In my app i want to set up a local notification on everyday at a particular time.Time is the one that selected from a Time picker.Is there any method for this.Plese help me.
Just specify the firedate as the date from your UIDatePicker and NSDayCalendarUnit as the repeatinterval:
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
return;
localNotif.fireDate = datePicker.date;
localNotif.timeZone = [NSTimeZone defaultTimeZone];
localNotif.alertBody = #"This is the Alert-Body Text"];
localNotif.alertAction = #"Button-Text";
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.applicationIconBadgeNumber = 1;
localNotif.repeatInterval = NSDayCalendarUnit;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
[localNotif release];
you can set Local Notifications.
Right out of apple's sample code:
- (void)scheduleNotificationWithItem:(ToDoItem *)item interval:(int)minutesBefore {
NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
NSDateComponents *dateComps = [[NSDateComponents alloc] init];
[dateComps setDay:item.day];
[dateComps setMonth:item.month];
[dateComps setYear:item.year];
[dateComps setHour:item.hour];
[dateComps setMinute:item.minute];
NSDate *itemDate = [calendar dateFromComponents:dateComps];
[dateComps release];
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
return;
localNotif.fireDate = [itemDate addTimeInterval:-(minutesBefore*60)];
localNotif.timeZone = [NSTimeZone defaultTimeZone];
localNotif.alertBody = [NSString stringWithFormat:NSLocalizedString(#"%# in %i minutes.", nil),
item.eventName, minutesBefore];
localNotif.alertAction = NSLocalizedString(#"View Details", nil);
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.applicationIconBadgeNumber = 1;
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:item.eventName forKey:ToDoItemKey];
localNotif.userInfo = infoDict;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
[localNotif release];
}
you can set a local notification for a specific timstamp.
you have to check userinfo dictionary in applicationDidFinishedLaunching for any notification data.
you have to handle:
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification

I want to make local notification that notify user 5 times a day and repeat them daily,
I have them in a mutable array which object is "hh:mm" which hours and minutes are fixed for GMT+3 town, so I get the current date and find the interval then create a date for the notification
that's the method I implement.
-first applying time zone,
-second if the time before current time so make it for the next day.
-third set local notification for that date.
plz help me

I wanted to have two local notification ,both have different time ,let say my first notification will give alert after 1 minute and the second will give alert after 2 minutes.
I have tried it to create two in appDelegate but only first one is giving me the notification and not the second one .
How can I achieve this ?
Yes It is Possible to set two LocalNotification in any iOS Application
See below method by which you can set multiple LocalNotifications
You just Need to pass required parameter to this method.
- (void)setAlarmFor:(NSArray*)datesArray forTime:(NSString*)atTime notificationName:(NSString*)name
{
for(int dayIndex=0;dayIndex <[datesArray count];dayIndex++)
{
Class cls = NSClassFromString(#"UILocalNotification");//
if (cls != nil) {
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:#"en_US_POSIX"] autorelease]];
NSString* dateStr=[datesArray objectAtIndex:dayIndex];
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
NSDate *tempDate = [dateFormatter dateFromString:dateStr];
NSString *tempString = [dateFormatter stringFromDate:tempDate];
tempString = [NSString stringWithFormat:#"%# %#",tempString,atTime];
[dateFormatter setDateFormat:#"yyyy-MM-dd hh:mm a"];
NSDate *firetAtThisDate = [dateFormatter dateFromString:tempString];
UILocalNotification *localNotif = [[cls alloc] init];
localNotif.fireDate =firetAtThisDate;//here set the Date at which mnotification fire;
NSLog(#"Notification date is:%#",firetAtThisDate);
localNotif.alertBody =name;
localNotif.alertAction = #"Your'Alert message";
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.applicationIconBadgeNumber = 1;
localNotif.timeZone = [NSTimeZone defaultTimeZone];
NSDictionary *userDict = [NSDictionary dictionaryWithObject:tempString
forKey:tempString];//by using this we can further cancel the Notification
localNotif.userInfo = userDict;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
[localNotif release];
[dateFormatter release];
}
}
}
And In Appdelegate Class Prepare Action what you want as Notification Fire
//This Below Line will goes to the Appdelegate DidFinishLaunching Method
Class cls = NSClassFromString(#"UILocalNotification");
if (cls)
{
UILocalNotification *notification = [launchOptions objectForKey:
UIApplicationLaunchOptionsLocalNotificationKey];
if (notification)
{
//do what you want
}
}
application.applicationIconBadgeNumber = 0;
//End of Appdelegate DidFinishLaunching Method.
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
application.applicationIconBadgeNumber = 0;
//do what you want
}
sure , you use one or more local notifications in your app. try this code in your project
-(void) setLocalNotification
{
NSTimeInterval todayTimeIntervel=[[NSDate date]timeIntervalSince1970];
NSTimeInterval nextOneMinTimeIntervel;
nextOneMinTimeIntervel = todayTimeIntervel + 60 ;
NSTimeInterval nexttwoMinTimeIntervel;
nexttwoMinTimeIntervel = todayTimeIntervel + 60*3;
NSDate *date1 = [NSDate dateWithTimeIntervalSince1970:nextOneMinTimeIntervel];
NSDate *date2 = [NSDate dateWithTimeIntervalSince1970:nexttwoMinTimeIntervel];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"yyyy-MM-dd hh:mm a"];
NSString *strDate1 = [dateFormat stringFromDate:date1];
NSString *strDate2 = [dateFormat stringFromDate:date2];
NSArray *arr = [NSArray arrayWithObjects:strDate1,strDate2, nil];
NSArray *titleArr = [NSArray arrayWithObjects:#"First LocalNotification",#"Second LocalNotification", nil];
for (int i =0; i < 2; i++)
{
NSMutableDictionary *dic=[NSMutableDictionary dictionaryWithObjectsAndKeys:[arr objectAtIndex:i],#"dateStr",[titleArr objectAtIndex:i],#"title", nil];
[self scheduleLocalNotification:dic];
}
}
-(void) scheduleLocalNotification:(NSMutableDictionary*) dic
{
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"yyyy-MM-dd hh:mm a"];
NSLog(#"%#", [dateFormat dateFromString:[dic objectForKey:#"dateStr"]]);
localNotif.fireDate = [dateFormat dateFromString:[dic objectForKey:#"dateStr"]];
localNotif.timeZone = [NSTimeZone systemTimeZone];
localNotif.alertAction = #"View";
localNotif.alertBody = [dic objectForKey:#"title"];
localNotif.userInfo = dic;
NSLog(#"value of infoDic %#",dic);
localNotif.repeatInterval = NSDayCalendarUnit;
// Schedule the notification
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
}
// get app instance
UIApplication *app = [UIApplication sharedApplication];
// create local notif
UILocalNotification *notification = [[[UILocalNotification alloc] init] autorelease];
if (notification) {
NSDate *oneMinuteFromNow = [[NSDate date] dateByAddingTimeInterval:60];
notification.fireDate = oneMinuteFromNow;
notification.timeZone = [NSTimeZone defaultTimeZone];
NSString *notificationMessage = #"First";
notification.alertBody = notificationMessage;
notification.soundName = UILocalNotificationDefaultSoundName;
// schedule notification
[app scheduleLocalNotification:notification];
// fire notification right away
[app presentLocalNotificationNow:notification];
}
UILocalNotification *notification1 = [[[UILocalNotification alloc] init] autorelease];
if (notification1) {
NSDate *oneMinuteFromNow1 = [[NSDate date] dateByAddingTimeInterval:120];
notification1.fireDate = oneMinuteFromNow1;
notification1.timeZone = [NSTimeZone defaultTimeZone];
NSString *notificationMessage1 = #"Second";
notification1.alertBody = notificationMessage1;
notification1.soundName = UILocalNotificationDefaultSoundName;
// schedule notification
[app scheduleLocalNotification:notification1];
// fire notification right away
[app presentLocalNotificationNow:notification1];
}
By writing this you ll get one notification after 1min and second one after 2 min. In "didReceiveLocalNotification" method you can check the notification type and can show alert msg.
Hope this will help you.
Yes you can use the multiple local notification in your application.
Check this link.
Hope it helpfull for you
I want to fire a notification before 2 days from targeted date.Currently I am using below code to fire notification but there how to fire notification exactly before 2 days from targeted date.
NSString *frstdate = [[calenderarray objectAtIndex:k] objectForKey:#"date"];
NSLog(#"frstdate..%#",frstdate);
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"yyyy-MM-dd"];
NSDate *date = [dateFormat dateFromString:frstdate];
NSLog(#"date..%#",date);
NSDate *dateToFire = [[[NSDate alloc] initWithTimeInterval:-24*60*60 sinceDate:date]autorelease];
NSLog(#"dateToFire..%#",dateToFire);
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
return;
localNotif.fireDate = itemDate;
localNotif.alertAction = #"View";
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.applicationIconBadgeNumber = 1;
localNotif.userInfo = [NSDictionary dictionaryWithObjectsAndKeys:[NSString stringWithFormat:#"Get Food"], #"foodItem", nil] ;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
[localNotif release];
Thanks in advance.
You should use NSCalendar and NSDateComponents to do the maths - something like:
NSCalendar* calendar = [NSCalendar currentCalendar];
NSDateComponents* twoDaysAgo = [[NSDateComponents alloc] init];
twoDaysAgo.day = -2;
NSDate* dateToFire = [calendar dateByAddingComponents:twoDaysAgo toDate:date options:0];
You can do arithmetic with calendar dates (year/month/day/hour... representation in a given timezone) via the NSCalendar class. Although in most cases, "24*60*60" seconds will be one day -- users probably won't notice the difference.
Do you know how to play an alarm sound when the iPhone is sleeping,
like the built-in Clock app in iPhone?
VERY IMPORTANT EDIT:
in the built-in Clock app in iPhone
when the alarm sound is playing, if user switch the Silent switch to Silent (Vibrate mode),
the alarm sound still continue to play.
Do you know how to do the same?
this code will help you to play music in background:
the sound file of the music should be only 30 sec
notification support 30 sec sound file and it should be in the bundle folder if it is in the document folder then you have to put the path of the sound file
NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
NSString *dateValueRemaining =[NSString stringWithFormat:#"23/08/2012 11:30:33"];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"dd/MM/yyyy HH:mm:ss"];
NSDate *dateRemaining = [dateFormat dateFromString:dateValueRemaining];
NSDate *pickerDate = dateRemaining;
NSDateComponents *dateComponents = [calendar components:(NSYearCalendarUnit
| NSMonthCalendarUnit
| NSDayCalendarUnit)
fromDate:pickerDate];
NSDateComponents *timeComponents = [calendar components:(NSHourCalendarUnit
| NSMinuteCalendarUnit
| NSSecondCalendarUnit)
fromDate:pickerDate];
// Set up the fire time
NSDateComponents *dateComps = [[NSDateComponents alloc] init];
[dateComps setDay:[dateComponents day]];
[dateComps setMonth:[dateComponents month]];
[dateComps setYear:[dateComponents year]];
[dateComps setHour:[timeComponents hour]];
[dateComps setMinute:[timeComponents minute]];
[dateComps setSecond:[timeComponents second]];
NSDate *itemDate = [calendar dateFromComponents:dateComps];
NSLog(#"itemDate: %#", itemDate);
if (localNotif) {
[[UIApplication sharedApplication] cancelLocalNotification:localNotif];
}
localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil) {
return;
}
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
localNotif.fireDate = itemDate;
localNotif.timeZone = [NSTimeZone defaultTimeZone];
localNotif.alertBody = #"Your Time is Over";
localNotif.alertAction = #"View";
//---THIS SONG FILE IN THE NSBUNDLE FOLDER---------//
localNotif.soundName = #"s1.mp3";
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:#"someValue" forKey:#"someKey"];
localNotif.userInfo = infoDict;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
The set button is wired up to run a method called scheduleNotification in the view controller which uses the UILocalNotification class to schedule a notification. The code looks as follows:
(void)scheduleNotification
{
[reminderText resignFirstResponder];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
Class cls = NSClassFromString(#"UILocalNotification");
if (cls != nil)
{
UILocalNotification *notif = [[cls alloc] init];
notif.fireDate = [datePicker date];
notif.timeZone = [NSTimeZone defaultTimeZone];
notif.alertBody = #"Did you forget something?";
notif.alertAction = #"Show me";
notif.soundName = UILocalNotificationDefaultSoundName;
notif.applicationIconBadgeNumber = 1;
NSDictionary *userDict = [NSDictionary dictionaryWithObject:reminderText.text
forKey:kRemindMeNotificationDataKey];
notif.userInfo = userDict;
[[UIApplication sharedApplication] scheduleLocalNotification:notif];
[notif release];
}
}
Before the app enters the background, play a silent sound with AVAudioPlayer and keep it play infinite number of times. And when your notification kicks in, again use AVAudioPlayer to play your notification sound, not the UILocalNotification object. It worked for me.
So looking at i-qi app, most likely they've set their UIBackgroundModes to "audio" in their info.plist. This means that they're able to play audio in the background. They're probably playing silent audio until the timer ends because background audio sessions will get cut if they're not in use.
In terms of the silent switch, thats probably based on the session category they're using. Check out this resource:
http://developer.apple.com/library/ios/#documentation/Audio/Conceptual/AudioSessionProgrammingGuide/AudioSessionCategories/AudioSessionCategories.html#//apple_ref/doc/uid/TP40007875-CH4-SW1
Only method is to use local Notifications or Push notifications..both allow sounds to be played for 30 seconds
Programmers, I am new to objective C.
I am working on local notifications task and my task is that when user quits the applications and he doesn't run application again, suppose for one day, then the app icon badge number should auto increment to one. If it doesn't run for 48 hours, then it should increment and become 2 (means I have to repeat notification) and so on.
I am using local notifications for that. This how I am doing it:
- (void)applicationWillResignActive:(UIApplication *)application
{
[self launchNotification];
}
-(void)launchNotification
{
NSDate *todaydate = [NSDate date];
NSDate *firedates = [todaydate dateByAddingTimeInterval:10.0];
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
return;
localNotif.fireDate = firedates;
localNotif.timeZone = [NSTimeZone defaultTimeZone];
NSDateComponents *dateComps = [[NSDateComponents alloc] init];
NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
NSDateComponents *timeComponents = [calendar components:( NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit)
fromDate:firedates];
[dateComps setHour:[timeComponents hour]];
[dateComps setMinute:[timeComponents minute]];
[dateComps setSecond:[timeComponents second]+10];
localNotif.repeatInterval = NSSecondCalendarUnit;
localNotif.soundName = UILocalNotificationDefaultSoundName;
// Specify custom data for the notification
//NSDictionary *infoDict = [NSDictionary dictionaryWithObject:#"someValue" forKey:#"someKey"];
//localNotif.userInfo = infoDict;
// Schedule the notification
localNotif.applicationIconBadgeNumber = +1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
[localNotif release];
}
I am working from long time and finding no way out.
