didReceivelocalNotification is never called - ios

Question

I am tired of doing this. Let me tell you whats happening. I am using iOS 9.0 & Xcode 7.3.1.
Situation 1 :
I have registered for local notification settings in didFinishLaunchingWithOptions like this.
let settings = UIUserNotificationSettings(forTypes: [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound] , categories: nil)
application.registerUserNotificationSettings(settings)
I have several controllers in my project, user will be pressing one button in one of these and I will be scheduling a notification by calling a function in App Delegate. The function is given below.
func activatingUserLocalNotification(timeIntervalSinceNow : NSDate?, alertBody : String, userInfo : [NSObject : AnyObject], region : CLRegion?)
{
let localNotification = UILocalNotification()
localNotification.fireDate = timeIntervalSinceNow
localNotification.timeZone = NSTimeZone.defaultTimeZone()
localNotification.alertBody = alertBody
localNotification.region = region
localNotification.regionTriggersOnce = false
localNotification.soundName = UILocalNotificationDefaultSoundName
localNotification.userInfo = userInfo
localNotification.applicationIconBadgeNumber = UIApplication.sharedApplication().applicationIconBadgeNumber + 1
UIApplication.sharedApplication().scheduleLocalNotification(localNotification)
}
Now I have set a notification by pressing on a button, which called this above function it successfully scheduled the notification.
I have set breakpoints in all these methods.
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
// Break Point
return true
}
func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forLocalNotification notification: UILocalNotification, withResponseInfo responseInfo: [NSObject : AnyObject], completionHandler: () -> Void) {
// Break Point
}
func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forLocalNotification notification: UILocalNotification, completionHandler: () -> Void) {
// Break Point
}
func application(application: UIApplication, didReceivelocalNotification notification: UILocalNotification)
{
// Break Point
}
And waited for sometime while the app is in Foreground, Waited some more time. Nothing happened. I thought the app would fire up the notification and one of the method would get called, so that I could present the notification inside the app. But nothing happened.
Situation 2 :
Now I have tried the same, now I minimised the app [ App is in Background state ] by going to an another app and using it for sometime. Now the notification fired up properly, just like I have told you I have set breakpoints in almost all methods but none of them called when I clicked on the notification. But it called applicationWillEnterForeground, What am gonna do with this method without the launchOptions.
It's been two days I am fighting with this, Don't have any idea about whats happening.
Push Notifications Works Fine Though [ Inside & Outside the App ].
Let me know your thoughts? Please.
How I call this function activatingUserLocalNotification from a controller.
func setLocalNotificationForDistance(id : String, name : String, location : CLLocationCoordinate2D, radius : Double)
{
let alertBody = "Hello \(name)"
let dict : [NSObject : AnyObject] = ["aps" : ["alert" : alertBody], “id” : id]
let region = CLCircularRegion(center: location, radius: radius, identifier: id)
let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
appDelegate.activatingUserLocalNotification(nil, alertBody: alertBody, userInfo: dict, region: region)
}

Answer 1

This is a bit funny, but change:
func application(application: UIApplication, didReceivelocalNotification notification: UILocalNotification)
To:
func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification)
Note the capital L. From docs:
Also: expect this delegate method to be called only when your app is active. No notification should be visible in that situation as your app is active. You can handle it by using didReceiveLocalNotification delegate method.
