Find the Closest POIs and Display a Result Map

Location of the mobile is the first step but you may need to contextualize this location. Answering questions like “Where might be the user?”, “What could he be visiting?” is one step further to provide value to your users. In the code below a call to the Woosmap Search API is performed to find what is the closest POI from the user location. Don’t forget to load the proper POIs you want to monitor in Woosmap first (your stores/restaurants/services, yours competitors, etc). You’ll find anything about how to do this in our Woosmap Developer Documentation.

Once the location obtained and the closest store identified, plot all of this on a Static Map from Google Maps API. Thanks to the code below you’ll obtained a jpeg file to display in your notification.

Obviously, you must wait for the result of the first API call before calling the Google Maps API.

// Call API search
let task = URLSession.shared.dataTask(with: url) { (data, response, error) in
    if let error = error {
        NSLog("error: \(error)")
    } else {
        if let response = response as? HTTPURLResponse {
            NSLog("statusCode: \(response.statusCode)")
        }
        let responseJSON = try? JSONDecoder().decode(SearchAPIJson_Base.self, from: data!)
        for feature in (responseJSON?.features)! {
            //Get info POI from search API
            let body = "City = \(feature.properties!.address!.city!) \n ZipCode = \(feature.properties!.address!.zipcode!) \n Distance = \(feature.properties!.distance!)"
            
            //Set the body of the notificaiton
            self.bestAttemptContent?.body = body
            
            //Get coordinates of the POI
            latitudePOI = (feature.geometry?.coordinates![1])!
            longitudePOI = (feature.geometry?.coordinates![0])!
        }
        
        let staticMapUrl:String
        
        if latitudePOI != 0.0 {
            staticMapUrl = "http://maps.google.com/maps/api/staticmap?markers=color:red%7C\(myLatitude),\(myLongitude)&markers=color:blue%7C\(latitudePOI),\(longitudePOI)&zoom=14&size=400x400&sensor=true&key=\(self.GoogleStaticMapKey)"
        } else {
            staticMapUrl = "http://maps.google.com/maps/api/staticmap?markers=color:blue%7C\(myLatitude),\(myLongitude)&zoom=15&size=400x400&sensor=true&key=\(self.GoogleStaticMapKey)"
        }
        let mapUrl: URL = URL(string: staticMapUrl)!
        
        // Call API Google Static Map
        URLSession.shared.downloadTask(with: mapUrl) { (location, response, error) in
            if let location = location {
                // Move temporary fi@le to remove .tmp extension
                let tmpDirectory = NSTemporaryDirectory()
                let tmpFile = "file://".appending(tmpDirectory).appending(mapUrl.lastPathComponent).appending(UUID().uuidString).appending(".jpg")
                let tmpUrl = URL(string: tmpFile)!
                try! FileManager.default.moveItem(at: location, to: tmpUrl)
                
                // Add the attachment to the notification content
                if let attachment = try? UNNotificationAttachment(identifier: "", url: tmpUrl) {
                    self.bestAttemptContent?.attachments = [attachment]
                }
            }
            // Serve the notification content
            self.contentHandler!(self.bestAttemptContent!)
            }.resume()
    }
}
task.resume()

Modify the body, subtitle and attachment of the content handler to show the informations from APIs.
