What’s new in Cordova iOS 2.3.0

with 40 comments

cordova_bot

1. iOS 5.x and above support only

We are dropping iOS 4.x support and only supporting iOS 5.0 and greater, going forward.

2. Cordova.plist is changed to config.xml

The configuration Cordova.plist file has been changed to config.xml – it comes in a new format that is the same as the Android config.xml. If you are upgrading, you will need to convert your existing Cordova.plist by running the bin/cordova_plist_to_config_xml script. The 2.3.0 project itself will warn you (in the console log) if you are still using the old Cordova.plist and tell you to upgrade.

The new project settings are documented here.

An example config.xml:

<cordova>
        <preference name="MySetting" value="true" />
        <plugins>
            <plugin name="MyPlugin" value="MyPluginClass" />
        </plugins>
        <access origin="*" />
</cordova>

3. InAppBrowser – includes events

More details here. In a nutshell, this has the same functionality as the ChildBrowser, and has events support as well. It supports this simplified spec. Also, the InAppBrowser does not use the app whitelist. Example usage:


var ref = window.open('http://google.com', '_blank');
ref.addEventListener('loadstart', function(event) { alert(event.type + ' - ' + event.url); } );
ref.addEventListener('loadstop', function(event) { alert(event.type + ' - ' + event.url); } );
ref.addEventListener('exit', function(event) { alert(event.type); } );

// also, you can do ref.removeEventListener('loadstart', myfunc) .. etc

4. LocalNotification  plugin event, AppDelegate override

Your project’s AppDelegate.m can add a new AppDelegate override so your plugins can receive LocalNotification events. Uncomment these lines  to enable your plugin to receive the notifications in their overrides.

5. Renaming of Cordova cli commands

The new list of commands are here. Basically debug has been renamed to build, and new release,  and run commands have been added. This is common across all the platforms.

6. Objective-C plugins are not white-listed anymore

With the InAppBrowser release, we restructured the whitelist to only apply to the main Cordova WebView. As a consequence, the whitelist does not apply to all connections for the app, thus connections from your plugins are not whitelisted. To whitelist your connections with the app whitelist, you will 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 will pass the whitelist. See this guide.

7. Device API changes

Minor changes as specified here. 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).

8. CommandDelegate overrides

The command delegate could not be overriden properly, now fixed. Please look at this issue on how to override the delegate functions, for inspection.

Check out the Release Notes for other minor changes.

InAppBrowser (based on ChildBrowser) in Cordova 2.3.0

The inclusion of the InAppBrowser in iOS and Android will be new for Cordova 2.3.0. You can play with the InAppBrowser today if you download the latest code and help us test.

The InAppBrowser is a built-in web browser for your app that has an API that follows web standards. It follows the window.open API, except for a new window target that we introduced: “_system“. Read our simple specification.

Does this mean the ChildBrowser is going away? Not really. These two plugins can co-exist, and ChildBrowser has added features that are not present in the InAppBrowser, particularly events. [UPDATE: see below]InAppBrowser also has no dependencies on a .xib or external images, so it is easy to integrate for upgrades.

What’s also new with the InAppBrowser implementation for iOS is, the white-list is not applied application wide anymore, the white-list will only apply for the main Cordova UIWebView only. Now you can load non-white-listed URLs into the InAppBrowser and the ChildBrowser.

There are several enhancements for plugins related to this new white-list exception functionality as well – please see issue CB-1889. The enhancements should land before the final 2.3.0 is released.

Please help us test by downloading the latest code or RC and giving this new feature a spin!

[Update Nov 28 2012]: The InAppBrowser on iOS has support for events now (Android in progress). You can listen to the ‘loadstart‘, ‘loadstop‘ and ‘exit‘ events. The callback function is passed an event object that has two properties: type, and url. You will need to grab the latest code and javascript (create a new project).

Example usage:

var ref = window.open('http://google.com', '_blank');
ref.addEventListener('loadstart', function(event) { alert(event.type + ' - ' + event.url); } );
ref.addEventListener('loadstop', function(event) { alert(event.type + ' - ' + event.url); } );
ref.addEventListener('exit', function(event) { alert(event.type); } );

// also, you can do ref.removeEventListener('loadstart', myfunc) .. etc

[Update Nov 30 2012]: Changes for InAppBrowser events for Android are in cordova-android now.

[Update Jan 7 2013]: If you have a multi-page app, and you use InAppBrowser, and you use iOS 6, you must use iframe bridge mode. More details here.

What’s new in Cordova iOS 2.2.0

with 58 comments

1. Set Xcode 4.5 minimum (iOS 6 SDK, iOS 4.3 deployment target, no armv6)

Submission to the Apple App Store requires the latest SDK, which is iOS 6. The iOS 6 SDK only comes with Xcode 4.5. Xcode 4.5 drops support for armv6, thus the minimum deployment target supported is iOS 4.3. This means that support for the iPhone 3G, and iPod Touch 2nd Generation is dropped.

2. Fixed iOS 6 and iPhone 5 issues

  1. iOS 6 Contacts permissions support – this was the only API issue for iOS 6 that did not make it into 2.1.0
  2. Capture API – for capturing audio, a new microphone image has been added for the iPhone 5 dimensions, and the Capture API view controllers support the new iOS 6 orientation delegate methods
  3. Added iPhone 5 sized Splash Screen
  4. Added new iOS 6 orientation delegate methods, and fixed orientation bug: http://issues.cordova.io/1465
  5. iOS 6 LocalStorage changes (backup flag), see issue http://issues.cordova.io/1561 and new Cordova.plist setting change to allow for iCloud, local or no backup. 

3. FileTransfer API changes

  1. Added support for the onprogress event to get progress events for a FileTransfer operation
  2. Added the abort function to cancel a FileTransfer operation

See the API doc.

4. Cordova.plist new properties, and changed a property

  1. Added the iOS 6 property SuppressesIncrementalRendering – set to YES (defaults to NO) to wait until all new view content has been received before it is rendered.
  2. Added the iOS 6 property KeyboardDisplayRequiresUserAction – set to NO (defaults to YES) to open the keyboard when form elements get focus via JavaScript focus() call.
  3. Changed the property BackupWebStorage (string, defaults to ‘cloud’) – valid values are ‘none’, ‘cloud’ and ‘local’. Set to ‘cloud’ to allow the web storage data to be backed up to iCloud, and set to ‘local’ to only allow local backups (iTunes sync). Set to ‘none’ to not allow any backups of web storage. The previous boolean property is deprecated and mapped to ‘cloud’ (true) and ‘none’ (false).

See the Project Settings doc.

5. Graduated the Globalization plugin to core

This plugin was previously in the phonegap-plugins repo (BB WebWorks 5, iOS, Android). The globalization object obtains information and performs operations specific to the user’s locale and timezone.

See the API doc.

6. bin/create script changes

In 2.2.0 by default, the CordovaLib sub-project is copied into your project folder. Previously the CordovaLib sub-project was linked in to your project as a shared project. To still use a shared CordovaLib, add “–shared” as the first parameter to bin/create. This is useful for committers to just point to the CordovaLib from their git repo.

7. uncrustify hook for committers

Uncrustify is a utility that beautifies your code — essentially it enforces certain code formatting conventions. Right now it is only added to the iOS repo as a trial. See the issue: http://issues.cordova.io/625

In the root of your iOS repo, using the command line:

cd .git
rm -r hooks
ln -s ../hooks .

Otherwise, you should run the bin/uncrustify.sh command manually before checking in code on iOS.

8. onReset() override for plugins

Add a onReset() method to your plugin — this is called on top-level navigation or refresh, so that plugins can know to cancel any long-running requests and reinitialize themselves. This is for the situation where your WebView has been refreshed, and any operations and callbacks for plugins are invalid.

9. iOS JavaScript-Obj-C bridge improvements

  1. no longer broken for non file:// pages
  2. No longer shows failed requests in the remote web inspector
  3. 15% speed improvement in benchmarks

10. Splashscreen API

The Splashscreen API is now formally documented for iOS and Android.
