Notificación local en segundo plano

Question

¿Alguien puede decirme cómo obtener una UILocalNotification mientras mi aplicación está en segundo plano?

Estoy publicando mi código aquí. Gracias por adelantado.

UILocalNotification *localNotif = [[UILocalNotification alloc] init];
if (localNotif == nil)
    return;
localNotif.fireDate =[startDate addTimeInterval:60];
NSLog(@"%@",localNotif.fireDate);

localNotif.timeZone = [NSTimeZone defaultTimeZone];     
localNotif.alertAction = @"View";
localNotif.soundName = UILocalNotificationDefaultSoundName;

NSString *notifStr=[NSString stringWithFormat:@"Hey looks like you''re meeting up with %@, why don''t you let your other friends know what fun they''re missing out on? Share a photo :)",[itemDict objectForKey:@"fname"]];

NSDictionary *infoDict = [NSDictionary dictionaryWithObjectsAndKeys:notifStr ,@"notifKey",nil];
localNotif.userInfo = infoDict;

[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
[localNotif release];

Answer 1

addTimerInterval se depura en iOS 4.0, asegúrese de que su destino de despliegue. Puedes usar.

- (id)dateByAddingTimeInterval:(NSTimeInterval)ti

También asegúrese de establecer el valor correcto para fireDate

-(void)insert:(NSDate *)fire
{
    [[UIApplication sharedApplication]cancelAllLocalNotifications];
    self.localNotification = [[UILocalNotification alloc] init];
    if (self.localNotification == nil)
    {
        return;
    }
    else
    {
        self.localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:60];
        self.localNotification.alertAction = nil;
        self.localNotification.soundName = UILocalNotificationDefaultSoundName;
        self.localNotification.alertBody = @"Hey looks like you''re meeting up with %@, why don''t you let your other friends know what fun they''re missing out on? Share a photo :)";
        self.localNotification.alertAction = NSLocalizedString(@"Read Msg", nil);
        self.localNotification.applicationIconBadgeNumber=1;
        self.localNotification.repeatInterval=0;
        [[UIApplication sharedApplication] scheduleLocalNotification:self.localNotification];
    }
}

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif
{
    [[UIApplication sharedApplication]cancelAllLocalNotifications];
    app.applicationIconBadgeNumber = notif.applicationIconBadgeNumber -1;

    notif.soundName = UILocalNotificationDefaultSoundName;

    [self _showAlert:[NSString stringWithFormat:@"%@",Your msg withTitle:@"Title"];

}

- (void) _showAlert:(NSString*)pushmessage withTitle:(NSString*)title
{
    [self.alertView_local removeFromSuperview];
    self.alertView_local = [[UIAlertView alloc] initWithTitle:title message:pushmessage delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [self.alertView_local show];

    if (self.alertView_local)
    {
    }
}

Espero que esto te ayudará :)

Por favor use el código a continuación.

 self.localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:60];
    self.localNotification.alertAction = nil;
    self.localNotification.soundName = UILocalNotificationDefaultSoundName;
    self.localNotification.alertBody = @"Hey looks like you''re meeting up with %@, why don''t you let your other friends know what fun they''re missing out on? Share a photo :)";
    self.localNotification.alertAction = NSLocalizedString(@"Read Msg", nil);
    self.localNotification.applicationIconBadgeNumber=1;
    self.localNotification.repeatInterval=0;
