ios push notifications only work sometimes


(Austin McBride) #1

Hello,

I have an application that is essentially a park scheduling app. I have a iOS push notification setup to ask my users if they still plan on attending their booked park visit 15minutes before their visit. The problem is only 25% of the iOS push notifications actually show up on my device.

For example: If I’m going to the park at 9:00am, 12:30pm, 4:30pm, and 7:00pm I only end up getting notified for the 7:00pm visit at 6:45pm, but should get a notification for each visit.

Curiously, I have other iOS notifications setup to send me tips while I’m at the park and they almost always come through, but not the 15 minute reminder. Is there something I’m missing here?

Hi Austin

I have a question regarding message publishing. How are you scheduling push notifications to be delivered on 8:45AM, 12:15AM etc? Are messages being published from timer in Business Logic or you use delayed publishing or else? Please provide more details about the use case.

Hey Anton,

Sorry for the late reply. This is how we have setup this particular app notification. Please advise if there is something we’ve done wrong.

AppDelegate.swift:

@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void){

if response.actionIdentifier == “Notification_ok” {

let alertController = UIAlertController(title: “Confirmation”,
message: “Ok”,
preferredStyle: .alert)
let defaultAction = UIAlertAction(title: “Cancel”, style: UIAlertActionStyle.default) { (result : UIAlertAction) -> Void in
}
alertController.addAction(defaultAction)
}
else if response.actionIdentifier == “Notification_confirm”{

let application = UIApplication.shared

if application.applicationState == UIApplicationState.active{
UserDefaults.standard.set(“0”, forKey: “isFromNotification”)
NotificationCenter.default.post(name: NSNotification.Name(rawValue: “deleteBooking”), object:“0”, userInfo:response.notification.request.content.userInfo)
}else{
UserDefaults.standard.set(“0”, forKey: “isFromNotification”)
NotificationCenter.default.post(name: NSNotification.Name(rawValue: “deleteBooking”), object:“1”, userInfo:response.notification.request.content.userInfo)
}

}else
{

}
completionHandler()
}

LoggedinViewController:

func handleModifyListNotification(_ notification:Notification)
{
var dicInfo = notification.userInfo! as Dictionary
let pkName = dicInfo[“parkName”] as! String
let pkTime = dicInfo[“time”] as! String
let objId = dicInfo[“objectId”] as! String

    if notification.object as! String == "1" {
                self.deleteBooking(objId)
    }
    else
    {
        
        let alertController = UIAlertController(title: "Confirmation",
                                                message: "Are You Still going to the \(pkName) at \(pkTime)?",
            preferredStyle: .alert)
        let defaultAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.default) { (result : UIAlertAction) -> Void in
            
                self.deleteBooking(objId)
            
        }
        let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default) { (result : UIAlertAction) -> Void in
        }
        
        alertController.addAction(defaultAction)
        alertController.addAction(okAction)
        
        self.present(alertController, animated: true, completion: nil)
    
    }
}

func handleShowPopUp(_ tmpDic:NSDictionary)
{

     let APPDelegate  = UIApplication.shared.delegate as! AppDelegate
    APPDelegate.isFromNotication = false
    
    
    let  pkName = tmpDic["parkName"] as! String
    let  pkTime = tmpDic["time"] as! String
    let  objId = tmpDic["objectId"] as! String
    
    
    DispatchQueue.main.async
    {
        let alertController = UIAlertController(title: "Confirmation",
                                                message: "Are You Still going to the \(pkName) at \(pkTime)?",
            preferredStyle: .alert)
        
        
        let defaultAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.default) { (result : UIAlertAction) -> Void in
            
            self.deleteBooking(objId)
            
        }
        let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default) { (result : UIAlertAction) -> Void in
            
        }
        
        alertController.addAction(defaultAction)
        alertController.addAction(okAction)
        
        self.present(alertController, animated: true, completion: nil)
        
    }
}

Hello Austin,

What version of iOS-SDK are you using?
Also, please check this documentation which shows how to use the different scenarios of publishing push notifications via iOS SDK (e.g. repeated publishing).
