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.

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
I'm creating a reminder app.In that a local notification is firing at particular time.I'm also implementineg a function for switching ON/OFF the notification.Notification is working fine but cancel function is not working.I'm using the below code.Is there any thing wrong in this code.Please help me.Thanks in advance.
-(void)swit
{
if (flag==1) {
//if (toggleSwitch.on) {
toggleSwitch.on=YES;
flag=1;
NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
// Get the current date
NSDate *pickerDate = [self.datePicker date];
// Break the date up into components
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]];
// Notification will fire in one minute
[dateComps setMinute:[timeComponents minute]];
[dateComps setSecond:[timeComponents second]];
NSDate *itemDate = [calendar dateFromComponents:dateComps];
[dateComps release];
if (localNotif == nil)
return;
localNotif.fireDate = itemDate;
NSLog(#"%#",itemDate);
localNotif.timeZone = [NSTimeZone defaultTimeZone];
// Notification details
localNotif.alertBody = #"Tip of the day";
// 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];
NSLog(#"it is working");
}
else {
toggleSwitch.on=NO;
[[UIApplication sharedApplication] cancelLocalNotification:localNotif];
NSLog(#"it is not working");
}
}
The reason why the notification gets never cancelled if due to your flag var :
// so if flag == 1
if (flag==1) {
toggleSwitch.on=YES;
// the value doesn't change
// you will never reach the else part
flag=1;
When you detect flag==1, assign it another value, so the next time your notification will be cancelled. Also don't forget in the else part, to put flag back to 1.
In my i'm using a action sheet picker view. It is working fine. But I want to fire a local notification when a particular time is set in time picker, it is not firing the local notification. I used this code:
enter code here
- (void)actionPickerDone {
if (nil != self.data) {
//send data picker message[self.target performSelector:self.action withObject:[NSNumbernumberWithInt:self.selectedIndex]];
}
else {
//send date picker message
NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
// Get the current date
NSDate *pickerDate = [self.datePicker date];
// Break the date up into components
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]];
// Notification will fire in one minute
[dateComps setMinute:[timeComponents minute]];
[dateComps setSecond:[timeComponents second]];
NSDate *itemDate = [calendar dateFromComponents:dateComps];
[dateComps release];
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
return;
localNotif.fireDate = itemDate;
NSLog(#"%#what is this",itemDate);
localNotif.timeZone = [NSTimeZone defaultTimeZone];
NSLog(#"i8i8i88i");
// Notification details
//localNotif.alertBody = [eventText text];
// 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];
[localNotif release];
}
Is there any thing wrong in this code.please help me.
I executed your code and the notification didnt fire. Then I uncommented the localNotif.alertBody assignment statement and it did fire. Local notification will not appear as an alert if you do not specify an alertBody. Plus the point raised by Idan is also valid. If your app is in foreground the notif wont be displayed rather you will get a callback in your app delegate in which you should display an alert with the message notification.alertBody for consistency.
Hope this helps :)
PS you dont need all the calender components thing youre doing. Log both of them and youll see that both pickerDate and itemDate are same.
This may be a repeated question,but please help me.I used the code below for firing a local notifification,but it is not firing.I used a picker to set the time for firing the local notification.Please help me..
[self.actionSheet dismissWithClickedButtonIndex:0 animated:YES];
if (nil != self.data) {
//send data picker message
[self.target performSelector:self.action withObject:[NSNumber numberWithInt:self.selectedIndex]];
}
else {
//NSDate *date = [NSDate date];
//NSDateFormatter *dateFormat = [[NSDateFormatter alloc]init];
//[dateFormat setDateFormat:#"HH:mm:ss zzz"];
//NSString *dateString = [dateFormat stringFromDate:date];
//send date picker message
NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
// Get the current date
NSDate *pickerDate = [self.datePickerView date];
//NSLog(#"date ==%#",pickerdate);
//Break the date up into components
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]];
//NSLog(#"day%#",[dateComponents day]);
// Notification will fire in one minute
[dateComps setMinute:[timeComponents minute]];
[dateComps setSecond:[timeComponents second]];
NSDate *itemDate = [calendar dateFromComponents:dateComps];
[dateComps release];
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
return;
localNotif.fireDate = itemDate;
NSLog(#"%#what is this",itemDate);
localNotif.timeZone = [NSTimeZone defaultTimeZone];
//Notification details
localNotif.alertBody = #"Tip of the day";
//Set the action button
localNotif.alertAction = #"View";
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.repeatInterval = NSDayCalendarUnit;
localNotif.applicationIconBadgeNumber = 1;
// Specify custom data for the notification
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:#"someValue" forKey:#"someKey"];
localNotif.userInfo = infoDict;
// Schedule the notification
[localNotif release];
}
Where is the code for scheduling the local notification?
You have to make this call somewhere before you release your UILocalNotification object:
- (void)scheduleLocalNotification:(UILocalNotification *)notification
Like so,
[[UIApplication sharedApplication] scheduleLocalNotification: localNotif];
Its only after you call this method that your notification gets copied, and hence safe for releasing the notification object.
In my universal application I m using the below code for UILocalNotification
NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
// Get the current date
NSDate *pickerDate = [self.datePicker date];
// Break the date up into components
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]];
// Notification will fire in one minute
[dateComps setMinute:[timeComponents minute]];
[dateComps setSecond:[timeComponents second]];
NSDate *itemDate = [calendar dateFromComponents:dateComps];
[dateComps release];
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
return;
localNotif.fireDate = itemDate;
localNotif.timeZone = [NSTimeZone defaultTimeZone];
// Notification details
NSString *str = [txtfield_MyPills.text stringByAppendingString:#" "];
NSString *str_Dosage = [txtfield_Dosage.text stringByAppendingString:#" "];
NSString *str_Frequency = [txtfield_Frequency.text stringByAppendingString:#" "];
NSString *str1 = [str stringByAppendingString:str_Dosage];
NSString *strResult = [str1 stringByAppendingString:str_Frequency];
localNotif.alertBody =strResult;;// [txtfield_MyPills text];//[eventText text];
// 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];
[localNotif release];
Its workin fine in iphone but if I run my application for iPad it shows that UilOcation is undeclared?
Please help me out and If u have sample code for UILocalNotification for iPad please give link for that
Thanks in Advance
not available in 3.2 iOS
http://developer.apple.com/iphone/library/documentation/iphone/Reference/UILocalNotification_Class/Reference/Reference.html
only available in 4.0 or later
As Aron said Uiloaclnotifications are not available in 3.2.
As you might know the new version of iOs for iPad is coming very soon.
Asoming that it will take time until all users will upgrade you can do that -
Try this-
Class notifs = (NSClassFromString(#"UILocalNotification));
If (notifs != nil){
//the notification code here
}
I was informed by apple support that you can test that only on real devices that run 3.2 and not on the simulator.
You can look here in the mail composer code example at apple to see how they implemented that:
https://developer.apple.com/iphone/library/iPad/index.html#samplecode/MailComposer/Listings/Classes_MailComposerViewController_m.html
Hope it will help
