Removing UILocalNotification from notification tray programmatically
(7 answers)
Closed 8 years ago.
I am using UILocalNotifications in my app.Now my requirement is the local notification should be cancelled after it’s scheduled.
Here my Code…
-(void)LocalNotificationMethod{
NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
// Get the current date
NSDate *pickerDate = self.selectedDate;
NSLog(#" self.selectedDate %#", self.selectedDate);
// 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];
NSLog(#"itemDate %#",itemDate);
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
return;
localNotif.fireDate = itemDate;
NSLog(#"itemDate %#", localNotif.fireDate);
localNotif.timeZone = [NSTimeZone defaultTimeZone];
// Notification details
localNotif.alertBody = [_titleTextFieldObj text];
// Set the action button
localNotif.alertAction = #"View";
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.applicationIconBadgeNumber =[[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
NSLog(#" localNotif.applicationIconBadgeNumber ++ %ld", (long)localNotif.applicationIconBadgeNumber );
// Specify custom data for the notification
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:[_titleTextFieldObj text] forKey:#"someKey"];
localNotif.userInfo = infoDict;
NSArray *notificationArray = [[UIApplication sharedApplication] scheduledLocalNotifications];
//UILocalNotification *notif = [notificationArray objectAtIndex:indexPath.row];
NSLog(#"notif %#",notificationArray);
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
}
**In Appdelegate.m i wrote the code like…**
-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{
application.applicationIconBadgeNumber=1;
if (notification) {
NSLog(#"notify %#",notification);
NSString *custom=[notification.userInfo objectForKey:#"someKey"];
NSLog(#"custom %#",custom);
NSString *newString = [custom stringByReplacingOccurrencesOfString:#" " withString:#""];
NSLog(#"newString %#",newString);
NSLog(#"custmky%#",notification.description);
UIAlertView *alert=[[UIAlertView alloc]initWithTitle:#"Message" message:newString delegate:self cancelButtonTitle:#"OK" otherButtonTitles: nil];
alert.delegate=self;
[alert show];
}
//UIApplication *application = [UIApplication sharedApplication];
NSString *notificationId = #"id_to_cancel";
//UILocalNotification *notification = nil;
for(UILocalNotification *notify in [[UIApplication sharedApplication] scheduledLocalNotifications])
{
if([[notify.userInfo objectForKey:#"someKey"] isEqualToString:notificationId ])
{
notification = notify;
break;
}
}
[[UIApplication sharedApplication] cancelLocalNotification:notification];
}
but it is not going into the loop …
I am new to this concept.Can anyone please help me to resolve this….
Thanks in advance.

Answer 1

You want to cancel a scheduled notification based on receiving another notification, if it is the case you need to put the loop before showing the Alert else your loop will never be executed. or in case you need to cancel/or not notification based button that will be taped in your AlertView you can put that code in your alertView delegate
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if (buttonIndex==0) {
for(UILocalNotification *notify in [[UIApplication sharedApplication] scheduledLocalNotifications]){
if([[notify.userInfo objectForKey:#"someKey"] isEqualToString:#"someValue"]) {
[[UIApplication sharedApplication] cancelLocalNotification:notify];
break;
}
}
}

By Default all UILocalNotification is OneTime so it cancel automatically after its fireDate
And looks like you are trying to get same UILocalNotification.
Please try putting same code at different place you will get all your Scheduled Notifications Or try to get all Scheduled Notifications before fireDate.
