Detect if app is not opened via push notification in iOS? - ios

Question

I took this solution from another stack overflow post to detect if the app is opened via push notification:
func application(_ application: UIApplication, didReceiveRemoteNotification data: [AnyHashable : Any]) {
print("Push notification received: \(data)")
if #available(iOS 9, *) {
if let type = data["type"] as? String, type == "status" {
// IF the wakeTime is less than 1/10 of a second, then we got here by tapping a notification
if application.applicationState != UIApplicationState.background && NSDate().timeIntervalSince(wakeTime as Date) < 0.1 {
// User Tap on notification Started the App
sendPushStatistic()
}
else {
// DO stuff here if you ONLY want it to happen when the push arrives
}
}
else {
}
}
}
Now i wonder how to find out if the app was opened (cold start and from background) without clicking on a push notification but via app icon or from the running apps view?

One way to do this would be to add a boolean in your above function that states if it was opened by push notification.
Then in your viewdidLoad you can check the value of this boolean.
func application(_ application: UIApplication, didReceiveRemoteNotification data: [AnyHashable : Any]) {
print("Push notification received: \(data)")
if #available(iOS 9, *) {
if let type = data["type"] as? String, type == "status" {
// IF the wakeTime is less than 1/10 of a second, then we got here by tapping a notification
if application.applicationState != UIApplicationState.background && NSDate().timeIntervalSince(wakeTime as Date) < 0.1 {
// User Tap on notification Started the App
sendPushStatistic()
} else {
pushNotificationLaunch = true
}
}
}
}
Then in the viewDidLoad function you can create an if statement to see if the created variable is true.
override func viewDidLoad() {
super.viewDidLoad()
if pushNotifcationLaunch = false {
//Code for did launched via app click.
}
}
