Local push for iOS development

Web push may be the most important, but local push can sometimes be used in projects;

The code below is a little gossip:

1. Add Root View

Self.window.rootViewController = [[Uinavigationcontroller Alloc]initwithrootviewcontroller:[[viewcontroller Alloc]init]];         = [Uicolor whitecolor];    [Self.window makekeyandvisible];

2. Create a button locally to trigger

button = [UIButton buttonwithtype:uibuttontypecustom];     = CGRectMake (+ +);     = [Uicolor bluecolor];    [Button Settitle: @" Here we go. " Forstate:uicontrolstatenormal];    [Button Settitlecolor:[uicolor Whitecolor] forstate:uicontrolstatenormal];     // Binding Method     [button addtarget:self action: @selector (Noticclick:) forcontrolevents:uicontroleventtouchupinside];    [Self.view Addsubview:button];

3, register a notice

//set local notifications pass a time in+ (void) Registerlocalnotification: (nsinteger) alerttime{uilocalnotification*notification =[[Uilocalnotification alloc]init]; //set the time to trigger notificationsNSDate *firedate =[NSDate Datewithtimeintervalsincenow:alerttime]; NSLog (@"firedate=%@", firedate); Notification.firedate=firedate; //Time ZoneNotification.timezone =[Nstimezone Defaulttimezone]; //set the recurrence intervalNotification.repeatinterval =Kcfcalendarunitsecond; //Notification ContentNotification.alertbody =@"It's time to get up ..."; Notification.applicationiconbadgenumber=1; //sounds that are played when notifications are triggeredNotification.soundname =Uilocalnotificationdefaultsoundname; //Notification ParametersNsdictionary *userdict = [Nsdictionary dictionarywithobject:@"Got up and started learning about iOS developed"Forkey:@"Key"]; Notification.userinfo=userdict; //after iOS8, you need to add this registration to be authorized    if([[UIApplication sharedapplication] Respondstoselector: @selector (registerusernotificationsettings:)]) {UIUser NotificationType type= Uiusernotificationtypealert | Uiusernotificationtypebadge |Uiusernotificationtypesound; Uiusernotificationsettings*settings =[Uiusernotificationsettings Settingsfortypes:type        Categories:nil];        [[UIApplication sharedapplication] registerusernotificationsettings:settings]; //the unit that notifies the repeating prompt, which can be day, week, monthNotification.repeatinterval =Nscalendarunitday; } Else {        //the unit that notifies the repeating prompt, which can be day, week, monthNotification.repeatinterval =Nsdaycalendarunit; }    //Perform notification registration[[UIApplication sharedapplication]schedulelocalnotification:notification]; }

4. Call this method

-(void) Noticclick: (ID) sender{    // Call notification    [Viewcontroller Registerlocalnotification:4]; // 4 seconds later }

5, the method of cancellation notice

//cancel a local push notification+(void) Cancellocalnotificationwithkey: (NSString *) key{//get all local notification arraysNsarray *localnotifications =[UIApplication sharedapplication].scheduledlocalnotifications;  for(Uilocalnotification *notificationinchlocalnotifications) {Nsdictionary*userinfo =Notification.userinfo; if(userInfo) {//get notification parameters based on the key specified when setting the notification parametersNSString *info =Userinfo[key]; //If you find a notification that you want to cancel, cancel            if(Info! =Nil)                {[[UIApplication sharedapplication]cancellocalnotification:notification];  Break; }                    }    }}

6. Call this method

//Local notification callback function that is called when the application is in the foreground-(void) Application: (UIApplication *) application didreceivelocalnotification: (nonnull uilocalnotification *) notification{NSLog (@"notif:%@", notification); //It's really a place to deal with interactions.//get the data with the notificationNSString *notmes = [Notification.userinfo objectforkey:@"Key"]; Uialertview*alertview = [[Uialertview alloc]initwithtitle:@"Local notification (front desk)"Message:notmesDelegate: Nil Cancelbuttontitle:@"OK"Otherbuttontitles:nil];        [Alertview show]; //update the number of corner labels displayedNsinteger badge =[UIApplication Sharedapplication].applicationiconbadgenumber; Badge--; Badge= Badge >=0? Badge:0; [UIApplication Sharedapplication].applicationiconbadgenumber=badge; //You can cancel the push when you don't want to push it again.[Viewcontroller Cancellocalnotificationwithkey:@"Key"];}
