iPhone: Push Notifications & Social Media (Swift 5 & iOS 13)

Learn how to enable and integrate push notifications in your apps using procedural steps, with the Instagram clone from a prior section guiding the workflow.

Learn to enable push notifications for an iOS app using OneSignal, test on iPhone with a developer account, and configure APNs certificates via CSR, Keychain Access, and a P12 file.

Learn to integrate the one signal push notification SDK into an iOS 13 Swift 5 project, including configuring p12, app id, and a notification service extension.

Demonstrates sending a manual push notification using one signal, testing on a real iPhone, subscribing users, and sending dashboard messages while debugging permissions and pod updates.

Learn to send push notifications from Xcode using one signal, targeting a single user with a player ID and composing the content.

Learn how to obtain the player ID via OneSignal, save it to Firebase Firestore with the current user's email, and retrieve it for targeted push notifications.

Learn how to prevent duplicate player IDs by querying Firestore for the current user, handling empty results, and conditionally saving or updating the player ID for push notifications.

Add push notifications to an iPhone app by integrating like functionality with OneSignal and Firestore, sending personalized alerts when a user likes a post, and test on devices.

Discover how Parse powers a simple Instagram clone by storing usernames, passwords, and images on a server and integrating into an iOS project.

Integrate parse into your iPhone project with CocoaPods, install the pod, and open the generated Xcode workspace to build a tabbed app with two view controllers and a navigation controller.

Design and implement a functional iOS user interface with a tab bar, feed and upload views, and a sign-in sign-up flow using text fields and action buttons.

Configure Parse in the app delegate by initializing the Parse client with the application ID, client key, and server, then set PFACL for current user and public ACL.

Launch an AWS server by navigating the AWS console, signing up, and selecting a free tier instance; create a key pair, launch the instance, and monitor status checks until running.

Connect to the server by selecting a client option, then use ssh or manual key setup, copy the application id and server details, and log in to the dashboard.

Store data to parse by creating a PFObject (fruits), setting fields like name and calories, saving in the background, and validating results in the dashboard.

Retrieve objects from Parse by querying the fruits class for name equals Mallam and calories greater than one, filter results, print outputs, and handle errors.

Implement a user sign-up flow by validating username and password, presenting alerts on errors, and creating a user object with username and password, handling success or account already exists cases.

Sign in users by validating the username and password, checking user existence, handling errors, and performing a segue to the main interface with login progress.

Remember the signed-in user by storing the username in user defaults, check on app launch, and skip sign-in by directing to the tab bar feed when a username exists.

Add a logout function with a navigation bar item, perform logout in background, handle errors, clear stored username, and return to sign-in screen.

Create an upload view controller that lets users pick an image, enter a comment, and post it using an image picker and gesture recognizers for keyboard dismissal.

Create and upload your first post with a parse object, attach a compressed image, add comments and user data, and refresh the feed to view it.

Create a feed view using a table view and prototype cell to display posts with image and username. Wire the table view to its delegate and data source.

Retrieve post data from Parse and populate the feed with user names, comments, IDs, and images, then update the table view to show posts chronologically.

Implement safeguards for post submissions by toggling the post button, handling image selection, and preventing duplicate posts, while using notification center to refresh the feed and keep data in sync.

This lecture shows implementing likes and comments in a social feed by creating like objects with sender and post IDs, saving actions in background, and handling errors with alerts.

Enable push notifications in the Instagram clone app by configuring target capabilities and background modes, after signing up for an Apple developer account.

Configure OneSignal for iOS push notifications by creating an app, generating and exporting a P12 certificate via keychain and Apple developer, then uploading it to OneSignal.

Register OneSignal in your iOS app by adding the notification service extension and app ID, then initialize it in the app delegate and test on a real device.

Explore sending manual push notifications from the dashboard, including segmenting users, composing the message, badges, and scheduling, with a plan to automate the process in the next lecture.

Learn how to implement automated push notifications in Xcode using OneSignal, including composing content, targeting by include player IDs, testing with multiple simulator users, and integrating in the feed controller.

Map user IDs to player IDs and push tokens using OneSignal and Parse, storing mappings in a player IDs object to enable targeted push notifications.

Learn to trigger push notifications when a user likes a post by querying post owner with parse, then send a OneSignal alert that the current user has liked your post.

Learn how to configure push notifications and comment updates in an iPhone app by using a limit to deliver a single notification, adjusting preferences, and testing on the simulator.

Learn to increment the app badge number using push notifications, update post notification methods, and handle batch counts as strings, then verify badge updates on the home screen.
