Swift Local notification, remote notification

Both remote push and local push require a registration notification code

IOS 8 divides the registration of the original one step remotenotification into two parts, one for registering the newly introduced "uiusernotificationsettings", and the other for remotenotifications.

In fact, Apple has unified remotenotification and localnotification in IOS 8. The two notifications will be unified by Uiusernotificationsettings to manage the user interface related things: tags, sounds, and reminders.  In addition to the unified user interface notification, Uiusernotificationsettings also introduces Uiusernotificationcategory, which allows users to easily perform some quick actions directly on Notification (action ）。

if (uiapplication instancesrespondtoselector ("Selector (" Registerusernotificationsettings: "))) {

Application. Registerusernotificationsettings (Uiusernotificationsettings (Fortypes:uiusernotificationtype.  Sound | Uiusernotificationtype.  Alert | Uiusernotificationtype. Badge, Categories:nil))

} else {

Application. Registerforremotenotificationtypes (. Alert |. Sound |. Badge)

}

Then, write related code such as remote push, local notification, etc. in Appdelegate.swift

Receive local notifications

Func application (application:uiapplication, didreceivelocalnotification notification:uilocalnotification) {

var Alertview = Uialertview (title: "System Local Notification", Message:notification. Alertbody, Delegate:nil, Cancelbuttontitle: "Back")

Alertview. Show ()

}

//Remote push notification registration successful

Func application (application:uiapplication, Didregisterforremotenotificationswithdevicetoken devicetoken:nsdata) {

println (devicetoken. Description)

}

Remote Push notification registration failed

Func application (application:uiapplication, Didfailtoregisterforremotenotificationswitherror error:nserror) {

If error. Code = = 3010 {

println ("Push Notifications is not supported in the IOS Simulator.")

} else {

println ("Application:didfailtoregisterforremotenotificationswitherror:/(Error)")

}

}

Remote push notification received before 8.0

Func application (application:uiapplication, didreceiveremotenotification userInfo: [Nsobject:anyobject]) {

Let Notif = UserInfo as Nsdictionary

Let Apsdic = Notif. Objectforkey ("APS") as Nsdictionary

Let Alertdic = Apsdic. Objectforkey ("alert") as String

var Alertview = Uialertview (title: "System Local Notification", Message:alertdic, Delegate:nil, Cancelbuttontitle: "Back")

Alertview. Show ()

}

Receive remote push notifications after 8.0

Func application (application:uiapplication, didreceiveremotenotification userInfo: [Nsobject:anyobject], FetchCompl Etionhandler Completionhandler: (Uibackgroundfetchresult), Void) {

Let Notif = UserInfo as Nsdictionary

Let Apsdic = Notif. Objectforkey ("APS") as Nsdictionary

Let Alertdic = Apsdic. Objectforkey ("alert") as String

var Alertview = Uialertview (title: "Remote Push Notification", Message:alertdic, Delegate:nil, Cancelbuttontitle: "Back")

Alertview. Show ()

}

Registration Notice alert, sound, badge (after 8.0, you must add the following code, or registration fails)

Func application (application:uiapplication, didregisterusernotificationsettings notificationsettings: Uiusernotificationsettings) {

Application. Registerforremotenotifications ()

}
