![]() ![]() Let’s first look into some of our class’ variables: Now that you got the gist of it, let’s get into the coding! Setting The View Controller’s Variables This broadcasting of the location has been described in a previous blog entry we encourage you to read! In this article, we will describe the process of getting this information via PubNub and drawing your friend’s commute on a map. In our app, we will be listening to a friend who will be sending us frequent information on his current position. Use PubNub to Know Where Your Friends Are in Real time It’ll be something like “YourProject/YourProject-Bridging-Header.h”Īt this point, we should be all set! We can finally start coding! Let’s roll. Set the “install Objective-C Bridging Header” to Yes and in “Objective-C Bridging Header” type the path from your project’s root directory to your bridging header. Now in your project’s configuration panel, go to build settings and scroll down to the “Swift Compiler – Code Generation” section. Create a new Objective-C header in your project called YourProject-Bridging-Header.h for good practice, and type: All you need to do now is to build a bridging header. The PubNub library is written in Objective-C, but we are coding in Swift. That wasn’t too hard right? It’s not quite over though. You can make sure you are using the latest version of PubNub here.Ĭlose Xcode, and open the YourProject.xcworkspace. Easy installation and starter’s guide here! ![]() If you don’t use it yet, you’re missing out. Let’s start by setting up our project properly! We will want to use the PubNub SDK for iOS. ![]() We’ve included a migration guide to help you move from 3.x to 4.0, and a getting started guide to help you create a simple Hello World application in minutes. The code from this tutorial still works great, but we recommend checking out our new SDK. We rebuilt the entire codebase and took advantage of new features from Apple, simplifying and streamlining the SDK. ** NOTE: Since we wrote this tutorial, we’ve released a new, completely-redesigned version of our iOS SDK (4.0). If you haven’t already, check out our first tutorial on how to retrieve and broadcast location coordinates with iOS. And if you’d rather use a different mapping SDK, we’ve got you covered! Check out our same tutorial using the GoogleMaps API or MapKit API. Using the Mapbox API to draw locations on a map in real timeĬlick to download the full source code for the entire project here.Using PubNub to listen to a channel with Swift.The app will retrieve and broadcast location data, then your subscriber receives the location data and streams changes to create a smooth and consistent iOS location tracking app. In this tutorial, we’re going to use the Mapbox API to receive and publish iOS location data on a live-updating map. ![]()
