Adding Service Extension

Notification Service Extension is used to display media notifications like Image, Video, Audio, and Gif sent from CEE .

  1. In your Xcode go to menu File > New > Target > Select Notification Service Extension.
  2. Click the Next button and fill in the Product Name. Throughout this document, we are using SmartechNSE as the example Product Name.
  3. Click the Finish button.
  4. Set the deployment target to 10.0 or above.
  5. You need to create a different Bundle Identifier and provisioning profile for this extension. For example ‘com.CompanyName.ProductName.ProductNameServiceExtension’

Adding Content Extension

Notification Content Extension is used only to display carousel notifications sent from CEE .

  1. In your Xcode go to menu File > New > Target > Select Notification Content Extension.
  2. Click the Next button and fill in the Product Name, here in the example we are using SmartechNCE.
  3. Click the Finish button
  4. Set the deployment target to 10.0 or above.
  5. You need to create a different Bundle Identifier and provision profile for this extension. For example ‘com.CompanyName.ProductName.ProductNameContentExtension’

Enabling Capabilities for Service and Content Extension

📘

Note:

  1. Make sure you add App Transport Security Settings with Allow Arbitrary Loads as YES in Info.plist of App, Service Extension and Content Extension to support Http calls.
  2. App Groups must be same between App, Service Extension, and Content Extension.

For CEE SDK to work in your project you need to enable below app capabilities in your main app.

  1. App Groups - Enable/Add and select a valid App Group for your app. This is used by App, Service Extension and Content Extension to access data as all three are different targets

You can refer to the below PDF for detailed steps to enable app capabilities in your main app and extensions, refer here

Configuring Service Extensions Info.plist

You need to add a key named SmartechKeys with type Dictionary. In it add the following keys and values with its types.

KeyData typeDescription
SmartechAppGroupStringThe app group that is selected in capabilities section. It is used to share data between App and Extensions.
SmartechAppIdStringThe app id received from Smartech panel under assets section.

Following is the source code snippet of service extensions Info.plist for key SmartechKeys:

<key>SmartechKeys</key>
    <dict>
        <key>SmartechAppGroup</key>
        <string>group.com.CompanyName.ProductName</string>
        <key>SmartechAppId</key>
        <string>abcdef123456abcdef123456abcd1234</string>
    </dict>

Configuring Content Extensions Info.plist

You need to add a key named SmartechKeys with type Dictionary. In it add the following key and value with its type.

KeyData typeDescription
SmartechAppGroupStringThe app group that is selected in capabilities section. It is used to share data between App and Extensions.

Following is the source code snippet of content extensions Info.plist for key SmartechKeys:

<key>SmartechKeys</key>
	<dict>
		<key>SmartechAppGroup</key>
		<string>group.com.CompanyName.ProductName</string>
	</dict>

Changes in Podfile

If you are using the framework from cocoapods then you need to update it with the following lines in Podfile.

#service extension target
target 'YourServiceExtensionTarget' do
  ###
  
  # Pods for 'YourServiceExtensionTarget'
  pod 'Smartech-iOS-SDK', '~> 3.1.4'
  
  
end
 
#content extension target
target 'YourContentExtensionTarget' do
  ####
  
 
  # Pods for 'YourContentExtensionTarget'
  pod 'Smartech-iOS-SDK', '~> 3.1.4'
  
  
end

Below is the final output of your Podfile.

# Uncomment the next line to define a global platform for your project
platform :ios, '10.0'
 
#app target
target 'YourAppTarget' do
  ###
  
  
  # Pods for YourAppTarget
  pod 'Smartech-iOS-SDK', '~> 3.1.4'
  
end

#service extension target
target 'YourServiceExtensionTarget' do
  ###
  
  # Pods for 'YourServiceExtensionTarget' 
  pod 'Smartech-iOS-SDK', '~> 3.1.4'
  
end
 
#content extension target
target 'YourContentExtensionTarget' do
  ###
  
  # Pods for 'YourContentExtensionTarget'
  pod 'Smartech-iOS-SDK', '~> 3.1.4'
  
end

These updated lines in your Podfile will install the Smartech SDK for both the extensions. Save this file and install the dependencies which are added for extensions with pod install command via terminal.

pod install

Configuring Service Extension with CEE SDK

You need to perform the following changes in the Notification Service Extension's NotificationService class.

Create an object of SMTNotificationServiceExtension and call the methods

//In NotificationService.h

#import <UserNotifications/UserNotifications.h>

@interface NotificationService : UNNotificationServiceExtension

@end

 
//In NotificationService.m

#import "NotificationService.h"
#import <Smartech/Smartech.h>

@implementation NotificationService

SMTNotificationServiceExtension *smartechServiceExtension;

- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
  //...
  if ([[Smartech sharedInstance] isNotificationFromSmartech:request.content.userInfo]) {
     smartechServiceExtension = [[SMTNotificationServiceExtension alloc] init];
     [smartechServiceExtension didReceiveNotificationRequest:request withContentHandler:contentHandler];
 }
  //...
}

- (void)serviceExtensionTimeWillExpire {
  //...
  [smartechServiceExtension serviceExtensionTimeWillExpire];
  //...
}

@end

import UserNotifications
import Smartech

class NotificationService: UNNotificationServiceExtension {
  
  let smartechServiceExtension = SMTNotificationServiceExtension()
  
  override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
    //...
	if Smartech.sharedInstance().isNotification(fromSmartech:request.content.userInfo) {
	 smartechServiceExtension.didReceive(request, withContentHandler: contentHandler)
 }
    //...
  }
  
  override func serviceExtensionTimeWillExpire() {
    //...
    smartechServiceExtension.serviceExtensionTimeWillExpire()
    //...
  }
}

Configuring Content Extension with CEE SDK

Replace the following code in your NotificationViewController class

//This is NotificationViewController.m file

#import "NotificationViewController.h"
#import <UserNotifications/UserNotifications.h>
#import <UserNotificationsUI/UserNotificationsUI.h>
#import <Smartech/Smartech.h>

@interface NotificationViewController () <UNNotificationContentExtension>

@property (weak, nonatomic) IBOutlet UIView *customView;

@end

@implementation NotificationViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    [[Smartech sharedInstance] loadCustomNotificationContentView:self.customView];
}

- (void)didReceiveNotification:(UNNotification *)notification {
    [[Smartech sharedInstance] didReceiveCustomNotification:notification];
}

- (void)didReceiveNotificationResponse:(UNNotificationResponse *)response completionHandler:(void (^)(UNNotificationContentExtensionResponseOption option))completion {
    
    [[Smartech sharedInstance] didReceiveCustomNotificationResponse:response completionHandler:^(UNNotificationContentExtensionResponseOption option) {
        completion(option);
    }];
    
}

@end

import UIKit
import UserNotifications
import UserNotificationsUI
import Smartech

class NotificationViewController: UIViewController, UNNotificationContentExtension {
    
    @IBOutlet var customBgView: UIView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        Smartech.sharedInstance().loadCustomNotificationContentView(customBgView)
        // Do any required interface initialization here.
    }
    
    func didReceive(_ notification: UNNotification) {
        Smartech.sharedInstance().didReceiveCustomNotification(notification)
    }
    
    func didReceive(_ response: UNNotificationResponse, completionHandler completion: @escaping (UNNotificationContentExtensionResponseOption) -> Void) {
        Smartech.sharedInstance().didReceiveCustomNotificationResponse(response) { (option) in
            completion(option)
        }
    }
}

For storyboard changes in your Content Extension, you need to check this PDF.

In your Content Extensions Info.plist under NSExtension -> NSExtensionAttributes

  1. Change the UNNotificationExtensionCategory datatype with Array in which it will be consisted of 3 values :
    a. Item 0 will be of type String with value SmartechCarouselLandscapeNotification
    b. Item 1 will be of type String with value SmartechCarouselPortraitNotification
    c. Item 2 will be of type String with value SmartechCarouselFallbackNotification.
  2. Add the UNNotificationExtensionDefaultContentHidden key with Boolean value NO.
