Is there any way to set the volume of LocalNotification in ios.I have wrote this code and it is working perfectly but I am not getting any way to set volume of local notification.The code is as follows:
UILocalNotification *localNotification =[[UILocalNotification alloc]init];
if (localNotification==nil) {
return;
}
localNotification.fireDate=date;
localNotification.timeZone=[NSTimeZone defaultTimeZone];
localNotification.repeatCalendar=[NSCalendar currentCalendar];
localNotification.alertBody=[NSString stringWithFormat:#"%#",[tmpdict objectForKey:#"Reminder"]];
NSDictionary *snoozeDic=[tmpdict objectForKey:#"Snooze"];
if ([[snoozeDic valueForKey:#"Switch"]intValue]==1) {
localNotification.alertAction=#"Snooze";
}else
{
localNotification.hasAction=NO;
}
localNotification.repeatInterval=CalUnit;
localNotification.soundName=[NSString stringWithFormat:#"%#.caf",[tmpdict objectForKey:#"Tone"]];
localNotification.userInfo=[NSDictionary dictionaryWithObject:tmpdict forKey:#"AlarmInfo"];
localNotification.applicationIconBadgeNumber=1;
[[UIApplication sharedApplication]scheduleLocalNotification:localNotification];

how can we set more than one reminder's in our iPhone app, i have to set individual reminder's for every image projects in my app so that a user can take image (daily, weekly or monthly) from the camera for a specific project, i am able to set single reminder but when i tried to set more than one reminder for another project in my app it overwrites all the previous reminders of all projects. please give me any idea.
try this.
//KeyValue = used for identifying reminder
//RepeatType = NSWeekCalendarUnit or NSMonthCalendarUnit
//AlertBody = display text
-(void)setReminder:(NSDate*)date KeyValue:(NSString*)keyValue RepeatType:(NSInteger)repeatType AlertBody:(NSString*)alertBody
{
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
return;
localNotif.fireDate = date;
localNotif.timeZone = [NSTimeZone defaultTimeZone];
// Notification details
localNotif.alertBody = alertBody;
// Set the action button
localNotif.alertAction = NSLocalizedString(#"View",nil);
localNotif.soundName =UILocalNotificationDefaultSoundName;
// Specify custom data for the notification
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:[NSString stringWithFormat:#"%#",keyValue] forKey:#"ReminderID"];
localNotif.userInfo = infoDict;
localNotif.repeatInterval = repeatType;
// Schedule the notification
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
[localNotif release];
}
//call this method for setting single notification.
//you can set as many as you want
I set the "application does not run in background" in my info.plist, so when user tap home button, app quits.
When my [UIApplication -appWillTerminate:] called, I will schedule 64 local notifications to system, all of them are non-repeating.
but that take a seemingly long time(6.17 seconds) on a iPhone4 with iOS6.0.1.
When I look at the time profiler, I found that the curve is very strange, it don't take much CPU time, but it do take a lot of time.
Also when I look at the call tree, 93% of the time is spent on [UIApplication -scheduleLocalNotification:] in the time range showed in the image.
Why?
This is how I generate my notifications:
UILocalNotification *n = [[[UILocalNotification] alloc] init] autorelease];
n.alertBody = #"some body";
n.hasAction = YES;
n.alertAction = #"some action";
n.fireDate = #"some date";
n.repeatInterval = 0;
n.soundName = #"my sound"
n.userInfo = aDictionaryWithAStringAbount10CharacterLongAnd2NSNumber.
[self.notifications addObject:n];
This is how I schedule my notifications:
-(void)endProxyAndWriteToSystemLocalNotification
{
_proxying = NO;
NSDate *dateAnchor = [NSDate date];
NSEnumerator *enumerator = [self.notifications objectEnumerator];
NSInteger i = 0;
while (i < maxLocalNotifCount) {
UILocalNotification *n = [enumerator nextObject];
if (!d) {
break;
}
if ([n.fireDate timeIntervalSinceDate:dateAnchor] >= 0) {
[[UIApplication sharedApplication] scheduleLocalNotification:n];
i++;
}
}
[self.notificationDatas removeAllObjects];
}
This would help:
-(void)endProxyAndWriteToSystemLocalNotification {
[[UIApplication sharedApplication] setScheduledLocalNotifications:self.notifications];
}
iOS 4.2 and later
read UIApplication Class Reference for detailed description
I think the problem is that you are trying to schedule 64 local notifications. Is there a reason to do all of these on app termination? Apples scheduleLocalNotification was not designed to be called so many times on termination
I want to implement local notification in my clock app.Basically i want that a music file should be played after every half an hour like in ship's clock in which chimes are played after every 30 minutes.
Can anyone give rough idea as how i can implement this functionality even when the app enters in background?
I recently used the Local notification stuff and used the following functions
//Setting up the Local Notifications
for (int i= 1 ; i<=10; i++) { //We here set 10 Notification after every 30 minutes from now you can modify it accordingly
NSDate *scheduled = [[NSDate date] dateByAddingTimeInterval:60*30*i]; //These are seconds
NSDictionary* dataDict = [NSDictionary dictionaryWithObjectsAndKeys:scheduled,FIRE_TIME_KEY,#"Background Notification received",NOTIFICATION_MESSAGE_KEY,nil];
[self scheduleNotificationWithItem:dataDict];
}
Where scheduleNotificationWithItem is defined as
- (void)scheduleNotificationWithItem:(NSDictionary*)item {
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
if (localNotification == nil) return;
localNotification.fireDate = [item valueForKey:FIRE_TIME_KEY];
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.alertBody = [NSString stringWithFormat:NSLocalizedString(#"%#", nil), [item valueForKey:NOTIFICATION_MESSAGE_KEY]];
localNotification.alertAction = NSLocalizedString(#"View Details", nil);
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.userInfo = item;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
[localNotification release];
}
Finally you can handle these notifications as
You can handle these notifications as follows
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
// Do the required work you can obtain additional Info via notification.userInfo which happens to be a dictionary
}
reading the developer documentation will help you more to understand the stuff.Hope it helps
You can use UILocalNotifications and set their 'firedate', according to your requirement and then schedule the notification. These notifications doesn't bother whether your app is running or is in background they will always show up like an alertview.
i want that my app will run in the background and do check on somethings.
and if so the local notification will show.
i use this code in the method that check:
UIApplication *app = [UIApplication sharedApplication];
UILocalNotification *notification = [[UILocalNotification alloc] init];
NSArray *oldNotifications = [app scheduledLocalNotifications];
if ([oldNotifications count] > 0) {
[app cancelAllLocalNotifications];
}
if (notification == nil)
return;
NSDate *notificationDate = [NSDate dateWithTimeIntervalSinceNow:10];
notification.fireDate = notificationDate;
notification.timeZone = [NSTimeZone systemTimeZone];
notification.alertBody = #"Test Body";
[app scheduleLocalNotification:notification];
[notification release];
the problem is that when the app is in the foreground it show the alert, but if the app is in the background the notification not show to the screen.
the check that i do is running on uiwebview and reload every 10 seconds, so he need to run in the background too.
Your app won't run in background, except certain cases. Look in to this How to run the application in the background? post.
I have used the code from apples example from this page: Link, but I can't seem to get the sound to repeat. I have checked other applications, such as skype (for VOIP) and Alarm Clock Pro (audio?) but I cannot get the sound file to be repeated.
This is my code:
- (void)applicationDidEnterBackground:(UIApplication *)application
{
AlarmHandler *AHinstance = getAlarmHandlerInstance();
UIApplication* app = [UIApplication sharedApplication];
NSArray *alarmList = [AHinstance getAlarms];
NSArray *oldNotifications = [app scheduledLocalNotifications];
if ([oldNotifications count] > 0)
{
[app cancelAllLocalNotifications];
}
for (Alarm *theAlarm in alarmList) {
NSDate *alarmDate = [theAlarm getNearestActivationDate];
Package *alarmPackage = [theAlarm getAlarmPackage];
NSArray *fileList = [alarmPackage getVoiceFileListForBackgroundNotificationWithHour:theAlarm.larmHour];
if( alarmDate == nil ) continue;
UILocalNotification* alarm = [[[UILocalNotification alloc] init] autorelease];
if (alarm)
{
NSLog(#"File: %#", [fileList objectAtIndex:0]);
alarm.fireDate = alarmDate;
alarm.timeZone = [NSTimeZone defaultTimeZone];
alarm.soundName = [fileList objectAtIndex:0];
alarm.alertBody = #"Time to wake up!";
alarm.repeatInterval = 0;
[app scheduleLocalNotification:alarm];
}
}
}
Any suggestions on how I can fix this?
I have had suggestions to register app as audio player and play sounds in the background, but it seems that apple does take kindly to those applications because they aren't real audio players. Therefore they deny those apps.

There is no way to do this for local notifications. You can either register as a VOIP app or as a "background audio" app, which have separate APIs. However, if you do not provide appropriate functionality to qualify for those kinds of uses, you'll most likely be rejected.
Yes this is possible, as the documentation states:
Your own applications can schedule up to 128 simultaneous notifications, any of which can be configured to repeat at a specified interval
You just need to configure the repeatInterval property:
The calendar interval at which to reschedule the notification.
