Discover geocoding and reverse geocoding to convert addresses to coordinates and vice versa, locate users with GPS, and render maps with iOS maps and MapKit, including directions.

Learn geocoding and reverse geocoding in iOS using CLGeocoder to convert addresses to latitude and longitude and back, handle multiple results, and format international addresses.

Display a map in iOS apps using Core Location, geocoder, and MapKit to convert an address to coordinates, center a map region, and drop a place mark.

Learn to display a map, geocode addresses into place marks, and render driving directions using MKMapItem and MKLaunchOptions. Switch between walking or mass transit and remember maps require internet access.

The lecture demonstrates using the location manager to obtain the current user location, requesting when-in-use authorization, and handling updates to latitude, longitude, altitude, and accuracy through a delegate.

Learn to build an iOS app that calculates the distance from your current location to a target address using location manager and geocoder, converting meters to miles.

Build a simple map app using map kit by geocoding a user-entered address, centering the map on the result, and setting a radius with MKCoordinateRegion.

Choose road or satellite map types and zoom around a geocoded address using a slider, centering the map view and updating with user input.

Display the user's current GPS location on the map, request when-in-use authorization, center the map, provide road or satellite view, adjust zoom, and reverse geocode to show the address.

Explore the motion framework to access the accelerometer, gyroscope, and compass, determine device orientation, direction, and pace, and use gestures or game-style controls in iOS apps.

Explore the iOS motion framework by measuring acceleration and rotation with the accelerometer and gyroscope, using polling and event-driven updates via a motion manager.

Control a blue dot with the accelerometer using Core Motion, turning tilt into game motion and guiding the dot through a maze.

Learn to read gyroscope data in x, y, and z axes with a Core Motion motion manager, set a 0.1 second update interval, and track maximum rotations via event-driven updates.

Learn to build a compass using the magnetometer via Core Location's location manager, calibrate, and rotate an arrow image to point north with heading updates.

Learn how to add social networking to iOS apps by posting to Facebook and Twitter via simple APIs or your own UI, and compare built-in versus custom approaches.

Explore iOS social networking options, from UIActivityViewController to SLComposeViewController, SLRequest, and full SDKs, comparing simplicity and UI control with Facebook and Twitter Open Graph sharing.

Explore how to implement a basic iOS sharing flow with the UIActivityViewController, handling text and optional image with an image picker, and previewing posts for Twitter or Facebook.

Use the SLComposeViewController to post to a specific service like Facebook or Twitter from your app, with an image and preset text.

Post to Twitter directly with SLRequest by selecting a Twitter account and sending a status update. Configure the user interface, request access, and handle responses within the app.

Learn to read the Twitter timeline by requesting Twitter accounts, using SLRequest to fetch 25 posts with include_entities, and display results in a table view.

Post to Facebook using SLRequest by configuring a Facebook app ID, developer account, and bundle ID, requesting read then publish permissions, and sending the message through the Accounts framework.

Create a new iOS app on the Facebook developer portal, install the Facebook SDK, and add Info.plist keys, app transport security, and LSApplicationQueriesSchemes to enable the like button.

Set up the Facebook SDK for an iOS app, use the login button with read and publish permissions, and post a hello world message to the user's wall.

Learn to read a Facebook user profile with the Facebook SDK using a login button, an access token, and a graph request to /me for id, name, and picture.

Learn how CloudKit offers cloud storage with a lightweight remote database, storing objects like customers and orders, with private or public access and simple setup.

Set up iCloud and CloudKit for your app by configuring the bundle identifier, enabling iCloud with CloudKit, creating containers and entitlements, and using the CloudKit dashboard for record types.

Learn how to fetch CloudKit records from the public database and display them in a table view, using a customer object mapped to CloudKit fields.

add a customer record to the CloudKit public database by creating a CKRecord of type customer, setting name, address, city, state, and saving to the default zone.

Explore in-app purchasing options, including disposable content, feature unlocks, and subscriptions, and compare them with eye ads as a simple monetization approach, covering setup and receipt validation.

Explore in-app purchases for iOS apps, including consumables, non-consumables, and subscriptions, with cross-device transfers, downloads, and the purchase flow using SKProduct, SKPaymentQueue, and receipt validation.

Explore how to validate App Store receipts to prevent hacks, comparing in-app validation and server validation, and understand the role of device info, transaction IDs, and purchase dates.

Post the receipt to your server for validation with Apple's service, then verify status, product id, bundle id, and purchase date for sandbox or live mode.

Set up your iOS app with Apple by creating certificates, identifiers, and provisioning profiles, then sign the app in Xcode and configure iTunes Connect for in-app purchases, agreements, and readiness.

Test in-app purchases with the sandbox, using the same validation process but the Apple sandbox URL. Create sandbox testers in iTunes Connect, and use TestFlight users for beta distribution.

Create and configure in-app purchases by selecting type (consumable or non-consumable), setting a unique product ID, choosing pricing tiers, adding localization, and specifying hosting content with Apple and review notes.
