Question

I’m having issues when trying to schedule a UILocalNotification using the following code:

    - (IBAction) createNotification {
    //Just to verify button called the method
    NSLog(@"createNotification");

    NSString *dateString = dateTextField.text;

    NSString *textString = textTextField.text;

    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"MM-dd-yyyy HH:mm"];
    [formatter setTimeZone: [NSTimeZone defaultTimeZone]];

    NSDate *alertTime = [formatter dateFromString:dateString];

    UIApplication *app = [UIApplication sharedApplication];

    UILocalNotification *notification = [[[UILocalNotification alloc] init] autorelease];
    if(notification){
        notification.fireDate = alertTime;
        notification.timeZone = [NSTimeZone defaultTimeZone];
        notification.repeatInterval = 0;
        notification.alertBody = textString;

        [app scheduleLocalNotification:notification];

        NSLog(@"%@", dateString);
    }
}

The code is being called correctly when I press the button and I’m passing in the following date string:

02-12-2012 19:01

• I’ve also tried

02/12/2012 19:01

to no avail. (I change the time accordingly depending on the time of testing e.g. 21:06)

Can someone please explain why the local notification isn’t displaying?

Thanks in advance,

Jack

Answer 1

Local notifications are delivered, but do not display (i.e., no badges, no sounds, no alerts) when the app is running and in the foreground. But the application:didReceiveLocalNotification: method of your app delegate is called, if you need to react to a local notification in some way.

See the UILocalNotification class reference for details.
