Setting up push notifications for your iOS app is easy. Push notifications are the ideal solution to re-engage users and bring them back to your app. This guide tells you how to configure an iOS app to send and receive push notifications on any Apple mobile device, whether it's an iphone, an ipad, or an Apple watch.

Estimated setup time: 15 minutes.

Prerequisites

Getting started with WonderPush is easy.

You'll need:

• Xcode
• An iOS device such as an iPhone or an iPad
• An iOS Push Certificate (here's a how to obtain it)
• An Xcode project your iOS application

Step 1. Create your project

Click on New Project:

Choose a name for your project and select iOS as a platform then click Create:

Step 2. Upload your push certificate

Go to Settings / Platforms, click the iOS application section title and fill in:

• your push certificate by clicking the Browse button,
• the push certificate password if appropriate.

Step 3. Create the notification service extension

In Xcode, select File / New / Target..., and choose Notification Service Extension:

Enter WonderPushNotificationServiceExtension as the name for your new target:

When Xcode prompts you to activate the new scheme, answer Cancel to keep Xcode building and debugging your app instead of the extension:

If you activate by mistake, switch back to your app's scheme from the dropdown menu located next to the play button.

Set the Deployment Target of your Notification Service Extension to 10.0:

Step 4. Integrate WonderPush to your Xcode project

Setup CocoaPods on your system if you haven't already.

If you do not wish to use CocoaPods, you can follow our Manual Integration Guide.

If your project doesn't have a Podfile, run the following command from the same directory that contains your .xcodeproj:

pod init

Add WonderPush to your Podfile:

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'MyApp' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for MyApp
  pod 'WonderPush', '~> 3.0'
end

target 'WonderPushNotificationServiceExtension' do
  platform :ios, '10.0'
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for WonderPushNotificationServiceExtension
  pod 'WonderPushExtension', '~> 3.0'
end

Finally, run:

pod install

Open the newly created <my-app>.xcworkspace file.

Step 5. Add device capabilities

Select your app's main target and, under the Capabilities tab, make sure:

• the Background Modes capability is ON,
• the Remote notifications background mode is checked,
• the Push Notifications capability is ON.

Step 6. Add required code

Take note of your Client ID and Client Secret from the iOS app tab of the Settings / Configuration page:

Open your AppDelegate and add the following, adapting YOUR_CLIENT_ID and YOUR_CLIENT_SECRET with the values you've noted above:

import WonderPush

func application(_ application: UIApplication, willFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        WonderPush.setClientId("YOUR_CLIENT_ID", secret: "YOUR_CLIENT_SECRET")
        WonderPush.setupDelegate(for: application)
        WonderPush.setupDelegateForUserNotificationCenter()
        return true
}

#import <WonderPush/WonderPush.h>
  
- (BOOL)application:(UIApplication *)application willFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [WonderPush setClientId:@"YOUR_CLIENT_ID" secret:@"YOUR_CLIENT_SECRET"];
    [WonderPush setupDelegateForApplication:application];
    [WonderPush setupDelegateForUserNotificationCenter];
    return YES;
}

Let's add the code that will prompt users to subscribe to push notifications. We recommend you place this code in a more suitable place in the user journey, but we'll do it at launch time for now. In your AppDelegate:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    // Prompts users to subscribe to push notifications.
    // Move this in a more suitable place in the user journey.
    WonderPush.subscribeToNotifications()
    return true
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    // Prompts users to subscribe to push notifications.
    // Move this in a more suitable place in the user journey.
    [WonderPush subscribeToNotifications];
    return YES;
}

Finally, we'll modify the code of the Notification Service Extension you created in Step 3. Replace the whole contents of NotificationService.swift or (NotificationService.h and NotificationService.m for Objective-C) with :

import WonderPushExtension

class NotificationService: WPNotificationServiceExtension {
}

#import <WonderPushExtension/WonderPushExtension.h>

@interface NotificationService : WPNotificationServiceExtension

@end

#import "NotificationService.h"

@implementation NotificationService

@end

Receive your first push!

Let take your iphone or your ipad, and discover your first iOS Push notification.

Build & run your application and get the permission prompt you've configured:

Wait a couple of minutes and receive the default welcome notification:
