Advanced configurations

Manually initialize the SDK

By default, the DriveKit SDK is automatically initialized as soon as you add the TripAnalysis module to your project.

In some cases, you may want to manually initialize the SDK. To do this, you have to disable the automatic initialization by adding the key DKAutoInitEnabled associated to the Boolean value false into the Info.plist file:

Info.plist

<key>DKAutoInitEnabled</key>
<false/>

Then, you must call the initialization method in didFinishLaunchingWithOptions method of your AppDelegate.

AppDelegate

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    DriveKit.shared.initialize()
    DriveKitTripAnalysis.shared.initialize(appLaunchOptions: launchOptions)
    (…)
}

The DriveKit modules include a method initialize that must be called in didFinishLaunchingWithOptions method of your AppDelegate if you have decided to manually initialize the SDK.

Check your configuration

You can check if DriveKit is well configured with the following method:

DriveKit

func isConfigured() -> Bool

This method returns true if these three conditions are met:

• DriveKit Core is initialized

• an API key is set

• a userId is set

Logging

DriveKit comes with a logging feature that is enabled by default. This feature allows you to quickly identify the cause of a problem. We recommend leaving the log enabled as it does not consume memory space and is useful in the support phase. However, if you don't want to use it, it can be disabled.

Log will be written in app directory. One log file per month will be written with the name log-<YEAR>-<MONTH>.txt (example: log-2019-8.txt). All DriveKit modules log in this file. You can get a zip file with the log files of the previous month and the current one with the method DriveKitLog.shared.getZippedLogFilesUrl(), or by clicking on “Contact support” and changing the email receiver. The file will be in attachment of the email.

You can also make files of your application (including DriveKit log files) available in the iOS Files app by adding these 2 keys to your project's Info.plist file: UIFileSharingEnabled and LSSupportsOpeningDocumentsInPlace, setting them both to true.

To be able to access logs from Files app, you must add the following entries in your Info.plist file: UIFileSharingEnabled and LSSupportsOpeningDocumentsInPlace, setting both to true.

Disable logging by calling the following method:

DriveKit

func disableLogging(showInConsole: Bool = true)

To activate logging, call the following method:

DriveKit

func enableLogging(showInConsole: Bool = true)

Listen for permissions and sensors status changes

If the user disables the sensors or revokes permissions, the application would not be able to detect and record a trip. To avoid this, the SDK identifies important sensor state and permission changes.

These events are shared and you can use them in your application to inform the user via a visual alert or by displaying a notification.

Event changes callbacks may not be fired in real time due to technical restrictions of iOS.

DKDeviceConfigurationDelegate

DKDeviceConfigurationDelegate is a protocol used to get callbacks when device configuration changes are detected:

protocol DKDeviceConfigurationDelegate: AnyObject {
    func deviceConfigurationDidChange(event: DKDeviceConfigurationEvent)
}

Add a delegate

To add a delegate and listen for Device Configuration Events, you can call the following function:

DriveKit

func addDeviceConfigurationDelegate(_ delegate: DKDeviceConfigurationDelegate)

Remove a delegate

To remove a specific delegate, call the following method:

DriveKit

func removeDeviceConfigurationDelegate(_ delegate: DKDeviceConfigurationDelegate)

Remove all delegates

To remove all delegates, call the following method:

DriveKit

func removeAllDeviceConfigurationDelegates()

DKDeviceConfigurationEvent

DKDeviceConfigurationEvent is a class describing a device configuration event.

class DKDeviceConfigurationEvent {
    let type: DKDeviceConfigurationEventType
    let isValid: Bool
}

Attribute	Type	Description
type	Enum	DKDeviceConfigurationEventType enum describing the type of event
isValid	Boolean	Boolean describing whether the device configuration event is valid or not

DKDeviceConfigurationEventType

public enum DKDeviceConfigurationEventType {
    case activityPermission
    case locationPermission
    case bluetoothPermission
    case notificationPermission
    case lowPowerMode
    case locationSensor
    case bluetoothSensor
}

Possible types are:

Event type	Description
activityPermission	Motion & Fitness permission status changed
locationPermission	Location permission status changed
bluetoothPermission	Bluetooth permission status changed
notificationPermission	Notifications permission status changed
lowPowerMode	Low Power Mode status changed
locationSensor	Location sensor status changed
bluetoothSensor	Bluetooth sensor status changed

The DriveKit SDK will run optimally if the isValid value of each event is true. The table below explains the impact of a status that is not true.

Event	Criticality	Consequence if value is false
LocationPermission	🔴	No trip recording if app has no access to GPS sensor
BluetoothPermission	🟡	No trip detection based on Bluetooth system
ActivityPermission	🟡	Detected transportation mode mode can be inaccurate when no access to this permission
NotificationPermission	🟢	Your application cannot send notification to the user if the permission is revoked.
lowPowerMode	🟢	No considerable impact
LocationSensor	🔴	No trip recording if GPS sensor is disabled
BluetoothSensor	🟡	No trip detection based on Bluetooth system. Can also impact beacon trip detection.

Get user’s information

To get user’s information (first name, last name and pseudo), call the getUserInfo method. It will retrieve and save these data locally:

DriveKit.shared.getUserInfo(synchronizationType: .defaultSync) { status, userInfo in
    if status == .success {
        // Get user's names in userInfo object.
    }
}

Update user’s information

You can add information to a user's account such as first name, last name and pseudo. These details are optional and you can choose to make the user's account anonymous. To update the user's information, you must call the updateUserInfo method:

DriveKit.shared.updateUserInfo(pseudo: "New_pseudo") { success in
    if success {
        // The pseudo has been successfully updated.
    }
}

Or to update all information:

DriveKit.shared.updateUserInfo(firstname: "New_firstname", lastname: "New_lastname", pseudo: "New_pseudo") { success in
    if success {
        // The firstname, lastname and pseudo have been successfully updated.
    }
}

Update UserId

It is possible to update the userId by calling the following method:

DriveKit

func updateUserId(userId: String)

To be able to check whenever userId got updated and catch the update status, you have to use DriveKitDelegate delegate.

Account deletion

You can delete a driver's account in DriveKit. This action deletes all the data related to the account.

The deletion can be done instantly or with delay.

• In the first case, when the method is called, the account is instantly deleted.

• In the second case, the driver has 30 days to log back into the application and reactivate his account.

To delete a driver's account, use the following method:

DriveKit

func deleteAccount(instantDeletion: Bool = false)

instantDeletion can have 2 values:

• false : Default value, allows the user to recover the deleted account by logging-in again with the same credentials. Users have 30 days starting from the day when the account was deleted.

• true : Allow to delete an account instantly. The account and all the related data will be immediately deleted and no rollback is possible.

Your team needs to have the deletion feature activated to use this method. Please contact DriveQuant if you need it.

To be able to check whenever the account deletion is complete, you have to use the DriveKitDelegate interface.

You should restore the DriveKit API key in the onAccountDeleted() callback only when the status value is SUCCESS.

Reset

If you need to reset DriveKit configuration (user logout for example), you can call the following method:

DriveKit.shared.reset()

All data saved locally will be erased and default configuration for every module will be restored.
