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.

I have an app where I have to use alert view and I know its not possible to set it, so the notification comes in alert view style. How do I set it so that if the user taps that I can they can receive local notifications , it will be automatically set to alert.
you can simply set UILocalNotification with my bellow custom method..
- (void) scheduleAlarm:(NSString *)PaymentTitle FireDate:(NSDate *)tempFireDate {
NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
NSDate *pickerDate = tempFireDate; //Set yourDate here
// 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];//comment it if use ARC
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
return;
localNotif.fireDate = itemDate;
localNotif.timeZone = [NSTimeZone defaultTimeZone];
// Notification details
localNotif.alertBody =#"Write your Message";
// Set the action button
localNotif.alertAction = #"View";
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.applicationIconBadgeNumber = 1;
// Specify custom data for the notification
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:#"iClientManagement" forKey:#"App"];
localNotif.userInfo = infoDict;
// Schedule the notification
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
// [localNotif release];//cxomment it if use ARC
}

I need to get a date and time from a UIDatePicker and fire a local notification when that date and time has arrived. How would I go about doing this? Thanks!
use this code
NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
// Get the current date
NSDate *pickerDate = your date from date picker;
// 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]];
[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
localNotif.alertBody = #"Write your text here";
// Set the action button
localNotif.alertAction = #"View";
localNotif.soundName = UILocalNotificationDefaultSoundName;
// Specify custom data for the notification
NSStream *str=[NSString stringWithFormat:#"%d",cId];
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:str forKey:#"NotificationDate"];
localNotif.userInfo = infoDict;
// Schedule the notification
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
NSLog(#"The notifications are:%#",[[UIApplication sharedApplication]scheduledLocalNotifications]);
NSLog(#"The %#",localNotif.userInfo);
[localNotif release];
Use self.datePicker.date to store the target date with time.
Then make a NSTimer that will poll every miilisecond to check if current date equals to target date. As both become equal then show the alertview.
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.
I am making an iPhone app. In this app I have used tableview which shows local notifications timing whenever I press the datetime picker. Now I want to store all the values of tableview in to an array. How can I do this. Please give me some solutions.
We have implemented the Local notification and uses PickerView for it to set the data on the rows in tableview. This is the code snippet for displaying the data in tableview:- - (IBAction) scheduleAlarm:(id) sender {
[eventText resignFirstResponder];
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
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];
[self.tableview reloadData];
}
I think you should create a custom class and define the all this variables as property. then in
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
method create a new object of that class and assign all these value accordingly. after that in any mutable array add this custom objects. n yes take care of duplications.
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.
