Getting Started with iOS

Getting Started with iOS


Apache Cordova is a library used to create native mobile applications using Web technologies. The application is created using HTML, CSS and JavaScript and compiled for each specific platform using the platform native tools. Cordova provides a standard set of JavaScript APIs to access device features on all supported platforms. This document describes how to get started using Apache Cordova for the iOS platform.


Install Cordova

Download Cordova

Download the latest version of Apache Cordova from Click on the Download icon and select to download to your machine. The X, Y and Z represent the version number of Cordova, for example 2.5.0. The download includes the code for all of the Apache Cordova supported platforms. 

Extract Cordova

To access the code it will need to be extracted from the archive (.zip) file.

  1. Navigate to the folder where you downloaded the code. Find the file. 
 Note: The file names change with each new version of Cordova. The file name will be different if you are using an updated or newer version of Cordova.

  2. Using the Finder® app, double click the file to extract. This will create a directory named, cordova-X.Y.Z. 

  3. Expand this folder and locate the file and double click to extract it. 

  4. The code for iOS is within the cordova-ios directory structure.

Project Creation

Xcode projects for Cordova are created by invoking a script file via the command line. The following steps explain how to create the necessary directory structure, open and use the Terminal application to create a new project, and execute the create script. 

Determine Project Location

Determine where on your system you will locate the Xcode project files for your application. For this tutorial I created a CordovaXY directory under my Documents folder: ~/Documents/CordovaXY where the X and Y refer the to Cordova version #.

  1. In Finder navigate to the Documents Directory. 

  2. Create a directory called CordovaXY within the Documents directory where the X and Y represent the Cordova version number (23, for example). You can use a different directory name or location if you wish but you will need to remember this directory location and name for subsequent steps.

Open Terminal

  1. In Finder, navigate to the Applications Folder. Find and expand the Utilities Folder.

  2. Locate the Terminal app and double click to open it. 

  3. In Finder, navigate to the cordova-ios directory from the downloaded and extracted Cordova code and expand it if necessary. Highlight the bin directory as shown:

    Note: This screen capture was from the Cordova-2.3.0 download, your listing will vary based on the actual Cordova version installed.

  4. Drag this directory to the open Terminal icon in the dock. This will open up a default terminal window with the path set to the bin directory.

Create New Project

Command Line Syntax

  1. Determine Required Parameters

    There are 3 ordered, required parameters for creating a Cordova project from the command line:

    1. project location

      This is the directory where the Xcode project and files for the application will be located. This tutorial is using ~/Documents/CordovaXY as the base location and the application name as the project directory. Thus the location for our project will be 
~/Documents/CordovaXY/HelloWorld, where HelloWorld is the project name (note that the X and Y represent the Cordova version, for example 22 for version 2.2). The final directory, HelloWorld in this example, must not already exist as it will be created during execution of the command.

    2. package name

      When submitting apps to the App Store, this must be the reverse domain name App ID that is created via the Apple Provisioning Portal (described in the Deploy to Device section). The Provisioning Portal is accessible once you have paid for and signed into your iOS Developer Account. Since you will not be submitting this sample app, this tutorial uses org.apache.Cordova plus the app name, HelloWorld: 

    3. project name

      This is the name of the actual project. Most developers make the project name and the application name the same. In this example the project name is HelloWorld.

  2. Execute the Command

    In the terminal app with bin as the current directory, enter the 3 pieces of information via the following command: 
./create ~/Documents/CordovaXY/HelloWorld org.apache.cordova.HelloWorld HelloWorld

  3. Fix Common Problems

    No Developer Directory Found

    The “Error: No developer directory found at /Developer” message is displayed if the create script can not find the location of the command line tools within Xcode. This can occur if more than one version of Xcode is installed on the system or when upgrading from older versions of Xcode. The solution is to run the xcode-select command to set the location. If you have installed Xcode in the default location the command to execute is:

       sudo /usr/bin/xcode-select -switch /Applications/


    See for more information on the xcode-select command if you have installed Xcode in a different location.

Optional Features

Running the Application

Open the Project

Using the Finder app, navigate to the location where you created the project. This guide uses ~/Documents/CordovaXY/HelloWorld. Double click the HelloWorld.xcodeproj file to open the project in Xcode.

Your screen should look similar to:

Note: this screen capture shows a project that was created with the name as HelloWorld23. 

Deploy to the Simulator

  1. In the upper left hand corner of Xcode, click on the Scheme drop down and select the project name, HelloWorld, as the target. 

  2. Click the device section and select an iOS Simulator such as iPhone 6.0 Simulator as shown: 

  3. Click the Run button in your project window's toolbar to build, deploy and run the application in the simulator. 

Deploy to the Device


There are several requirements to deploy to a device. Since this information is not related directly to Cordova, please refer to the Apple Configuring Development and Distribution Assets section of the Tools Workflow Guide for iOS documentation for complete details.

Deployment Steps

  1. Plug your device into your Mac via the USB Cable.

  2. Select the Target and device

    1. In the upper left hand corner of Xcode, click the Scheme drop down and select the project name, HelloWorld, as the target.

    2. Click the device section and select your device from the list. If your device is plugged in via the USB but not visible in the device list, click the Organizer button to determine any errors.

  3. Click the run button to build, deploy and run the application on your device.


The running HelloWorld app is shown below. The Device is Ready line should be slowly pulsating.

Common Problems

Deprecation Warnings

When an application programming interface (API) has been changed or replaced by another API, it is marked as “deprecated.” The API will still work in the near term but will be removed in a future version of the code library. Apache Cordova contains some of these deprecated interfaces. When you build and deploy an application, Xcode will issue warnings about these deprecated APIs. The ‘invokeString’ method that Xcode is warning about represents functionality to invoke the app from a custom URL. The process for loading from a custom URL has changed but this code is included to provide backwards functionality for apps created with older versions of Cordova. The sample app does not use this functionality so the references to the items causing the warnings can be ignored.

If you wish to remove the warnings you can remove the code that is referencing the invokeString deprecated API. 

  1. Navigate to the MainViewController.m file in the Classes folder.

  2. Find and comment out the following code by surrounding it with the begin, /, and end, /, comment characters as highlighted in the code snippet below.

    (void)webViewDidFinishLoad:(UIWebView)theWebView { // only valid if _PROJECTNAME-Info.plist specifies a protocol to handle / if (self.invokeString) {

     // this is passed before the deviceready event is fired, so you can access it in js when you receive deviceready
     NSLog(@"DEPRECATED: window.invokeString - use the window.handleOpenURL(url) function instead, which is always called when the app is launched through a custom scheme url.");
     NSString* jsString = [NSString stringWithFormat:@"var invokeString = \"%@\";", self.invokeString];
     [theWebView stringByEvaluatingJavaScriptFromString:jsString];

    } */ // Black base color for background matches the native apps theWebView.backgroundColor = [UIColor blackColor];

    return [super webViewDidFinishLoad:theWebView]; }

  3. Press Command s to save the file. 

  4. Navigate to the AppViewDelegate.m file in the Classes Folder.

  5. Comment out the following line by placing a double slash at the beginning of line 73 as shown below:

    //self.viewController.invokeString = invokeString;

  6. Press Command-s to save the file.

  7. Press Command-b to rebuild the project and eliminate the warnings.

Missing Headers

Some users have encountered compilation errors relating to missing headers. This refers to a problem in the build location and is fixed via Xcode preferences. 

  1. Within the Xcode menus select Xcode>Preferences>Locations. 

  2. In the Derived Data section click the Advanced button and select Unique as the Build Location as shown: 

    This is the default setting for a new Xcode install but it may have been set differently if you upgraded from an older version of Xcode.

Next Steps

Building Your Own Applications

Include Cordova

All of the code for the sample application is contained within the www directory in the Xcode project structure. The starting page is named index.html. Any page that uses Cordova must include the cordova-*.js file for the associated Cordova version and platform. The format of the JavaScript file name is cordova-x.y.z where x represents the major version number, y the minor version and z any point release. For example, the Cordova 2.2.0 file was named cordova-2.2.0.js. The sample HelloWorld application includes this file from index.html.

  <script type="text/javascript" src="cordova-2.2.0.js"></script>
  <script type="text/javascript" src="js/index.js"></script>
  <script type="text/javascript">

Wait for deviceReady Event

When loading a page, Cordova’s deviceReady event must fire before you can access any of the platform features via the Cordova JavaScript APIs. Within the sample application this is set up within the app object found within the js/index.js file. The app.initialze() call at the bottom of the index.html file (visible in the previous code example) sets in motion the binding of events to receive and respond to the deviceReady event.

Another common method of initializing a page is to add an event listener for the deviceReady event within the handler for the body onload event as shown in the code snippet below:

    <script type="text/javascript" src="cordova-2.5.0.js"></script>
      function onLoad() {
      ‘deviceready’, onDeviceReady, false);
    function onDeviceReady() {
      // do Something!
      // example: display a Cordova Alert
      // see for full details
        'Cordova is ready!',          // message
        function() {//do something},  // callback
        'Congratulations',            // title
        'Done'                       // buttonName
    <body onload=”onLoad();”>

Code Your Application

Replace the sample code in the www directory of a new project with the HTML, JavaScript and CSS code for your application. The name of the initial file to load when the app is launched should be index.html (advanced users can change this if necessary). As demonstrated in the HelloWorld sample application, subdirectories within the www directory are permitted. Note that the www directory is readonly, you can not write information to this directory during app execution. If you need to store information use the Cordova File or Storage APIs.

You can use many mobile JavaScript frameworks with Cordova to create the UI and page navigation of your application. Popular ones include:

Modify Project Settings

There are many additional considerations to make your application unique. The sample HelloWorld application is set up to run in all iOS environments, iPhone, iPod, and iPad. You can design an app for a single device type by modifying the build settings within Xcode.

You should customize the application with your own icons and splash screens. The sample application includes Cordova specific images in the Apple required sizes and resolutions as examples. The Cordova Specific settings are located in the config.xml file and documented in the Cordova Project Settings Guide. Refer to the Resources section for more Apple specific information about building iOS Apps.
