Displaying Viewcontroller based on Notification payload swift - ios

Question

I am getting a push notification and displaying a viewcontroller based on the content of the notification.When the notification is triggered manually from postman, I get the following userInfo
[AnyHashable("google.c.a.e"): 1, AnyHashable("gcm.notification.type"): new_property, AnyHashable("gcm.notification.meta"): {"property_id":"3"}, AnyHashable("gcm.message_id"): 1570614460795417, AnyHashable("aps"): {
alert = {
body = "A new property has been published is in your area";
title = "New Property";
};
}]
// CASTING AS [String: Any]
["google.c.a.e": 1, "gcm.notification.meta": {"property_id":"3"}, "gcm.notification.type": new_property, "aps": {
alert = {
body = "A new property has been published is in your area";
title = "New Property";
};
}, "gcm.message_id": 1570614460795417]
This in turn works and displays the required screen. But when ever a user action triggers the same notification, I get this userInfo
[AnyHashable("gcm.notification.meta"): {"property_id":46}, AnyHashable("gcm.notification.type"): new_property, AnyHashable("body"): A new property has just been listed in your area by Ebenezer Kilani, AnyHashable("title"): New property Listing, AnyHashable("type"): new_property, AnyHashable("meta"): {"property_id":46}, AnyHashable("aps"): {
alert = {
body = "A new property has just been listed in your area by Ebenezer Kilani";
title = "New property Listing";
};
}, AnyHashable("gcm.message_id"): 1570550088749025, AnyHashable("google.c.a.e"): 1]
// CASTING AS [String: Any]
["meta": {"property_id":46}, "type": new_property, "title": New property Listing, "gcm.message_id": 1570550088749025, "gcm.notification.meta": {"property_id":46}, "body": A new property has just been listed in your area by Ebenezer Kilani, "aps": {
alert = {
body = "A new property has just been listed in your area by Ebenezer Kilani";
title = "New property Listing";
};
}, "google.c.a.e": 1, "gcm.notification.type": new_property]
the second payload just opens the application but never goes into the view controller I need it to. That is, it opens the home page only.
How I am getting the userInfo
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
if let usrInfo = userInfo as? [String: Any] {
extractUserInfo(userInfo: usrInfo, completion: completionHandler)
}
completionHandler()
}
func extractUserInfo(userInfo: [String: Any], completion: #escaping () -> Void) {
if let type = userInfo["gcm.notification.type"] as? String {
Storage.instance.savePush(type)
if type == "new_property" {
if let meta = userInfo["gcm.notification.meta"] as? String {
if let data = meta.data(using: .utf8) {
do {
if let json = try JSONSerialization.jsonObject(with: data, options: .allowFragments) as? [String: Any] {
guard let propertyId = json["property_id"] as? String, let id = Int(propertyId) else {return}
NotificationEvent.isFromNotification.accept(true)
NotificationEvent.id.accept(id)
} else {
print("JSON is invalid")
}
} catch {
print("Exception converting: \(error)")
}
}
}
}
}
}
how I handle the push to display required Viewcontroller
class Remote {
var navigationController: UINavigationController?
let disposeBag = DisposeBag()
#discardableResult
init(navigationController: UINavigationController?) {
self.navigationController = navigationController
rxEvent()
}
func rxEvent() {
NotificationEvent.isFromNotification.asObservable().subscribe(onNext: { bool in
print("Exception converting: bool \(bool)")
if bool {
NotificationEvent.id.asObservable()
.delay(1, scheduler: MainScheduler.instance)
.subscribe(onNext: { int in
if int > 0 {
if Storage.instance.getPush() == "new_property" {
self.presentPropertyDetailVC(int)
} else if Storage.instance.getPush() == "new_rating" || Storage.instance.getPush() == "coverage_area" {
print(int)
}
}
}).disposed(by: self.disposeBag)
NotificationEvent.isFromNotification.accept(false)
}
}).disposed(by: disposeBag)
}
func presentPropertyDetailVC(_ uid: Int) {
// navigationVC.modalPresentationStyle = .formSheet
let controller = PropertyDetailVC()
controller.propertyId = uid
print("Exception converting: 11 \(controller)")
navigationController?.pushViewController(controller, animated: true)
}
}
then I instantiate Remote in my home VC
Any reason why the first payload work and the second does not and anything I could do to correct that.

This line
guard let propertyId = json["property_id"] as? String, let id = Int(propertyId) else {return}
is getting to the "return" because on the second meta 46 is an int not a string (note that it have not quotes. To fix it you can try
guard let propertyId = json["property_id"] as? String ?? String(json["property_id"] as? Int ?? 0), let id = Int(propertyId) else {return}
