I am creating a local notification for a specified date as follows
UILocalNotification *localNotify = [[UILocalNotification alloc]init];
[localNotify setFireDate:notificationDate];
[localNotify setTimeZone:[NSTimeZone localTimeZone]];
[localNotify setAlertBody:#"Daily Items Reminder"];
//[localNotify setAlertLaunchImage:#"blank_Btn"];
[localNotify setAlertAction:#"View"];
[localNotify setSoundName:UILocalNotificationDefaultSoundName];
[localNotify setApplicationIconBadgeNumber:1];
[localNotify setRepeatInterval:NSDayCalendarUnit];
NSDictionary *userDict = [NSDictionary dictionaryWithObject:#"dict"
forKey:#"key"];
localNotify.userInfo = userDict;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotify];
[localNotify release];
In my ApplicationDidFinishLaunching i create an object for UILocalNotification as follows
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent];
UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (notification)
{
NSInteger badgeNumber = notification.applicationIconBadgeNumber;
if (badgeNumber < 0)
{
notification.applicationIconBadgeNumber = 0;
}
else
{
notification.applicationIconBadgeNumber = badgeNumber - 1;
}
[self showAlertMessage:#"didFinishLaunchingWithOptions" withButtons:eOk forDelegate:self];
// open screen
}
}
After clicking on View Button when Local Notification appears the application starts, now launchOption should return the localnotification object thru the key but the it always returns nil as the alertview is not getting called??.. what am i possibly doing wrong??

In my app i am getting data using some network connection
i want to show that data in notification bar (status bar) in iPhone
so how to add data that i can see in status bar of iPhone when i drag it down
i search many tutorials but i did not find any good one please help me
Please tell me some ideas that i can manage my data in notification or any good tutorial
Please suggest any good tutorial so i can manage my dynamic data in notification bar
Thanks
After getting data:
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
localNotif.fireDate = date; // date after 10 sec from now
localNotif.timeZone = [NSTimeZone defaultTimeZone];
// Notification details
localNotif.alertBody = text; // text of you that you have fetched
// Set the action button
localNotif.alertAction = #"View";
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.applicationIconBadgeNumber = 1;
// Specify custom data for the notification
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:#"someValue" forKey:#"someKey"];
localNotif.userInfo = infoDict;
// Schedule the notification
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
To handle onclick of Noification:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
// Add the view controller's view to the window and display.
[window addSubview:viewController.view];
[window makeKeyAndVisible];
application.applicationIconBadgeNumber = 0;
// Handle launching from a notification
UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (localNotif) {
NSLog(#"Recieved Notification %#",localNotif);
}
return YES;
}
- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif {
// Handle the notificaton when the app is running
NSLog(#"Recieved Notification %#",notif);
}
i think, uilocalnotificatios are deprecated. now you can use, UNUserNotificationCenter. we can add image to it as well as shown below:
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
UNAuthorizationOptions options = UNAuthorizationOptionAlert + UNAuthorizationOptionSound;
[center requestAuthorizationWithOptions:options
completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (!granted) {
//NSLog(#"Something went wrong");
}
}];
int dayCounter =5;
int minute = 48;
{
NSDateComponents *components = [[NSDateComponents alloc] init];
components.weekday = dayCounter;
dayCounter++;
components.hour = 12;
components.minute = minute;
UNCalendarNotificationTrigger *trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:components repeats:YES];
UNMutableNotificationContent *objNotificationContent = [[UNMutableNotificationContent alloc] init];
objNotificationContent.title = [NSString localizedUserNotificationStringForKey:#"Notification!" arguments:nil];
objNotificationContent.body = [NSString localizedUserNotificationStringForKey:#"We made a surprise Edit for You" arguments:nil];
objNotificationContent.sound = [UNNotificationSound defaultSound];
objNotificationContent.badge = #([[UIApplication sharedApplication] applicationIconBadgeNumber] + 1);
UNNotificationAttachment *attachment = nil;
NSURL* outputURL = [[NSURL alloc] initFileURLWithPath:filePath];
NSError *attachmentError = nil;
attachment = [UNNotificationAttachment attachmentWithIdentifier:#"image"
URL: outputURL
options:nil
error:&attachmentError];
if (attachmentError) {
return;
}
objNotificationContent.attachments=#[attachment];
NSString *identifier = #"UYLLocalNotification";
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:identifier
content:objNotificationContent trigger: trigger];
[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
if (error != nil) {
NSLog(#"Something went wrong: %#",error);
}
else
{
}
}];
I need background process (for to call a webservice) to call didReceiveLocalNotification:(UILocalNotification *)notification once app launch state, How to do that, please help me.
Thanks in Advance
I tried this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
}
- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif
{
if (app.applicationState == UIApplicationStateInactive )
{
NSLog(#"app not running");
}
else if(app.applicationState == UIApplicationStateActive )
{
NSLog(#"app running");
}
}
This is how I create a local notification which is scheduled at 17:00 on the day this code runs. Once it fires, the method -(void)application:didReceiveLocalNotification: will be called.
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
[calendar setTimeZone:[NSTimeZone localTimeZone]];
NSDateComponents *dateComponents = [calendar components:NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit fromDate:[NSDate date]];
[dateComponents setHour:17];
[dateComponents setMinute:00];
[dateComponents setSecond:00];
NSDate *notificationDate = [calendar dateFromComponents:dateComponents];
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
localNotif.fireDate = notificationDate;
localNotif.timeZone = [NSTimeZone defaultTimeZone];
localNotif.alertBody = #"blah blah blah";
localNotif.alertAction = #"Ok";
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.applicationIconBadgeNumber = 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
Notification is recieved in 2 cases
In application:didFinishLaunchingWithOptions: method, if the app is
neither running nor in the background.
In application:didReceiveLocalNotification: method if the app is
either running or in background. Its almost useless to show the
alert when the app is already running. So you have to show the alert
only when the app was in background at the time the notification
fired. To know if the app is resuming from background use the
applicationWillEnterForeground: method.
l
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (localNotif) {
// Show Alert Here
}
}
Issue is, i put a date picker programmatically. In date picker i just used to display time from 1mins to 23 hours. User is supposed to set the time in the picker, and set up the notification.
Now,i get notification in background but only one time.I have to repeat time until timer will not stop.
I found too many links and source but not able to solve this issue
My Code:
In Appdelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
application.applicationIconBadgeNumber = 0;
//------ Handle launching from a notification-------
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
self.localNotification =[launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (self.localNotification)
{
application.applicationIconBadgeNumber = self.localNotification.applicationIconBadgeNumber-1;
NSLog(#"badge number: %d", application.applicationIconBadgeNumber);
[self playSoundWithNotification:self.localNotification];
}

{
[[UIApplication sharedApplication]cancelAllLocalNotifications];

I am new in iPhone application development. I am doing alarm application. In this application I am using local notification. I am calling notification method in done button action. Now I clicked done button means notification fired correctly. Then again clicked mean also fired, again and again press means working wrongly, but I am used notification fire date time same time. In this time completed means again user click done button means again triggered notification.
I want to fire that particular time. Can you please help me.
Here I am using this source code.
-(IBAction)doneButton
{
[self scheduledNotification];
}
-(void)scheduledNotification

Resource *resourceLoader = [[Resource alloc] init];
NSDictionary *prefDic = [resourceLoader getPlistDataAsDictionary:#"preference"];

Class cls = NSClassFromString(#"UILocalNotification");
if (cls != nil)

hi i not understand what your question but here i post my one example code for LocalNotification just compare it or use this example....
here when user click done button then call "btnGo_Clicked" method
-(IBAction)btnGo_Clicked:(id)sender{
NSLog(#"\n ----------->>Go Clicked");
Class cls = NSClassFromString(#"UILocalNotification");
if (cls != nil) {
NSString *kRemindMeNotificationDataKey = #"kRemindMeNotificationDataKey";
NSDateComponents *dc = [[NSCalendar currentCalendar] components:NSDayCalendarUnit|NSMonthCalendarUnit|NSYearCalendarUnit|NSHourCalendarUnit|NSMinuteCalendarUnit|NSSecondCalendarUnit|NSQuarterCalendarUnit fromDate:[exdatePicker date]];
[dc setDay:dc.day - 1];
NSDate *noticeDate = [[NSCalendar currentCalendar] dateFromComponents:dc];
NSDateFormatter* dateFormatterstring = [[NSDateFormatter alloc] init];
[dateFormatterstring setDateFormat:#"dd-MM-yyyy hh:mm:ss a"];
NSString *dateString = [dateFormatterstring stringFromDate:noticeDate];
txtExpirayDate.text = dateString;
UILocalNotification *notification = [[cls alloc] init];
notification.fireDate = noticeDate;
notification.timeZone = [NSTimeZone defaultTimeZone];
notification.alertBody = [NSString stringWithFormat:#"%# your Licence Expiry Date is Tommorow",txtLicence.text];
notification.alertAction = #"Show me";
notification.soundName = UILocalNotificationDefaultSoundName;
notification.applicationIconBadgeNumber = 1;
NSDictionary *userDict = [NSDictionary dictionaryWithObject:txtLicence.text forKey:kRemindMeNotificationDataKey];
notification.userInfo = userDict;
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
[notification release];
}
exdatePicker.hidden=YES;
}
do some changes and you got your output
i hope this answer help you...
:)
Remove this line if you want multiple press on button.
[[UIApplication sharedApplication] cancelAllLocalNotifications];
because its removing your all previous notifications.

UILocalNotification isn't working at all
I'm writing an app that sends the user an alert through the Notification Center when an event date is approaching. But when I set the date in the date picker and close the app, the notification doesn't appear. I already enabled Push Notifications in my provisioning profiles. This is all the code in my project that deals with the notification center,This is all the code in my view controller file dealing with the date picker:
- (IBAction)dateChanged:(id)sender
{
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSDate *selectedDate = [self.datePicker date];
[defaults setObject:selectedDate forKey:#"ImportantDatesViewController.selectedDate"];
[defaults synchronize];
}
- (void)viewDidLoad {
NSDate *storedDate = [[NSUserDefaults standardUserDefaults]
objectForKey:#"ImportantDatesViewController.selectedDate"];
if (storedDate == nil) {
storedDate = [NSDate date];
}
[self.datePicker setDate:storedDate animated:NO];
}
And this is everything in my App delegate dealing with local notifications:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
....
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
UIRemoteNotificationTypeBadge |
UIRemoteNotificationTypeAlert |
UIRemoteNotificationTypeSound];
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"mm'/'dd'/'yyyy"];
NSDate *eventDate = [[NSUserDefaults standardUserDefaults] objectForKey:#"ImportantDatesViewController.selectedDate"];
localNotif.fireDate = [eventDate dateByAddingTimeInterval:-13*60*60];
localNotif.timeZone = [NSTimeZone defaultTimeZone];
localNotif.alertBody = #"Event in three days!";
localNotif.alertAction = nil;
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.applicationIconBadgeNumber = 0;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
return YES;
}
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
NSString* pushToken = [[[[deviceToken description]

NSLog(#"%#", pushToken);
}

}
Any help is much appreciated, thank you!
following code is use for the local notification.
-(IBAction)buttonPressed:(UIButton *)button

// Create a payload to go along with the notification
NSArray *array = [NSArray arrayWithObjects:#"Value 1", #"Value 2", nil];
NSDictionary *data = [NSDictionary dictionaryWithObject:array forKey:#"payload"];
[localNotification setUserInfo:data];
if (button == buttonAlert || button == buttonAll)
{
