Section 2: Installing and Setting up DocScan

To get started with DocScan, follow these steps:

1. Open the App Store on your iOS device and search for "DocScan".
2. Download and install the app.
3. Once installed, open the app and agree to the terms and conditions.
4. Tap on the "Scan" button to start the scanning process.

Section 3: Admob Integration

To integrate Admob into your DocScan app, follow these steps:

1. Create an Admob account and create a new ad unit for your app.
2. Open the DocScan project in Xcode and add the Admob SDK by importing the Admob framework.
3. Initialize the Admob SDK in the application(_:didFinishLaunchingWithOptions:) method:

   
   import GoogleMobileAds

class AppDelegate: UIResponder, UIApplicationDelegate { func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { // Initialize Admob GADMobileAds.sharedInstance().start() return true } }

4. Add an Admob banner view to your app's main screen:
```swift
import UIKit
import GoogleMobileAds

class ViewController: UIViewController, GADBannerViewDelegate {
    var bannerView: GADBannerView!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Create and add an Admob banner view
        bannerView = GADBannerView(adSize: kGADAdSizeBanner)
        bannerView.rootViewController = self
        bannerView.delegate = self
        view.addSubview(bannerView)
        // Load the ad
        bannerView.load(GADRequest())
    }
}

1. Set up Admob ads in the didReceiveMessage method:

   func didReceiveMessage(_ request: GADRequest) {
   // Load the ad
   bannerView.load(request)
   }

   Section 4: In-app Purchase (IAP) Setup

To set up In-app Purchase (IAP) in your DocScan app, follow these steps:

1. Create an In-app Purchase (IAP) product in the App Store Connect portal.
2. Open the DocScan project in Xcode and add the StoreKit framework.
3. Import the StoreKit framework:

   import StoreKit

4. Create an SKPaymentQueue instance and add a payment observer:

   let paymentQueue = SKPaymentQueue.default()
   paymentQueue.add(self)

5. Implement the paymentQueue(_:updatedTransactions:) method:

   func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
   for transaction in transactions {
       switch transaction.transactionState {
       case.purchased:
           // Purchase successful, unlock the feature
           unlockFeature()
       case.failed:
           // Purchase failed, show an error message
           showError(message: "Failed to purchase")
       default:
           break
       }
   }
   }

   Section 5: Push Notifications Configuration

To set up Push Notifications in your DocScan app, follow these steps:

1. Create a Push Notification certificate in the App Store Connect portal.
2. Open the DocScan project in Xcode and add the Push Notifications framework.
3. Import the Push Notifications framework:

   import UserNotifications

4. Register for Push Notifications in the application(_:didFinishLaunchingWithOptions:) method:

   func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
   // Register for Push Notifications
   UNUserNotificationCenter.current().requestAuthorization(options: [.alert,.sound,.badge]) { granted, error in
       if granted {
           print("Push Notifications enabled")
       } else {
           print("Push Notifications disabled")
       }
   }
   return true
   }

5. Handle Push Notifications in the userNotificationCenter(_:didReceive:withCompletionHandler:) method:

   func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
   // Handle the Push Notification
   print("Push Notification received")
   completionHandler()
   }

   Section 6: Using DocScan

Now that you have set up Admob, In-app Purchase (IAP), and Push Notifications in your DocScan app, you can start using the app to scan documents and receipts. Here's a step-by-step guide:

1. Open the DocScan app and tap on the "Scan" button.
2. Adjust the camera settings as needed.
3. Tap on the "Scan" button to capture the document or receipt.
4. The app will automatically detect the edges of the document and apply filters to enhance the scan quality.
5. You can then save the scanned document or receipt to your device or share it with others.
