iOS In-App Purchase plugin

By Matt Kane

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

Adding the Plugin to your project

Copy the .h and .m file to the Plugins directory in your project. Copy the .js file to your www directory and reference it from your html file(s). Finally, add StoreKit.framework to your Xcode project if you haven't already.

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.

The plugin creates the object window.plugins.inAppPurchaseManager with the following methods:

requestProductData(productId, successCallback, failCallback)

makePurchase(productId, quantity)

restoreCompletedTransactions()

You can also register the following callbacks:

window.plugins.inAppPurchaseManager.onPurchased = function(transactionIdentifier, productId, transactionReceipt) {}

window.plugins.inAppPurchaseManager.onRestored = function(originalTransactionIdentifier, productId, originalTransactionReceipt) {}

window.plugins.inAppPurchaseManager.onFailed = function(errorCode, errorText);

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 requestProductData to retrieve the localised product data. If you don't do this, then any attempt to make a purchase will fail. A basic usage example is below:

	window.plugins.inAppPurchaseManager.onPurchased = function(transactionIdentifier, productId, transactionReceipt) {
		console.log('purchased: ' + productId);
		/* Give coins, enable subscriptions etc */
	}

	window.plugins.inAppPurchaseManager.onRestored = function(transactionIdentifier, productId, transactionReceipt) {
		console.log('restored: ' + productId);
		/* See the developer guide for details of what to do with this */
	}

	window.plugins.inAppPurchaseManager.onFailed = function(errno, errtext) {
		console.log('failed: ' + errtext);
	}

	window.plugins.inAppPurchaseManager.requestProductData("com.example.test", function(productId, title, description, price) {
    		console.log("productId: " + productId + " title: " + title + " description: " + description + " price: " + price);
    		window.plugins.inAppPurchaseManager.makePurchase(productId, 1);
    	}, function(id) {
    		console.log("Invalid product id: " + id);
	    }
	);
