Upgrading iOS

This guide shows how to modify iOS projects to upgrade from older versions of Cordova. Most of these instructions apply to projects created with an older set of command-line tools that precede the cordova CLI utility. See The Command-Line Interface for information how to update the version of the CLI.

NOTE: Xcode 5 is required. Currently, to submit to the Apple App Store, you should use the latest shipped version of the iOS SDK, which is iOS 7 and this is included only with Xcode 5.

Upgrading 3.3.0 Projects to 3.4.0

For non-CLI projects, run:

    bin/update path/to/project

For CLI projects:

Update the cordova CLI version. See The Command-Line Interface.
Run cordova platform update ios

Upgrading 3.2.0 Projects to 3.3.0

For non-CLI projects, run:

    bin/update path/to/project

For CLI projects:

Update the cordova CLI version. See The Command-Line Interface.
Run cordova platform update ios

Upgrading 3.1.0 Projects to 3.2.0

For non-CLI projects, run:

    bin/update path/to/project

For CLI projects:

Update the cordova CLI version. See The Command-Line Interface.
Run cordova platform update ios

Upgrading 3.0.0 Projects to 3.1.0

For non-CLI projects, run:

    bin/update path/to/project

For CLI projects:

Update the cordova CLI version. See The Command-Line Interface.
Run cordova platform update ios

iOS 7 Issues:

Remove width=device-width, height=device-height from the index.html file's viewport meta tag. (See the relevant bug.)
Update your media, media-capture and splashscreen core plugins for iOS 7 support.

Xcode 5 Issues:

Update your Project Settings if Xcode 5 prompts you to do so (in the Issues Navigator).
Update your Compiler for C/C++/Objective-C setting, under the Build Settings tab, Build Options section. Choose Default compiler (Apple LLVM 5.0).

Upgrade to the CLI (3.0.0) from 2.9.0

Create a new Apache Cordova 3.0.0 project using the cordova CLI, as described in The Command-Line Interface.
Add your platforms to the cordova project, for example: cordova platform add ios.
Copy the contents of the project's www directory to the www directory at the root of the cordova project you just created.
Copy or overwrite any native assets from your original project (Resources, etc.), making sure to add any new files to the .xcodeproj project. The iOS project builds inside the platforms\ios directory.
Copy the config.xml into the www directory, and remove any plugin definitions. Modify settings here instead of the platform directory.
Use the cordova CLI tool to install any plugins you need. Note that the CLI handles all core APIs as plugins, so they may need to be added. Only 3.0.0 plugins are compatible with the CLI.
Build and test.

Upgrading 2.9.0 Projects to 3.0.0

Download and extract the Cordova 3.0.0 source to a permanent directory location on your hard drive, for example to ~/Documents/Cordova-3.0.0.
Quit Xcode if it is running.
Using Terminal.app, navigate to the directory where you put the downloaded source above.
Create a new project, as described in iOS Shell Tool Guide. You need the assets from this new project.
Copy the www/cordova.js (note that it does not have a version suffix anymore, the version is in the file itself in the header) file from the new project into the www directory, and delete the www/cordova.js file.
Update the Cordova script reference in the www/index.html file (and any other files that contain the script reference) to point to the new cordova.js file.
Delete the CordovaLib directory, and copy the CordovaLib directory from the new project into your project's root directory.

NOTE: Starting with Cordova 3.0.0, plugins are not pre-installed, and you need to use the plugman command-line utility to install them yourself. See Using Plugman to Manage Plugins.

Upgrading 2.8.0 Projects to 2.9.0

Download and extract the Cordova 2.9.0 source to a permanent directory location on your hard drive, for example to ~/Documents/Cordova-2.9.0.

Update the Cordova script reference in the www/index.html file (and any other files that contain the script reference) to point to the new cordova.js file.

Update any <plugin> tags in the config.xml file to <feature> tags. Note that existing <plugin> tags still work, but are deprecated. You can copy this information in the config.xml file for a new project. For example:

 <plugins>
     <plugin name="LocalStorage" value="CDVLocalStorage" />
     <!-- other plugins -->
 </plugins>
    
 <!-- change to: (note that a <feature> tag is on the same level as <plugins> -->
 <feature name="LocalStorage">
 	    <param name="ios-package" value="CDVLocalStorage" />
 	</feature>
 	<!-- other <feature> tags -->

Note that Objective-C plugins are not whitelisted anymore. To whitelist your connections with the app whitelist, you need to set the User-Agent header of the connection to the same user-agent as the main Cordova WebView. You can get this by accessing the userAgent property off the main view-controller. The main view-controller (CDVViewController) also has a URLisAllowed method for you to check whether a URL passes the whitelist.
Device API changes:
- For iOS, device.platform used to return iPhone, iPad or iPod Touch; now it returns (correctly) iOS.
- For iOS, device.name (now deprecated for all platforms) used to return the name of the user’s device (e.g. ‘Shazron’s iPhone 5′); now it returns what device.platform used to return: iPhone, iPad or iPod Touch.
- For all platforms, there is a new property called device.model; this returns the specific device model, e.g. iPad2,5 (for other platforms, this returns what device.name used to return).

Update (or replace, if you never changed the file) the MainViewController.m according to the one from the new project:
- Updated → viewWillAppear
Copy the cordova directory from the new project into your project's root directory. In 2.2.0, this has an updated 'emulate' script.
Next, update the CordovaLib sub-project reference. Beginning with Cordova 2.1.0, we are not using the CORDOVALIB Xcode variable anymore when referencing where CordovaLib resides, the reference is an absolute file reference now.
1. Launch Terminal.app
2. Go to the location where you installed Cordova (see Step 1), in the bin subdirectory
3. Run the script below where the first parameter is the path to your project's .xcodeproj file:
  
  update_cordova_subproject path/to/your/project/xcodeproj

NOTE: In 2.2.0, the bin/create script copy in the CordovaLib sub-project into your project. To have the same kind of setup, just copy in the right CordovaLib into your project directory, and update the CordovaLib sub-project location (relative to the project) in the Xcode File Inspector.

Upgrading 2.0.0 Projects to 2.1.0

With Cordova 2.1.0, CordovaLib has been upgraded to use Automatic Reference Counting (ARC). You don't need to upgrade to ARC to use CordovaLib, but if you want to upgrade your project to use ARC, please use the Xcode migration wizard from the menu: Edit → Refactor → Convert to Objective-C ARC…, de-select libCordova.a, then run the wizard to completion.

Remove the VERSION file reference from your project (not the one in CordovaLib).
Next, update the CordovaLib sub-project reference. Beginning with Cordova 2.1.0, we are not using the CORDOVALIB Xcode variable anymore when referencing where CordovaLib resides, the reference is an absolute file reference now.

Search for Other Linker Flags. For that setting, append this value:
```
-weak_framework CoreFoundation
```
Build your project, it should compile and link with no issues.
Select your project from the Scheme drop-down, and then select iPhone 5.1 Simulator.
