4 years ago Thanks for raising an issue! We've gotten a handful of questions about ResearcKit integration. Next week we will provide some sample code for you and look into how we can improve the documentation.

4 years ago Hi! Just wanted to check when you would be able to provide some sample code for this issue? Thank you!

4 years ago Thanks for your patience!
The gist of what you need to do is...
Here is an example demonstrating how to prompt the user to rate their pain on a scale of 1-10. Keep in mind as you're reading the code below that CareKit and ResearchKit both use the term "task", but that they are distinct.
// 1. Subclass a task view controller to customize the control flow and present a ResearchKit survey!
class SurveyViewController: OCKInstructionsTaskViewController, ORKTaskViewControllerDelegate {
// 2. This method is called when the use taps the button!
override func taskView(_ taskView: UIView & OCKTaskDisplayable, didCompleteEvent isComplete: Bool, at indexPath: IndexPath, sender: Any?) {
// 2a. If the task was uncompleted, fall back on the super class's default behavior or deleting the outcome.
if !isComplete {
super.taskView(taskView, didCompleteEvent: isComplete, at: indexPath, sender: sender)
return
}
// 2b. If the user attemped to mark the task complete, display a ResearchKit survey.
let answerFormat = ORKAnswerFormat.scale(withMaximumValue: 10, minimumValue: 1, defaultValue: 5, step: 1, vertical: false,
maximumValueDescription: "Very painful", minimumValueDescription: "No pain")
let painStep = ORKQuestionStep(identifier: "pain", title: "Pain Survey", question: "Rate your pain", answer: answerFormat)
let surveyTask = ORKOrderedTask(identifier: "survey", steps: [painStep])
let surveyViewController = ORKTaskViewController(task: surveyTask, taskRun: nil)
surveyViewController.delegate = self
present(surveyViewController, animated: true, completion: nil)
}
// 3. This method will be called when the user completes the survey.
// Extract the result and save it to CareKit's store!
func taskViewController(_ taskViewController: ORKTaskViewController, didFinishWith reason: ORKTaskViewControllerFinishReason, error: Error?) {
taskViewController.dismiss(animated: true, completion: nil)
guard reason == .completed else {
taskView.completionButton.isSelected = false
return
}
// 4a. Retrieve the result from the ResearchKit survey
let survey = taskViewController.result.results!.first(where: { $0.identifier == "pain" }) as! ORKStepResult
let painResult = survey.results!.first as! ORKScaleQuestionResult
let answer = Int(truncating: painResult.scaleAnswer!)
// 4b. Save the result into CareKit's store
controller.appendOutcomeValue(withType: answer, at: IndexPath(item: 0, section: 0), completion: nil)
}
}Once you have defined this view controller, you can add it into your app as you would any other CareKit view controller!
let todaysSurveyCard = SurveyViewController(
taskID: "survey",
eventQuery: OCKEventQuery(for: Date()),
storeManager: storeManager)
present(surveyCard, animated: true, completion: nil)You may also decide that you want the view to update to display the result of your survey instead of the default values used by the superclass. To change that, you can implement your own view synchronizer.
class SurveyViewSynchronizer: OCKInstructionsTaskViewSynchronizer {
// Customize the initial state of the view
override func makeView() -> OCKInstructionsTaskView {
let instructionsView = super.makeView()
instructionsView.completionButton.label.text = "Start Survey"
return instructionsView
}
// Customize how the view updates
override func updateView(_ view: OCKInstructionsTaskView,
context: OCKSynchronizationContext<OCKTaskEvents?>) {
super.updateView(view, context: context)
// Check if an answer exists or not and set the detail label accordingly
if let answer = context.viewModel?.firstEvent?.outcome?.values.first?.integerValue {
view.headerView.detailLabel.text = "Pain Rating: \(answer)"
} else {
view.headerView.detailLabel.text = "Rate your pain on a scale of 1 to 10"
}
}
}Now, when you create an instance of your SurveyViewController, you can pass in your custom view synchronizer to change how the view updates.
let surveyCard = SurveyViewController(
viewSynchronizer: SurveyViewSynchronizer(),
taskID: "survey",
eventQuery: OCKEventQuery(date: Date()),
storeManager: storeManager)
present(surveyCard, animated: true, completion: nil)Hopefully that will get you moving in the right direction. If you have any more questions, please let us know!

4 years ago Hi Erik! I've done what you mentioned about sublassing OCKInstructionsTaskViewController, but as I am using Swift UI I cannot make it a UIViewController representable since I am "redeclarating" SurveyViewController, do you know of a way of integrating a ResearchKit survey using swift ui?

3 years ago sorry if I jump in within this closed post.. I tried to integrate a survey from ResearchKit into my app, following the recommendations above, but I'm experiencing an issue: for a given date, the survey gets properly triggered and once completed, it is marked as such and can't be triggered anymore. All good so far, but when I move to a different date and I navigate back to the initial one, the survey does no longer appear in status completed, but is available again for selection. Did you experience this too? Any idea which step am I missing? (code below)
[...]
// Add survey card
let surveyCard = SurveyViewController(

}@andreaxricci If the code you provided is the actual code you're using, then it's possible problem is the date you're passing to the task view controller.
// Add survey card
let surveyCard = SurveyViewController(
viewSynchronizer: SurveyViewSynchronizer(),
taskID: "survey",
eventQuery: OCKEventQuery(for: Date()), // This should probably be `date` instead of `Date()`

It looks to me like the issue is that your survey card is looking for a task with the identifier "survey", but you have not added a task with that id to your store as part of the populateSampleData() method!

3 years ago Thanks @erik-apple! I confirm adding the task to the method helped solving the issue (I had to delete the app from the simulator and reinstall it, to refresh the store)
let survey = OCKTask(id: "survey", title: "Log data",carePlanID: nil, schedule: nauseaSchedule)
addTasks([nausea, doxylamine, kegels, survey], callbackQueue: .main, completion: nil)
I'm currently having lots of trouble integrating surveys/assessments from ResearchKit into my Care Card. I was looking through documentation on http://carekit.org/docs/docs/Overview/Overview.html#IOS, but it seems like tasks and data types related to surveys/assessments are outdated and were in the older CareKit version (in the file OCKCarePlanActivity). I'm also don't see much about this issue in the current documentation and online. Would someone be able to help me understand a good way to incorporate surveys/assessments into CareKit 2.0?
