Application delegate event(ex.: applicationWillTerminate) to my custom class

Question

I am creating one application where I have created my custom static class where I want to catch application level events like (applicationDidBecomeActive, applicationWillResignActive and applicationWillTerminate).

Say Ex: I want to set one variable in my custom class called : IS_ACTIVE, which is default false

class CustomClass {
    static var IS_ACTIVE: Bool = false;
}

I want to set IS_ACTIVE to true when applicationDidBecomeActive event occurs,

right now I am setting up IS_ACTIVE via "AppDelegate.swift" file where applicationDidBecomeActive occurs,

but I want is applicationDidBecomeActive should occur in my custom class.

please help me on this. Thanks

Hi @rmaddy, It's not duplicate or same as you mentioned. because I do not want to integrate with view controller. I want to catch that event in simple custom class( which is not any controller. ) — Ankur Patel, May 09 '18 at 04:21
A view controller is just an example of another class. It's still the same question and solution. — rmaddy, May 09 '18 at 04:25
Not without setting your attempted code. I suggest posting a new question with your attempt to listen and respond to the notification. — rmaddy, May 09 '18 at 04:29

As my knowledge, you should add observer to listen app event look like this

NotificationCenter.default.addObserver(self, selector: #selector(self.appBecomeActive), name: NSNotification.Name.UIApplicationDidBecomeActive, object: nil)

And remember remove observer when your class deinit

Hi @baohung02, Thanks I tried your suggestion but not working as I am expecting. I thought this only works with controller class not custom class. – Ankur Patel May 09 '18 at 04:25
ok, default is always better :p – baohung02 May 09 '18 at 06:29
