Introduction to push features: what needs to be done on the app side

Introduction to push Features

The process for implementing the push is as follows:

From the app registration push feature to the APNS server to send push messages to the device, there are five steps.

Once the push registration is complete, the application's own server provides the push as provider.

App-side implementations

In terms of code, push registration, monitoring, and processing are all concentrated in the Appdelegate class:
1. (BOOL) Application: (UIApplication *) application didfinishlaunchingwithoptions: (nsdictionary *) launchOptions
Two main functions are implemented in the method body:
The first is to complete the Push function registration request, that is, when the program starts to eject whether to use the push function;
Second, the implementation of the program start is triggered by the push message window, where the push content can be processed;
1.

-(BOOL) Application: (UIApplication *) application didfinishlaunchingwithoptions: (Nsdictionary *) Launchoptions{self.window=[[[UIWindow alloc] initwithframe:[[uiscreen mainscreen] bounds]] autorelease];//Override point for customization after application launch.Self.viewcontroller =[[[ Viewcontroller alloc] init] Autorelease];self.window.rootviewcontroller=Self.viewcontroller; [Self.window setbackgroundcolor:[uicolor colorwithpatternimage:[uiimage imagenamed:@"Background.png"]]]; [Self.window makekeyandvisible]; [[UIApplication Sharedapplication] registerforremotenotificationtypes: (Uiremotenotificationtypealert| Uiremotenotificationtypebadge |Uiremotenotificationtypesound)];//The procedure is not done by the push service, that is, the user clicks the push notification to complete theif(launchoptions) {nsdictionary* Pushnotificationkey =[Launchoptions Objectforkey:uiapplicationlaunchoptionsremotenotificationkey];if(pushnotificationkey) {Uialertview*alert =[[Uialertview alloc]initwithtitle:@] Push notification "message:@" This is a program launched through a push window where you can process the push content "Delegate: nilcancelbuttontitle:@ "Know" otherbuttontitles:nil, nil]; [Alert show]; [Alert release];}}returnYES;}

2. Receive the only device token returned from the Apple server, which is the basis on which the push server sends the push message, so it needs to be sent back to the push server to save

-(void) Application: (UIApplication *) app Didregisterforremotenotificationswithdevicetoken: (NSData *) Devicetoken {nsstring* token = [NSString stringWithFormat:@ "%@" Generated devtoken:%@ ", token); // send Devicetoken to our push server devicesender* sender = [[[Devicesender Alloc]initwithdelegate:self]autorelease];[ Sender Senddevicetopushserver:token];}

3. Receive the error when registering the push notification function, and do the related processing:

-(void) Application: (UIApplication *) app Didfailtoregisterforremotenotificationswitherror: (Nserror *  error occurred while registering the push feature, error message: \ n%@ ", err);}

4. Received the push message, parsing processing

- (void) Application: (UIApplication *) application didreceiveremotenotification: (Nsdictionary *) Userinfo{nslog (@ "\napnsDidreceiveremotenotification,receive data:\n%@ ", userInfo);//set the tag number on icon to 0,Application.applicationiconbadgenumber =0;if([[UserInfo Objectforkey:@"APS"] objectforkey:@ "alert"]!=NULL) {Uialertview* Alert = [[Uialertview alloc] initwithtitle:@ "* * Push message * *"Message:[[userinfo Objectforkey:@"APS"] objectforkey:@ "alert"]Delegate: selfcancelbuttontitle:@ "Off" otherbuttontitles:@ "Handling push content", Nil];alert.tag=Alert_tag_push; [Alert show];}}

Through the above code, the basic push function development has been completed, need to push the server support, please resolve yourself.
