iOS In-App Purchase plugin

• Allows In-App Purchases to be made from a Phonegap Application.
• Wraps StoreKit.

Original code: Matt Kane

Maintainer: Jean-Christophe Hoelt

Install the Plugin

PhoneGap/Cordova >= 3.0

For PhoneGap >= 3.0 this plugin can be installed with a single command:

phonegap local add git://github.com/j3k0/PhoneGap-InAppPurchase-iOS.git

And that's for Cordova:

cordova plugin add git://github.com/j3k0/PhoneGap-InAppPurchase-iOS.git

PhoneGap <= 2.9 using Plugman

plugman install --platform ios --project <path to Xcode project> --plugin git://github.com/j3k0/PhoneGap-InAppPurchase-iOS.git

See Cordova Plugman.

**NOTE: If you plan on using the cordova-cli to build your project, copy the cordova_plugins.js file in the root of the www directory to merges/ directory at the root of the solution folder otherwise the cordova_plugins.js will be overwritten.

cp ./cordova_plugins.js ../../../merges/ios/cordova_plugins.js

See Cordova Cli.

Manually

• Copy the .h and .m file from src/ios/ to the Plugins directory in your Xcode project.
• Create a plugins folder in your project's <path to Xcode project>/www folder if it does not exist.
• Create a com.phonegap.plugins.inapppurchase folder inside the plugins folder.
• Copy InAppPurchase.js into <path to Xcode project>/www/plugins/com.phonegap.plugins.inapppurchase
• Add the following to the config.xml file in your Xcode project:

    <feature name="InAppPurchase">
       <param name="ios-package" value="InAppPurchase" />
    </feature>

• Add the following to the config.xml file in your Xcode project:
• Create a new file named cordova_plugins.js in the <path to Xcode project>/www folder if it does not exist.
• Edit cordova_plugins.js and add a reference to the plugin to automatically load it:

    cordova.define('cordova/plugin_list', function(require, exports, module) {
    module.exports = [
        {
            "file": "plugins/com.phonegap.plugins.inapppurchase/InAppPurchase.js",
            "id": "com.phonegap.plugins.inapppurchase.InAppPurchase",
            "clobbers": [
                "storekit"
	    ]
    	}
    ]
    });

Using the plugin

NOTE: In-app purchases can be complicated, with very unhelpful error messages and lots of things that need to be configured perfectly for them to work. I cannot provide support for them. Errors are highly unlikely to have been caused by the plugin. Please see the Apple Developer Forums for help!

Please read the In-App Purchase Programming Guide and the iTunes Connect Developer Guide.

Documentation

NOTE: For more detailed information about these methods see the InAppPurchaseManager.js file.

The plugin adds the window.storekit object, with the following methods:

storekit.init({
    debug: true,
    ready:    function () {},
    error:    function (errorCode, errorText) {},
    purchase: function (transactionId, productId) {},
    restore:  function (originalTransactionId, productId) {}
    restoreCompleted: function () {},
    restoreFailed:    function (errorCode) {}
})
storekit.load(productIds, callback)
storekit.restore()
storekit.purchase(productId, quantity)

You should register the callbacks early in your app's initialisation process, because StoreKit will automatically attempt to complete any unfinished transactions when you launch the app. If the plugin does receive callbacks before you have registered a handler, they will be placed into a queue and executed when you do register one.

Before attempting to make a purchase you should first call load to retrieve the localised product data. If you don't do this, then any attempt to make a purchase will fail.

Here's a basic usage example:

In your deviceready listener, call:

window.storekit.init({

    debug: true, /* Because we like to see logs on the console */

    purchase: function (transactionId, productId) {
        console.log('purchased: ' + productId);
    },
    restore: function (transactionId, productId) {
        console.log('restored: ' + productId);
    },
    restoreCompleted: function () {
       console.log('all restore complete');
    },
    restoreFailed: function (errCode) {
        console.log('restore failed: ' + errCode);
    },
    error: function (errno, errtext) {
        console.log('Failed: ' + errtext);
    },
    ready: function () {
        var productIds = [
            "com.example.app.inappid1", 
            "com.example.app.inappid2"
        ];
        window.storekit.load(productIds, function(validProducts, invalidProductIds) {
            $.each(validProducts, function (i, val) {
                console.log("id: " + val.id + " title: " + val.title + " val: " + val.description + " price: " + val.price);
            });
            if(invalidProductIds.length) {
                console.log("Invalid Product IDs: " + JSON.stringify(invalidProductIds));
            }
        });
    }
});

To restore previous purchases:

window.storekit.restore();

To make a purchase:

window.storekit.purchase("com.example.app.inappid1", 1);

Advanced use

Receipts

window.storekit.loadReceipts(function (receipts) {
    receipts.appStoreReceipt(); // null or base64 encoded receipt (iOS >= 7)
    receipts.forTransaction(transactionId); // null or base64 encoded receipt (iOS < 7)
    receipts.forProduct(productId); // null or base64 encoded receipt (iOS < 7)
});

Manually Finish Transactions

By default, the plugin auto-finish all completed transactions. In some cases, for example when content needs to be delivered by a server, you should finish the transaction only when the content has been delivered. (Thus preventing the user from paying for something he didn't get).

To achieve this, set the noAutoFinish option to true in init(). Then you shoud call window.storekit.finish(transactionId) whenever content is delivered for a given purchase.

Example:

storekit.init({
    noAutoFinish: true,
    purchase: function (transactionId, productId) {
        if (productId === '42.mp3') {
            myDownload('http://x.yz/42.mp3', function () {
                storekit.finish(transactionId);
            });
        }
    },
    finish: function (transactionId, productId) {
        // Called when a transaction has been finished.
    }
});
storekit.purchase(productId, quantity)

Test your IAP

The plugin offers a way for you to check if your IAP should work.

Run the following command and follow the instructions:

./test/run.sh
