UILocalNotification won't fire - iphone

Question

I'm writing an alarm clock iOS app. It's my first time using UILocalNotification. I'm getting the date from a date picker. I've formatted the dates to check whether my function was being passed the proper date, it was. I checked all of the needed properties for a UILocalNotification and I have them all and my notification still won't fire. Any ideas as to why? Thanks for the help.
#import "BIDAlarmViewController.h"
#interface BIDAlarmViewController ()
#end
#implementation BIDAlarmViewController
#synthesize datePicker;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib
}
- (void)didReceiveMemoryWarning{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(IBAction)setReminderUsingDateFromDatePicker: (id)sender{
[self scheduleNotificationForDate: datePicker.date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd 'at' HH:mm"];
NSString *formattedDateString = [dateFormatter stringFromDate:datePicker.date];
NSLog(#"Button Pressed.. date: %#", formattedDateString);
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Alarm activated"
message:#"Alarm has been set"
delegate:self cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
-(void) scheduleNotificationForDate: (NSDate*)date {
UILocalNotification *alarm = [[UILocalNotification alloc] init];
if (alarm) {
alarm.fireDate = date;
alarm.timeZone = [NSTimeZone defaultTimeZone];
alarm.repeatInterval = 0;
alarm.soundName = #"alarmsound.caf";
alarm.alertBody = #"Test message...";
[[UIApplication sharedApplication] scheduleLocalNotification:alarm];
}
}
#end

http://developer.apple.com/library/ios/documentation/uikit/reference/UIApplicationDelegate_Protocol/Reference/Reference.html#//apple_ref/occ/intfm/UIApplicationDelegate/application:didReceiveLocalNotification:
Make sure you've implemented the referenced method in your app delegate like so:
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
NSLog(#"Notification fired"!);
}
Notes from Apple on implementing this method:
Local notifications are similar to remote push notifications, but
differ in that they are scheduled, displayed, and received entirely on
the same device. An application can create and schedule a local
notification, and the operating system then delivers it at the
schedule date and time. If it delivers it when the application is not
active in the foreground, it displays an alert, badges the application
icon, or plays a sound—whatever is specified in the
UILocalNotification object. If the application is running in the
foreground, there is no alert, badging, or sound; instead, the
application:didReceiveLocalNotification: method is called if the
delegate implements it.
The delegate can implement this method if it wants to be notified that
a local notification occurred. For example, if the application is a
calendar application, it can enumerate its list of calendar events to
determine which ones have due dates that have transpired or are about
to transpire soon. It can also reset the application icon badge
number, and it can access any custom data in the local-notification
object’s userInfo dictionary.
