App Delegate's application:didReceiveLocalNotification: not called - ios

Question

In my app delegate the method - (void)application:(UIApplication *)application didReceiveLocalNotification: (UILocalNotification *)notification is never called.
This is how I create the notification:
UILocalNotification *notification = [[UILocalNotification alloc] init];
// set UUID, which we will store in userDefaults for later
NSMutableDictionary *myUserInfo = [[NSMutableDictionary alloc] init];
NSString *uuid = [[NSProcessInfo processInfo] globallyUniqueString];
[myUserInfo setValue:uuid forKey:KEY_UUID];
[myUserInfo setValue:#"month" forKey:KEY_UNIT];
[myUserInfo setObject:#YES forKey:KEY_RESCHEDULE];
NSInteger row = [_wurmProphylaxePickerView selectedRowInComponent:0];
switch (row) {
case 0:
[myUserInfo setValue:#2 forKey:KEY_FREQUENCY];
break;
case 1:
[myUserInfo setValue:#4 forKey:KEY_FREQUENCY];
break;
case 2:
[myUserInfo setValue:#6 forKey:KEY_FREQUENCY];
break;
default:
[myUserInfo setValue:#4 forKey:KEY_FREQUENCY];
break;
}
notification.userInfo = myUserInfo;
// calculate date for next notification, depends on the user's selection
NSDate *today = [NSDate date];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *myComps = [[NSDateComponents alloc] init];
[myComps setMinute:1];
notification.fireDate = [calendar dateByAddingComponents:myComps toDate:today options:0];
notification.timeZone = [NSTimeZone localTimeZone];
notification.alertBody = #"My alertBody";
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
And this is in my app delegates, but is never called:
- (void)application:(UIApplication *)application didReceiveLocalNotification: (UILocalNotification *)notification
{
NSDictionary *userInfo = notification.userInfo;
BOOL repeat = [[userInfo objectForKey:KEY_RESCHEDULE] boolValue];
if (repeat)
{
NSInteger frequency = (NSInteger)[userInfo objectForKey:KEY_FREQUENCY];
NSString *unit = (NSString *)[userInfo objectForKey:KEY_UNIT];
NSString *uuid = (NSString *)[userInfo objectForKey:KEY_UUID];
// calculate date for next notification
NSDate *today = [NSDate date];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *myComps = [[NSDateComponents alloc] init];
if ([unit isEqualToString:#"month"]) {
//[myComps setMonth:frequency];
[myComps setMinute:frequency];
} else {
}
// create new notification
UILocalNotification *newNotification = [[UILocalNotification alloc] init];
newNotification.fireDate = [calendar dateByAddingComponents:myComps toDate:today options:0];
newNotification.timeZone = [NSTimeZone localTimeZone];
newNotification.alertAction = notification.alertAction;
newNotification.alertBody = notification.alertBody;
newNotification.userInfo = notification.userInfo;
// schedule it
[[UIApplication sharedApplication] scheduleLocalNotification:newNotification];
}
}
tested on iOS 8, not sure about iOS 7...

If the app is not active when the notification fires, you would handle this in didFinishLaunchingWithOptions as illustrated by this example from the Handling Local and Remote Notifications section of the Local and Push Notifications Programming Guide:
- (BOOL)application:(UIApplication *)app didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UILocalNotification *localNotif =
[launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (localNotif) {
NSString *itemName = [localNotif.userInfo objectForKey:ToDoItemKey];
[viewController displayItem:itemName]; // custom method
app.applicationIconBadgeNumber = localNotif.applicationIconBadgeNumber-1;
}
[window addSubview:viewController.view];
[window makeKeyAndVisible];
return YES;
}
The didReceiveLocalNotification is called if the app was active when the notification fired.
