Looks like it it is working, but it is very slow and sometimes does not retrieve all the images. Now remove all the functions of the file except viewDidLoad so that we have clarity in the file.I am trying to set up a feed page with a UITableView, retrieving all the JSON data from Node.js API. Once we do this, we can then add and test all the possible manipulations we want the table to have such as moving rows around, deleting rows and adding new rows to the table. The first thing we want to do is populate our table with some mock data. Populating our iOS table with user data and manipulating it Great! Now we are done with the user interface of the application, let us start creating the logic that will populate and make our iOS table realtime. Next, create a new TableViewController and attach to it to the root view controller using the storyboard’s identity inspector as seen below: We have named our reuse identifier user but you can call the reuse identifier whatever you want. Click on the prototype cell and add a new reuse identifier. Now we need to add a reuse identifier to our table cells. You should now have something like this in your storyboard:Īs seen in the screenshot, we have a simple navigation controller and we have made the table view controller attached to it our Root View Controller. Also, dont store your array in UserDefaults, its for. Suppose you load the data from persistent storage. Drag and drop a Navigation Controller to the storyboard and set the entry point to the new Navigation Controller. The general idea would be on add button tap (or whatever event listener you want to attach the action to), save it to persistent storage, reload your tableView, since the dataSource is from persistent storage, itll update automatically. Once Xcode has finished loading, we can now start building our interface. Building the User Interface of our realtime table on iOS Now we are ready to start creating our iOS application. Once the installation is complete, open the **.xcworkspace** file in your project directory root. Running this command will install all the third-party packages we need to build our realtime app. Save the Podfile and then run the command: pod install on your terminal window. Update the contents of the Podfile to the contents below (replace PROJECT_NAME with your project name): platform :ios, '9.0' In the terminal window, cd to the root of the app directory and run the command pod init. Once the project has been created, close Xcode and launch the terminal. the tableview and amount of sets input are in two different viewcontrollers. The problem I am facing is that I do not know how to get the tableview data and duplicate by however many times the user wants to(the amount of sets they want to do). Follow the new application wizard and create a new Single-page application. I have already implemented a way for the user to input the amount of sets they wish to do. Preparing our environment to create our application Once you have you have all the following then let us continue in the article. – Cocoapods ****installed on your machine. – Node.js and NPM installed on your machine – Basic knowledge of JavaScript (Node.js) – Basic knowledge of Swift and using Xcode Requirements for building a realtime table on iOSįor you to follow this tutorial, you will need all of the following requirements: Let us consider how to make this using Pusher and Swift. In the recording above, you can see how the changes made to the table on the one device gets mirrored instantly to the other device. You can see a screen recording of how the application works below. In this article, you will see how you can use iOS and Pusher to create a table that is updated across all your devices in realtime. Now, imagine the data that populated the table was to be reordered or altered, it would be nice if everyone viewing the data on the table sees the changes made instantaneously. Think of a list of users for example, or a table filled with data about the soccer league. More often than not, when you build applications to be consumed by others, you will need to represent the data in some sort of table or list. Class UserDefaults An interface to the user’s defaults database, where you store key-value pairs persistently across launches of your app.
