Remember that you can collect two types of data with mParticle: event data (data about what your users are doing) and user data (data describing your users).
By default, the mParticle iOS SDK will track the following event types with no configuration required:
To track other event types, you must call the appropriate method in mParticle’s SDK directly from your app’s code whenever the event you want to track is triggered by a user.
The Higgs Shop sample app was built so that the code responsible for tracking events is as close as possible to the app components that might trigger those events. While this results in more repetitive code, the repetition is helpful for people new to the SDK.
One of the most basic events to begin tracking is when a user views different pages. We do that with the MParticle.getInstance().logScreen() method.
This method accepts the name of the screen viewed (as a string) and a list of any additional attributes (as an array).
For example, in the CartViewController.swift file we log views of the user’s cart with:
MParticle.sharedInstance().logScreen("View My Cart", eventInfo: ["number_of_products": numberOfProducts, "total_product_amounts": subTotal])Now that we’re tracking when a user visits different pages, let’s track some basic interactions using custom events.
Custom events are created with the MPEvent object, which accepts the name of an event as a string, and the event type as MPEventType.EVENT-TYPE where EVENT-TYPE can be one of several pre-defined types. This allows you to define the category of event that you are logging, like a navigation event or a search event when the user searches for an item. Event types don’t affect any functionality, but they are helpful when categorizing and organizing a large amount of data.
For a list of each custom event type, see Event Tracking.
You can also include a free-form map of custom attributes in an object called customAttributes. Custom attributes are defined as an array of key/value pairs.
The Higgs Shop uses custom events to track a range of event types. For example, in the file LandingViewController.swift, button clicks on the landing page are tracked with custom events.
if let event = MPEvent(name: "Landing Button Click", type: .other) {
MParticle.sharedInstance().logEvent(event)
}Here, an event with the name "Landing Button Click" is created with in an MPEvent object. The event type is set to .other, but no custom attributes are defined.
The event is logged to mParticle with MParticle.getInstance().logEvent(event).
Tracking commerce events involves three steps:
MPProduct, create an object that defines descriptive values like the product’s name, sku number, or price. MPTransactionAttributes, record any transaction details such as the specific product and quantity selected by a user when they add an item to their cart.MPCommerceEventAction objects. These actions are then passed into commerce events in MPCommerceEvent objects. Finally, commerce events are passed into the method MParticle.sharedInstance().logEvent(event) where event is commerce event.Products are created using MPProduct.
// 1. Create a product
let product = MPProduct(name: "Foo name", sku: "Foo sku", quantity: 4, price: 100.00)In The Higgs Shop, we create products in the file ProductDetailViewController.swift after a user has selected a product, color, and quantiy and then added the product to their shopping cart.
let mpProduct = MPProduct(name: product.label, sku: product.imageName, quantity: NSNumber(value: selectedQuantity), price: NSNumber(value: product.price))Before a commerce event can be logged in mParticle, the transaction details must be summarized, including a required transaction ID, in addition to revenue, shipping, and an optional tax.
// 2. Summarize the transaction
let attributes = MPTransactionAttributes()
attributes.transactionId = "foo-transaction-id"
attributes.revenue = 430.00
attributes.tax = 30.00When a user places an order in The Higgs Shop, the product purchaes are summarized in: CheckoutViewController.swift when a user places an order:
let transactionAttributes = MPTransactionAttributes()
transactionAttributes.transactionId = AppDelegate.transactionId
let tax = subtotal * 0.08875
let shipping = subtotal * 0.15
transactionAttributes.tax = NSNumber(value: Double(String(format: "%.2f", tax)) ?? 0)
transactionAttributes.shipping = NSNumber(value: Double(String(format: "%.2f", shipping)) ?? 0)
transactionAttributes.revenue = NSNumber(value: Double(String(format: "%.2f", subtotal + tax + shipping)) ?? 0)
event.transactionAttributes = transactionAttributesTo log a purchase event, a purchase action is created using MPCommerceEventAction.purchase. A commerce event is created using MPCommerceEvent(action: action, product: product) which receives both product and purchase action:
// 3. Log the purchase event
let action = MPCommerceEventAction.purchase;
let event = MPCommerceEvent(action: action, product: product)
event.transactionAttributes = attributes
MParticle.sharedInstance().logEvent(event)In the Higgs Shop, purchase events are logged in the same function that we created our transaction attributes CheckoutViewController.swift:
@objc private func placeOrder() {
print("place order")
if let event = MPCommerceEvent(action: .purchase) {
var products = [MPProduct]()
var subtotal = 0.0
for cartItem in AppDelegate.cart.items {
let product = cartItem.product
let mpProduct = MPProduct(name: product.label, sku: product.imageName, quantity: NSNumber(value: cartItem.quantity), price: NSNumber(value: product.price))
let attributes = NSMutableDictionary()
if cartItem.color != "N/A" {
attributes.setObject(cartItem.color, forKey: NSString("color"))
}
if cartItem.size != "N/A" {
attributes.setObject(cartItem.size, forKey: NSString("size"))
}
mpProduct.setUserDefinedAttributes(attributes)
products.append(mpProduct)
subtotal += cartItem.totalAmount
}
event.addProducts(products)
let transactionAttributes = MPTransactionAttributes()
transactionAttributes.transactionId = AppDelegate.transactionId
let tax = subtotal * 0.08875
let shipping = subtotal * 0.15
transactionAttributes.tax = NSNumber(value: Double(String(format: "%.2f", tax)) ?? 0)
transactionAttributes.shipping = NSNumber(value: Double(String(format: "%.2f", shipping)) ?? 0)
transactionAttributes.revenue = NSNumber(value: Double(String(format: "%.2f", subtotal + tax + shipping)) ?? 0)
event.transactionAttributes = transactionAttributes // transaction attributes are required
event.shouldBeginSession = AppDelegate.eventsBeginSessions
MParticle.sharedInstance().logEvent(event)
// Clear the cart
AppDelegate.cart.items.removeAll()
// Present Purchase Confirmation
let purchaseMessage = UIAlertController(title: NSLocalizedString("Purchase Complete", comment: ""), message: NSLocalizedString("No actual purchase has been made.", comment: ""), preferredStyle: .alert)
let okAction = UIAlertAction(title: "OK", style: .default, handler: { (_) -> Void in
self.navigationController?.popViewController(animated: true)
})
purchaseMessage.addAction(okAction)
self.present(purchaseMessage, animated: true, completion: nil)
}
