation bar

Item Event

Func Next ()

println ("Click on Next Page");

Define a controller

Let TOW_VC = Towviewcontroller ();

Push into the next view

Self.navigationController.pushViewController (tow_vc,animated:true);

}

Override Func didreceivememorywarning () {

Super.didreceivememorywarning ()

Dispose of any resources the can be recreated.

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

Pass the selected object to the new view controller.
