  • iOS 11.0+

🏁 Quick start

Installation

CocoaPods

You can use CocoaPods to install Purchasely by adding it to your Podfile:

pod 'Purchasely'

Carthage

You can use Carthage to install Purchasely by adding it to your Cartfile:

binary "https://raw.githubusercontent.com/Purchasely/Purchasely-iOS/master/Purchasely.json"

Initialize the SDK

In the AppDelegate method didFinishLaunchingWithOptions initialize the SDK. This must be done at this very moment to catch the purchase requests made from the App Store directly (promoting in app purchases) or previous incomplete transactions

import Purchasely

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    Purchasely.start(withAPIKey: "API_KEY", appUserId: "USER_ID")
	return true
}

The appUserID parameter is optional and allows you to associate the purchase to a user instead of a device (see next)

Setup User Id

Once your user is logged in and you can send us a userId, please do it otherwise the purchase will be tied to the device and your user won't be able to enjoy from another device. Setting it will allow you to tie a purchase to a user to use it on other devices.

Purchasely.setAppUserId("123456789")

To remove the user (logged out) you can perform a :

Purchasely.setAppUserId(nil)

Notify when the app is ready

The SDK needs to display messages above your UI. It can be the continuation of a purchase started on the App Store, the result from a notification linking to our product, …

Your app needs to tell Purchasely SDK when it is ready to be covered by our UI.

This is done to handle cases like:

  • a loading screen that dismisses upon completion
  • an on boarding that needs to be displayed before purchasing
  • a subscribe process mandatory for app usage

When your app is ready, call the following method and the SDK will handle the continuation of whatever was in progress (purchase, push message, …)

Purchasely.isReadyToPurchase(true)

You can set it back to false when the app goes in the background when you have a screen that blocks UI in background mode and that is dismissed when the app is in foreground (like in banking apps).

Present products

Purchasely handles all the presentation logic of your products configured in the back office. You can ask for the SDK to give you the UIViewController presenting the purchase by calling the following :

// Show an activity indicator while the offer is being loaded
Purchasely.productController(for: "my_product_id", success: { [weak self](https://raw.github.com/Purchasely/Purchasely-iOS/blob/master/controller) in
	self?.present(controller, animated: true, completion: nil)
}, failure: { _ in
	// Display error and replace by your own fallback page ?
})

Since Purchasely 1.1.0 you can choose between multiple presentations by giving a presentationId :

 // Show an activity indicator while the offer is being loaded
 Purchasely.productController(for: "my_product_id", with: "my_presentation_id", success: { [weak self](https://raw.github.com/Purchasely/Purchasely-iOS/blob/master/controller) in
	 self?.present(controller, animated: true, completion: nil)
 }, failure: { _ in
	 // Display error and replace by your own fallback page ?
 })

You can be alerted if the purchase was made by listening to the Notifications

↕️ Choose how you want the offers to be presented

Once the isReadyToPurchase is set the SDK can pop windows above your UI, it can be Alerts, Product pages …

You might want to override them of chose to display them in another way. For example a side bar with the offer on iPad. You can override the default behaviors using the PLYUIDelegate.

Purchasely.setUIDelegate(self)

To change the transition, size, position … of a presented controller (PLYUIControllerType gives you the type of controller displayed):

func display(controller: UIViewController, type: PLYUIControllerType) {
	// Present the controller
}

πŸ“ˆ Integrate In App events to your analytics system

Purchasely tracks every action perfomed but you might also wish to insert these events to your own tracking system. You can receive the events (PLYEvent) by setting yourself as a delegate (PLYEventDelegate), either from the start method:

Purchasely.start(withAPIKey: "API_KEY", eventDelegate: self)

or later

Purchasely.setEventDelegate(self)

🚨 Custom error and alert views

Some information messages are also displayed to the user during the purchase life cycle like :

  • Purchase completed
  • Restoration completed

These alerts are listed in PLYAlertMessage enum.

Many errors can occure during the purchase process and are embedded in these messages liek:

  • Network error
  • Product not found
  • Purchase impossible (or canceled)
  • Restoration incomplete
  • … These errors are listed in PLYError object and translated in the supported languages of the SDK.

The SDK offers a way to display these using a standard UIAlertController message with a single Ok button to dismiss.

If you wish to offer a nicer way to display error messages, a way that reflects more your app, you can override by setting yourself as the delegate (PLYUIDelegate) you will then be responsible for displaying the messages yourself.

Purchasely.setUIDelegate(self)

That way you could also override the behaviour and trigger some specific actions when the user taps on the button for example.


func display(alert: PLYAlertMessage, error: Error?) {
	let alertTitle = alert.title
	let alertContent = alert.content ?? error?.localizedDescription
	let alertButtin = alert.buttonTitle

	// Display your modal
}

🌍 Supported languages and override messages

The SDK displays some text directly to the user (error messages, restore or login button text, …). These texts are translated in 17 languages:

  • English
  • French
  • German
  • Spanish
  • Portuguese
  • Italian
  • Czech
  • Polish
  • Greek
  • Chinese (Simplifed and traditional)
  • Japanese
  • Russian
  • Turkish
  • Swedish
  • Korean
  • Indonesian

That means that every error message and UI element will automatically translated in the user device language (if matching).

If you want to change the tone of the messages, you can override our translations and set yours. To do so, you just need to set the key and value corresponding to the message you want to change in your own Localizable.strings file. Yo ucan find the keys in one of our Localizable.strings file.

πŸ”“ Unlock content / service once a purchase is made

Once the purchase is made to Apple Servers, registered in our systems, Purchasely sends a local Notification in the NotificationCenter. You can use it to unlock the content or refresh it.

You can catch it like this

NotificationCenter.default.addObserver(self, selector: #selector(reloadContent(_:)), name: .ply_purchasedSubscription, object: nil)

And use it like that

@objc func reloadContent(_ notification: Notification) {
	// Reload the content
}

For example, this can be done in every controller that displays premium content. That way you won't have to reload the content each time the controller is displayed unless a payment was made

πŸŽ† Promote your product

… inside your app

Now everything is ready, you will want to advertise your In App Purchases from within your app to convert your users. You migh want to create banners, splash screens, … but doing it right is complex:

  • Your product is delivered in more than 150 countries and several currencies
  • Prices can change from store to store, this is not an equivalent, you can set different prices by country (cheaper in πŸ‡«πŸ‡·, more expensive in πŸ‡¬πŸ‡§) and Apple changes its price grid regularly to fit rate or taxes changes
  • You must take into account the Locale of the user to place the currency at the right spot so that the user feels safe …
  • A phone with a en-US Locale doesn't mean the user has a US App Store account. You need to interrogate the App Store to get the user price, currency, …
  • You must take into account introductory price information and display the promotion correctly ($10Β / month during 3 months ). Remember periods can be weeks, months, … but even 3 days, 2 weeksΒ and more when your intro pricing is free.

We already did that job to display your products and plans and we know it is tough, so please don't try to hardcode the pricings, periods, … Instead you can use the services we have exposed to display the pricing.

First you need to select which Plan of a product you want to expose (cheapest one ? most used ?), then you can proceed as following :

Purchasely.plan(with: "MONTHLY",
				success: { (plan) in
					// Get the regular price like "$1.99 / month"
					guard let price = plan.localizedFullPrice else { return }

					// In case there is an active promotion we display it followed by the regular price
					// for example: "$0.99 / week during 2 weeks then $1.99 / month"
					if plan.hasIntroductoryPrice,
						let introPrice = plan.localizedFullIntroductoryPrice,
						let introDuration = plan.localizedIntroductoryDuration {
						self.priceLabel.text = "\(introPrice) during \(introDuration) then \(price)"
					} else {
						self.priceLabel.text = price
					}
},
				failure: { (error) in
					// Hide advertising
})

… on the App Store

You can use the Promoting In App Purchase feature to increase the visibility of your purchases. These items are searchable on the App Store and can be purchased directly from the store.

Here is what we do for you:

  • Once a product is purchased we make sure that it won't be visible on the App Store page of your app to make more room to other products you might be selling
  • Apple says: "If you are offering an auto-renewable subscription, you’ll need to explain how auto-renewal works in the purchase flow within your app". In that case we pop the product offer once your app is started.
itms-services://?action=purchaseIntent&bundleId=APP_BUNDLE_ID&productIdentifier=IN_APP_PRODUCT_ID

Replace APP_BUNDLE_ID and IN_APP_PRODUCT_ID by the appropriate values and paste it into Notes app. Clicking on it will start a purchase action just like the App Store would.

Don't forget to add a promotional artwork following Apple Guidelines

🧾 Display your subscriptions

We believe that your customers should be able to unsubscribe as easily as they subscribed. This leads to a better global trust and offers some interesting opportunities like offering an upsell or downsell or getting to know why they choose unsubscribe.

We provide a complete active subscriptions handling flow that you can call with a single line of code and that offers:

  • Active subscriptions list
  • Next renewal date
  • Upsell / downsell
  • Cancellation survey
  • Cancellation

You can get the subscriptions list root controller by calling

Purchasely.controllerForSubscriptions()

⚠️ The controller must be added to a UINavigationController.

✍️ Manually trigger purchases

Purchasely provides presentation templates to be customized by you but if you want to create your own and only use Purchasely for handling the purchase process you can. We offer methods to:

  • Get a product
  • Get a plan
  • Get a users subscriptions
  • Purchase a product
  • Restore all products

Get a product

Purchasely.product(with: "PRODUCT_NAME", success: { (product) in
	// Display the product and its plans
}, failure: { (error) in
	// Display error
})

Get a plan

Purchasely.plan(with: "PLAN_NAME", success: { (plan) in
	// Use the plan to display a price or start a purchase
}, failure: { (error) in
	// Display error
})

Get a users subscriptions

Purchasely.userSubscriptions(success: { (subscriptions) in
	// Subscription object contains the plan purchased and the source it was purchased from (iOS or Android)
	// Calling unsubscribe() will either switch the user to its AppStore settings 
	// or display a procedure on how to unsubscribe on Android
}, failure: { (error) in
	// Display error
})

Purchase a product

Purchasely.purchase(plan: plan, success: {
	// Unlock / reload content and display a success / thank you message to user
}, failure: { (error) in
	// Display error
})

	// Reload content and display a success / thank you message to user
}, failure: { (error) in
	// Display error
})
