Swift push local push (uilocalnotification)

Local push notifications are implemented by instantiating Uilocalnotification. To implement localization push can add code implementation in Appdelegate.swift, this case is a message to the user when the app enters the background.

1. First add code within the Didfinishlaunchingwithoptions method, IOS8 push the message first to obtain the consent of the user, the initial installation of the app will prompt the user whether to allow the program to push messages, this method is the first time the app is run, is executed once, The method is not executed each time it is activated from the background.

Func application (application:uiapplication, didfinishlaunchingwithoptions launchoptions: [Nsobject:anyobject]?)- > Bool {        if (Uidevice.currentdevice () systemversion as NSString). Floatvalue >= 8 {            // Apservice.registerforremotenotificationtypes (                //uiusernotificationtype.badge.rawvalue |                UIUserNotificationType.Sound.rawValue |                UIUserNotificationType.Alert.rawValue,                //categories:nil)                        Application.registerusernotificationsettings (Uiusernotificationsettings (fortypes:                Uiusernotificationtype.badge |                Uiusernotificationtype.sound |                Uiusernotificationtype.alert, Categories:nil)                }                apservice.setupwithoption (launchoptions)        return True    }

2. There are several ways to say it,

1.func applicationwillresignactive (application:uiapplication) {} This event will be triggered when the app will enter the background, lock screen, and call in

2.func Applicationdidenterbackground (application:uiapplication) {} Triggers this event when the app enters the background

3.func Applicationwillenterforeground (application:uiapplication) {} Triggers this event when the app is coming back to the foreground from the background

4.func applicationdidbecomeactive (application:uiapplication) {} Triggers this event when the app becomes active

5.func applicationwillterminate (application:uiapplication) {} This method is triggered when the app exits, and is typically used to save certain data

At this point, write the following code within the Applicationdidenterbackground method:

Func Applicationdidenterbackground (application:uiapplication) {//Use the method to release shared resources, SA  ve user data, invalidate timers, and store enough application state information to restore your application        State-in-case it is terminated later. If your application supports background execution, this method is called instead of Applicationwillterminate:when the        User quits.        Uiapplication.sharedapplication (). Cancelalllocalnotifications () var notification = Uilocalnotification () Notification.firedate = NSDate (). Datebyaddingtimeinterval (1)//setting TimeZone as Localtimezone Noti        Fication.timezone = Nstimezone.localtimezone () Notification.repeatinterval = Nscalendarunit.calendarunitday         Notification.alerttitle = "This is a local notification" notification.alertbody = "Hey,it's great to see you Again" Notification.alertaction = "OK" Notification.soundname = UilocalnoTificationdefaultsoundname//setting app ' s icon badge notification.applicationiconbadgenumber = 1 var userinfo:[nsobject:anyobject] = [Nsobject:anyobject] () userinfo["Klocalnotificationid"] = "LocalNotifi Cationid "userinfo[" key "] =" Attention please "notification.userinfo = UserInfo//uiapplicati On.sharedapplication (). schedulelocalnotification (Notification)//uiapplication.sharedapplication (). Presentlocalnotificationnow (notification) Application.presentlocalnotificationnow (notification)}

When you press the home key to switch the app to the background there will be a push message, and the app's corner mark becomes "1"

3. When the user clicks on the message, it triggers the Didreceivelocalnotification event and writes some code in the event:

Func application (application:uiapplication, Didreceivelocalnotification notification:uilocalnotification) {        Uiapplication.sharedapplication (). Cancelalllocalnotifications () let        userInfo = notification.userinfo!        Let title = userinfo["Key"] as! String                var alert = Uialertview ()        alert.title = title        alert.message = Notification.alertbody        Alert.addbuttonwithtitle (notification.alertaction!)        Alert.cancelbuttonindex = 0        alert.show ()                    //apservice.showlocalnotificationatfront (notification, Identifierkey:nil)    }

4. Remove the icon's corner mark when the program is active

Func applicationdidbecomeactive (application:uiapplication) {        //Restart Any tasks this were paused (or not yet Starte D) While the application is inactive. If the application is previously in the background, optionally refresh the user interface.        Setting the desk top application icon ' s badge as zero        //application.applicationiconbadgenumber = 0        Application . Cancelalllocalnotifications ()        application.applicationiconbadgenumber = 0            }
