I'm trying to log the day but not the date that my notification will fire at.
say I have this code that I need it to fire on Sunday, here is what I tried and what came out after that:
-(void) Sunday { // 9th Notification Every 1:35
NSCalendar *calendar = [NSCalendar currentCalendar];
calendar.timeZone = [NSTimeZone timeZoneWithName:#"GMT"];
NSDateComponents *components = [calendar components:NSWeekCalendarUnit fromDate:[NSDate date]];
components.weekday = 1;
components.hour = 22;
components.minute = 38;
components.second = 25;
NSDate *fire = [calendar dateFromComponents:components];
NSLog(#"The Fire day is:: %#", fire);
UILocalNotification *notif = [[UILocalNotification alloc] init] ;
if (notif == nil)
return;
notif.fireDate = fire;
notif.repeatInterval= NSWeekCalendarUnit ;
notif.soundName = #"ring.wav";
notif.alertBody = [NSString stringWithFormat: #"THANKS for Your HELP :)"] ;
[[UIApplication sharedApplication] scheduleLocalNotification:notif] ;
}
and the log shows:
2014-01-19 22:37:45.470 daily notification test[15595:c07] The Fire day is:: 0001-01-21 22:38:25 +0000
I'm just trying to fire a notification every specific day of the week regardless of the month and the year.. but it only works with me when defining the hour only and using the NSHourCalendarUnit.
I appreciate your help.
It would appear to not be working because you aren't setting the year, so it's defaulting to 0001. Don't just take NSWeekCalendarUnit from the current date, take the year too.

I'm having significant trouble with my iOS local notifications. I have an app, written in Objective-C, that allows the user to pick the time the notification fires, as well as the days of the week (it should fire every week on the specified days at the specified time). I have no trouble with the time of day the notification fires, that works correctly. However, when I specify the day(s) it should fire, odd things happen. At first, they fire once, but every day rather than only the specified days. Then, after the first week, they fire every day, but not only once. Instead, they fire as many times as days are specified (so if Sunday, Monday and Tuesday are chosen, each day, the user will receive 3 consecutive notifications at the specified time).
This is the code I'm using to set up the notifications.
When the "Save" button is tapped, the first thing that happens is a clearing of all notifications, to make way for the new ones.
//cancels all notifications upon save
[[UIApplication sharedApplication] cancelAllLocalNotifications];
Next, I use NSDate, NSCalendar and NSCalendarComponents to get the specifics for the current time, as well as the components from my UIPicker (which is used to select the time of day)
NSDate *now = [NSDate date];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitWeekOfYear|NSCalendarUnitWeekday|NSCalendarUnitHour|NSCalendarUnitMinute fromDate:now];//get the required calendar units
Then, I get the units for the time from the UIPicker, and the actual time, also from the picker.
NSDateComponents *pickedComponents = [calendar components:(NSCalendarUnitHour | NSCalendarUnitMinute) fromDate:picker.date];
NSDate *minuteHour = [calendar dateFromComponents:pickedComponents];
[[NSUserDefaults standardUserDefaults] setObject:minuteHour forKey:#"FireTime"];
After that, I set the text I want to show up in the notification
NSString *reminder = #"Reminder text!";
Next is the actual setup of the notification. They're all the same (with the day of the week changed, of course), so I'll just show the one for Sunday.
//sunday
UILocalNotification *localNotificationSunday = [[UILocalNotification alloc] init];
if ([sundayTempStatus isEqual:#"1"])
{
//permanently save the status
[[NSUserDefaults standardUserDefaults] setObject:#"1" forKey:#"Sunday"];
//set up notifications
//if it is past sunday, push next week
if (components.weekday > 1)
{
components.day = components.day + 7; //if already passed sunday, make it next sunday
}
//components.day = 1;
components.hour = [pickedComponents hour];
components.minute = [pickedComponents minute];
NSDate *fireDate = [calendar dateFromComponents:components];
localNotificationSunday.fireDate = fireDate;
localNotificationSunday.alertBody = reminder;
localNotificationSunday.timeZone = [NSTimeZone systemTimeZone];
localNotificationSunday.repeatInterval = NSCalendarUnitWeekOfYear;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotificationSunday];
}
else
{
[[NSUserDefaults standardUserDefaults] setObject:#"0" forKey:#"Sunday"];
}
Any help is greatly appreciated, and if any additional info or code is needed, I'll gladly provide it.
When code becomes repetitive, it often becomes more error-prone. I've written out a simple method that should take care of the scheduling of the reminders.
- (void)scheduleNotificationForDayOfWeek:(int)dayOfWeek withPickedComponents:(NSDateComponents *)pickedComponents andReminderString:(NSString *)reminderString {
NSCalendar *calendar = [NSCalendar currentCalendar];
UILocalNotification *notification = [[UILocalNotification alloc] init];
NSDateComponents *components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitWeekOfYear|NSCalendarUnitWeekday|NSCalendarUnitHour|NSCalendarUnitMinute fromDate:[NSDate date]];
components.hour = [pickedComponents hour];
components.minute = [pickedComponents minute];
NSDateComponents *additionalComponents = [[NSDateComponents alloc] init]; // to be added onto our date
if ([components weekday] < dayOfWeek) {
additionalComponents.day = (dayOfWeek - [components weekday]); // add the number of days until the next occurance of this weekday
} else if ([components weekday] > dayOfWeek) {
additionalComponents.day = (dayOfWeek - [components weekday] + 7); // add the number of days until the next occurance of this weekday
}
NSDate *fireDate = [calendar dateFromComponents:components];
fireDate = [calendar dateByAddingComponents:additionalComponents toDate:fireDate options:0]; // add on our days
notification.fireDate = fireDate;
notification.alertBody = reminderString;
notification.timeZone = [NSTimeZone systemTimeZone];
notification.repeatInterval = NSCalendarUnitWeekOfYear;
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
}
What this does is actually pretty simple. Call it with a day of the week (e.g., 0 = Sunday, 1 = Monday), and it will schedule a repeating reminder for that day. I couldn't reproduce your issues in my tests with your Sunday code, so I figured that somewhere among repeating that code you must have made an error.
In this method, the fire date getting has been simplified. It uses NSDateComponents to easily get the next occurrence of that weekday. Call it like this: [self scheduleNotificationForDayOfWeek:0 withPickedComponents:pickedComponents andReminderString:#"Hello, world!"]; (which would show "Hello, world!" every Sunday at the specified components)
With this snippet, you should be able to get rid of most of the repeated statements in your code, and simplify how setting notifications is done. For me, this worked perfectly.
I am building an iOS app that makes use of local notifications to remind the user to complete a task, but only on the certain days (chosen by the user). The time at which the notification should fire is set by the date picker. My code is based on some code from another SO post.
Say the user would like to be reminded to complete said task on Sundays. The first thing I do is find out what the current date is, and get the correct components from it, then get the correct components from the date picker for the hour and minute.
//set up calendar and correct components
NSDate *now = [NSDate date];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitWeekOfYear|NSCalendarUnitWeekday|NSCalendarUnitHour|NSCalendarUnitMinute fromDate:now]; //get the required calendar units
NSDateComponents *pickedComponents = [calendar components:(NSCalendarUnitHour | NSCalendarUnitMinute) fromDate:picker.date];
NSDate *minuteHour = [calendar dateFromComponents:pickedComponents];
[[NSUserDefaults standardUserDefaults] setObject:minuteHour forKey:#"FireTime"];
NSString *reminder = #"Don't forget to check which customers are on vacation!";
Next, the data is saved, and the notification set up. This code is the same for every day of the week, with only the day name changed.
When the tempStatus is equal to "1", the user has chosen that day as a day to remind them.
//Save data
//sunday
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
if ([sundayTempStatus isEqual:#"1"])
{
//permanently save the status
[[NSUserDefaults standardUserDefaults] setObject:#"1" forKey:#"Sunday"];
//set up notifications
//if it is past sunday, push next week
if (components.weekday > 1)
{
components.weekOfYear++; //if already passed sunday, make it next sunday
}
components.hour = [pickedComponents hour];
components.minute = [pickedComponents minute];
NSDate *fireDate = [calendar dateFromComponents:components];
localNotification.fireDate = fireDate;
localNotification.alertBody = reminder;
localNotification.timeZone = [NSTimeZone systemTimeZone];
localNotification.repeatInterval = NSCalendarUnitWeekOfYear;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
else
{
[[NSUserDefaults standardUserDefaults] setObject:#"0" forKey:#"Sunday"];
}
Thanks in advance, and I will gladly provide more information and code if necessary.
I am making an alarm application. When I set the alarm the notification fire immediately. I set two schedule notifications functions for alarm. One is for everyday repeat alarm and other is for weekly repeat alarm. My code for everyday repeat alarm is working fine but for weekly repeat alarm , notifications fire immediately and sometimes fire at different day.
Here is code for repeat alarm for weekly basis.
-(void) scheduleLocalNotificationWithWeek:(NSDate *)fireDate
{
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
localNotif.fireDate = calculateAlarmDay;
NSLog(#"%#",localNotif.fireDate);
localNotif.timeZone = [NSTimeZone localTimeZone];
localNotif.alertBody = #"Time to wake Up";
localNotif.alertAction = #"Show me";
localNotif.soundName = #"Tick-tock-sound.mp3";
localNotif.applicationIconBadgeNumber = 1;
localNotif.repeatInterval = NSWeekCalendarUnit;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
}
and here is a code in which I calculate the day on which it fires e.g if user select sunday than it fires on sunday 28-2-2016 and than next sunday 6-3-2016 and so on..
-(void) repeataftersevendays:(int) day
{
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate:[NSDate date]];
NSLog(#"%#",components);
[components setTimeZone:[NSTimeZone localTimeZone]];
[calendar setTimeZone: [NSTimeZone localTimeZone]];
finalValue = 0;
if (weekday == day)
{
finalValue=0;
}
else if (weekday < day)
{
int tempWeekDay = weekday;
while ( tempWeekDay < day )
{
tempWeekDay++;
finalValue++;
NSLog(#"%i",finalValue);
}
}
else
{
int tempDay = day;
while ( weekday >= tempDay )
{
tempDay++;
finalValue++;
}
}
calculateAlarmDay = [calendar dateByAddingUnit:NSCalendarUnitDay
value:finalValue
toDate:[NSDate date]
options:0];;
NSLog(#"value is %#",calculateAlarmDay);
}
I am stuck with this stuff from last seven days. Please tell me the solution. Thanks
I'm working on a feature that will allow users to schedule days and a time for receiving a notification.
So far, the time and message feature is working great. Where I am stuck at is the repeat interval.
Here's what I have tried:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setTimeStyle:NSDateFormatterShortStyle];
NSString *formatedDate = [dateFormatter stringFromDate:self.datePicker.date];
self.currentTimeLabel.text = formatedDate;
NSDate *date = [dateFormatter dateFromString:self.currentTimeLabel.text];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [calendar components:(NSCalendarUnitHour | NSCalendarUnitMinute) fromDate:date];
NSInteger hour = [components hour];
NSInteger minute = [components minute];
[components setHour:hour];
[components setMinute:minute];
if ([self.currentRepeatLabel.text containsString:#"Sun"]) {
[components setWeekday:0];
self.notification = [[UILocalNotification alloc] init];
self.notification.fireDate = [calendar dateFromComponents:components];
self.notification.repeatInterval = NSCalendarUnitDay;
[self.notification setAlertBody:[NSString stringWithFormat:#"A friendly reminder: %#", self.titleStringToDisplay]];
if (self.soundSwitch.isOn == YES) {
self.notification.soundName = #"soundeffect.wav";
}
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:self.titleStringToDisplay forKey:#"title"];
self.notification.userInfo = infoDict;
[[UIApplication sharedApplication] scheduleLocalNotification:self.notification];
}
if ([self.currentRepeatLabel.text containsString:#"Mon"]) {
[components setWeekday:1];
self.notification = [[UILocalNotification alloc] init];
self.notification.fireDate = [calendar dateFromComponents:components];
self.notification.repeatInterval = NSCalendarUnitDay;
[self.notification setAlertBody:[NSString stringWithFormat:#"A friendly reminder: %#", self.titleStringToDisplay]];
if (self.soundSwitch.isOn == YES) {
self.notification.soundName = #"soundeffect.wav";
}
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:self.titleStringToDisplay forKey:#"title"];
self.notification.userInfo = infoDict;
[[UIApplication sharedApplication] scheduleLocalNotification:self.notification];
}
// I'm doing this for each day.
NSCalendarUnitDay is repeating my notification everyday, not matter what days I have selected. I have tried NSCalendarUnitWeekOfYear but my notifications never fire when using that.
The goal is for the user to set their title, time, and repeat days (much like the native alarm app).
How do I set the repeat interval for this?
Update and new issue:
I am using NSCalendarUnitWeekOfYear now.
Here's my issue ... the notification is no longer firing now and the repeatInterval is always set to Monday instead of the day of the week that it steps through in code.
There are several ways to do that . You can use NScalender to find the weekday and than calculate that date on which you want to be notifications fire.
-(void) calculateweeknumber
{
NSCalendar *numberCalendar = [NSCalendar currentCalendar];
NSDateComponents *comps = [numberCalendar components:NSWeekdayCalendarUnit fromDate:[NSDate date]];
[comps setSecond:0.0];
weekday = [comps weekday];
NSLog(#"number is %d",weekday);
}
Your code has many problems.
Your date comes from a UIDatePicker obviously. You should use this date. Converting it back and forth is nonsense.
Also, get rid of all that duplicated code. It makes understanding (and fixing) the code more difficult. It hides the logic.
The real problem though is that you just set date components as if it were a date. It is not. You are starting with some date thrown into components, and then setting a weekday. This will not give another valid date - why should it? How could it? What should it adjust? The day? The month? The year? Into the future or into the past? The weekday seems to be simply ignored when converting to a date.
You need to calculate a proper date (this answer describes calculating the next monday).
- (void)scheduleNotification :(int) rowNo
{
[[UIApplication sharedApplication] cancelAllLocalNotifications];
Class cls = NSClassFromString(#"UILocalNotification");
if (cls != nil) {
UILocalNotification *notif = [[cls alloc] init];
notif.timeZone = [NSTimeZone defaultTimeZone];
NSString *descriptionBody=[[remedyArray objectAtIndex:rowNo]objectForKey:#"RemedyTxtDic"];
NSLog(#"%#",descriptionBody);
notif.alertBody = [NSString stringWithString:descriptionBody];
notif.alertAction = #"Show me";
notif.soundName = UILocalNotificationDefaultSoundName;
notif.applicationIconBadgeNumber = 1;
NSDictionary *userDict = [NSDictionary dictionaryWithObject:notif.alertBody
forKey:#"kRemindMeNotificationDataKey"];
notif.userInfo = userDict;
[[UIApplication sharedApplication] scheduleLocalNotification:notif];
}
}
I have a column name frequency which is fetched from Sqldb where it contains the number of times notification should appear for a particular cell.
if frequency = 3 ..the notification should fire say 8 AM , 2PM then 8PM
if frequency = 4 ..the notification should fire say 8 AM , 12PM , 4PM then 8PM.
Is there a way to do it? If anyone can help me that would be great
Unfortunately, You can specify value for repeatInterval only of type NSCalendarUnit (day, week, month). So, I think, You need to create several Notifications with different fireDate, and specify for them repeatInterval = NSDayCalendarUnit
For example,
NSDate *currentTime = [NSDate date];
notification1.fireDate = [NSDate dateWithTimeInterval:SOME_INTERVAL sinceDate:currentTime];
notification1.repeatInterval = NSDayCalendarUnit;
notification2.fireDate = [NSDate dateWithTimeInterval:SOME_INTERVAL * 2 sinceDate:currentTime];
notification2.repeatInterval = NSDayCalendarUnit;
After user viewed some of notifications - You can cancel them.
Update.
You can also create NSDate from different components like this:
NSDateComponents *components = [[NSDateComponents alloc] init];
[components setWeekday:2]; // Monday
[components setWeekdayOrdinal:1]; // The first Monday in the month
[components setMonth:5]; // May
[components setYear:2013];
NSCalendar *gregorian = [[NSCalendar alloc]
initWithCalendarIdentifier:NSGregorianCalendar];
NSDate *date = [gregorian dateFromComponents:components];
Also You can set hour, minutes, seconds, timezone and other parameters.
