22. }
23. funcinitView(){

8. importUIKit
9. @UIApplicationMain
10. AppDelegate:UIResponder,UIApplicationDelegate{
12. window:UIWindow?
13. funcapplication(application:UIApplication,didFinishLaunchingWithOptionslaunchOptions:NSDictionary?)->Bool{
14. self.window=UIWindow(frame:UIScreen.mainScreen().bounds)
15. //Overridepointforcustomizationafterapplicationlaunch.
16. varrootView=RootViewController()
17. varnav=UINavigationController(rootViewController:rootView)
18. self.window!.rootViewController=nav;
19. self.window!.backgroundColor=UIColor.whiteColor()
20. self.window!.makeKeyAndVisible()
21. true
22. }
23. funcapplicationWillResignActive(application:UIApplication){
24. //Sentwhentheapplicationisabouttomovefromactivetoinactivestate.Thiscanoccurforcertaintypesoftemporaryinterruptions(suchasanincomingphonecallorSMSmessage)orwhentheuserquitstheapplicationanditbeginsthetransitiontothebackgroundstate.
