Local Notifications in iOS without running the app - ios

Question

My application needs to have more than 10 local notifications at different time (not recurring) on daily basis. According to iOS official docs, i can only schedule 64 notifications. I have tried solutions from this and several others articles on the web but found no working solution.
Is there any way i can schedule the Local notifications at different times even if my app is not running for several days (or killed)?

Answer 1

There is no direct way For doing this.
If you want to do it anyhow(not proper solution, just a patch), then just go via following way.
wake up the app in background - which can be done by using starting location manager, which will wake up your app in background when location get updated, at that time you can do whatever you like with local notification or any other things.
Before applying this method - make sure that - this is too much battery consuming way + not proper way. Your app might get rejected from apple if it is using too much battery.
Read following details(copied from other question from stackoverflow):
An app can be woken by a significant location change, if the app has indicated that it wants to monitor such events.
See: [CLLocationManager Docs][1]
Look for a method called startMonitoringSignificantLocationChanges. If a significant location change occurs while your app is not in the foreground or isn't running at all, your application will be launched in the background, allowing the app to perform background-only operations (e.g. no view code will run).

When you want your app to work in background even when it is killed then you have to enable 'Background Modes' from your Project's Capabilities and fire your Local Notifications method with specific times through that.
Here is a little code snippet to get you started:
var backgroundTask: UIBackgroundTaskIdentifier = UIBackgroundTaskInvalid
override public func viewDidLoad() {
super.viewDidLoad()
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.reinstateBackgroundTask), name: UIApplicationDidBecomeActiveNotification, object: nil)
}
//MARK: Background Task / Local Notifications / Checkin
deinit {
NSNotificationCenter.defaultCenter().removeObserver(self)
}
func reinstateBackgroundTask() {
if backgroundTask == UIBackgroundTaskInvalid {
registerBackgroundTask()
}
}
func registerBackgroundTask() {
backgroundTask = UIApplication.sharedApplication().beginBackgroundTaskWithExpirationHandler {
[unowned self] in
self.endBackgroundTask()
}
assert(backgroundTask != UIBackgroundTaskInvalid)
}
func endBackgroundTask() {
NSLog("Background task ended.")
UIApplication.sharedApplication().endBackgroundTask(backgroundTask)
backgroundTask = UIBackgroundTaskInvalid
}
func dosomething() {
registerBackgroundTask()
//Fire Local Notifications accordingly…
//Use NSTimer if you want it with specific time intervals
}
