Usage
Configuration
Before sending timers you must first configure BlueTriangle
. It is recommended to do this in your AppDelegate.application(_:didFinishLaunchingWithOptions:)
method:
BlueTriangle.configure { config in
config.siteID = "MY_SITE_ID"
config.isReturningVisitor = true
config.abTestID = "MY_AB_TEST_ID"
config.campaignMedium = "MY_CAMPAIGN_MEDIUM"
config.campaignName = "MY_CAMPAIGN_NAME"
config.campaignSource = "MY_CAMPAIGN_SOURCE"
config.dataCenter = "MY_DATA_CENTER"
config.trafficSegmentName = "MY_SEGMENT_NAME"
config.crashTracking = .nsException
config.performanceMonitorSampleRate = 1.0
}
Timers
To measure the duration of a user interaction, initialize a Page
object describing that interaction and pass it to BlueTriangle.startTimer(page:timerType)
to receive a running timer instance.
let page = Page(pageName: "MY_PAGE")
let timer = BlueTriangle.startTimer(page: page)
If you need to defer the start of the timer, pass your Page
instance to BlueTriangle.makeTimer(page:timerType)
and call the timer's start()
method when you are ready to start timing:
let page = Page(pageName: "MY_PAGE")
let timer = BlueTriangle.makeTimer(page: page)
...
timer.start()
In both cases, pass your timer to BlueTriangle.endTimer(_:purchaseConfirmation:)
to send it to the Blue Triangle server.
BlueTriangle.endTimer(timer)
Running timers are automatically stopped when passed to BlueTriangle.endTimer(_:purchaseConfirmation:)
, though you can end timing earlier by calling the timer's end()
method.
timer.end()
...
// You must still pass the timer to `BlueTriangle.endTimer(_:)` to send it to the Blue Triangle server
BlueTriangle.endTimer(timer)
For timers that are associated with checkout, create a PurchaseConfirmation
object to pass along with the timer to BlueTriangle.endTimer(_:purchaseConfirmation:)
:
timer.end()
let purchaseConfirmation = PurchaseConfirmation(cartValue: 99.00)
BlueTriangle.endTimer(timer, purchaseConfirmation: purchaseConfirmation)
Timer Types
BlueTriangle.makeTimer(page:timerType:)
and BlueTriangle.startTimer(page:timerType:)
have a timerType
parameter to specify the type of the timer they return. By default, both methods return main timers with the type BTTimer.TimerType.main
. When network capture is enabled, requests made with one of the bt
-prefixed URLSession
methods will be associated with the last main timer to have been started at the time the request completes. It is recommended to only have a single main timer running at any given time. If you need overlapping timers, create additional custom timers by specifying a BTTimer.TimerType.custom
timer type:
let mainTimer = BlueTriangle.startTimer(page: Page(pageName: "MY_PAGE"))
let customTimer = BlueTriangle.startTimer(page: Page(pageName: "MY_OTHER_TIMER"), timerType: .custom)
// ...
BlueTriangle.endTimer(mainTimer)
// ...
BlueTriangle.endTimer(customTimer)
Network Capture
The Blue Triangle SDK supports capturing network requests using either the NetworkCaptureSessionDelegate
or bt
-prefixed URLSession
methods.
To enable network capture, first configure the SDK with a non-zero network sample rate:
BlueTriangle.configure { config in
...
config.networkSampleRate = 0.05
}
A value of 0.05
, for example, means that network capture will be randomly enabled for 5% of user sessions. Network requests using a URLSession
with a NetworkCaptureSessionDelegate
or made with one of the bt
-prefixed URLSession
methods will be associated with the last main timer to have been started at the time a request completes. Note that requests are only captured after at least one main timer has been started and they are not associated with a timer until the request ends.
NetworkCaptureSessionDelegate
You can use NetworkCaptureSessionDelegate
or a subclass as your URLSession
delegate to gather information about network requests when network capture is enabled:
let sesssion = URLSession(
configuration: .default,
delegate: NetworkCaptureSessionDelegate(),
delegateQueue: nil)
let timer = BlueTriangle.startTimer(page: Page(pageName: "MY_PAGE"))
...
let (data, response) = try await session.data(from: URL(string: "https://example.com")!)
URLSession
Methods
Alternatively, use bt
-prefixed URLSession
methods to capture network requests:
Standard | Network Capture |
---|---|
URLSession.dataTask(with:completionHandler:) |
URLSession.btDataTask(with:completionHandler:) |
URLSession.data(for:delegate:) |
URLSession.btData(for:delegate:) |
URLSession.dataTaskPublisher(for:) |
URLSession.btDataTaskPublisher(for:) |
Use these methods just as you would their standard counterparts:
let timer = BlueTriangle.startTimer(page: Page(pageName: "MY_PAGE"))
...
URLSession.shared.btDataTask(with: URL(string: "https://example.com")!) { data, response, error in
// ...
}.resume()
Screen View Tracking
All UIViewControllers view count can be tracked. Setting "enableScreenTracking" configuration property to true will capture view counts of every UIViewController in your app. You can see each view controller name with there count on our dashboard.
BlueTriangle.configure { config in
...
config.enableScreenTracking = true
}
SwiftUI views are not captured automatically. You need to call bttTrackScreen() modifier on each view which you want to track. Below example show usage of "bttTrackScreen(_ screenName: String)" to track About Us screen.
struct ContentView: View {
var body: some View {
VStack{
Text("Hello, world!")
}
.bttTrackScreen("Demo_Screen")
}
}
ANR Detection
ANR(Application Not Responding) detects to main thread in which an app becomes unresponsive or stops responding to user input for an extended period of time. It can be enabled by setting "ANRMonitoring" configuration property to "true". And it can set Interval, to consider it an ANR situation by setting "ANRWarningTimeInterval" configuration property as shown below.
BlueTriangle.configure { config in
...
config.ANRMonitoring = true
config.ANRWarningTimeInterval = 3
}
By default, the ANR interval is set to 5 seconds.
