我对结果表调查的类型有疑问。如果我使用 CareKit / HealthKit 调查，一切都很好，当我想将它与 ResearchKit 调查混合时 - 我在以下方法中有错误：
func buildCarePlanResultFrom(taskResult: ORKTaskResult) -> OCKCarePlanEventResult {
guard let firstResult = taskResult.firstResult as? ORKStepResult,
let stepResult = firstResult.results?.first else {
fatalError("Unexepected task results")
}
if let numericResult = stepResult as? ORKNumericQuestionResult,
let answer = numericResult.numericAnswer {
return OCKCarePlanEventResult(valueString: answer.stringValue, unitString: numericResult.unit, userInfo: nil)
} else {
}
fatalError("Unexpected task result type")
}
这是 - 我认为 - 因为我无法制作 OCKCarePlanEventResult 对象 [answer 和 numericResult 都是 nil]。
我在下面的扩展中更新了症状跟踪器：
extension TabBarViewController: ORKTaskViewControllerDelegate {
func taskViewController(_ taskViewController: ORKTaskViewController, didFinishWith
reason: ORKTaskViewControllerFinishReason, error: Error?) {
defer {
dismiss(animated: true, completion: nil)
}
guard reason == .completed else { return }
guard let symptomTrackerViewController = symptomTrackerViewController,
let event = symptomTrackerViewController.lastSelectedAssessmentEvent else { return }
symptomTrackerViewController.progressRingTintColor = .lightGreen
symptomTrackerViewController.delegate = self
let carePlanResult = carePlanStoreManager.buildCarePlanResultFrom(taskResult: taskViewController.result)
carePlanStoreManager.store.update(event, with: carePlanResult, state: .completed) {
success, _, error in
if !success {
print(error?.localizedDescription)
}
}
}}
有什么建议如何将 ResearchKit 的结果类型转换为 CareKit 或其他解决方案以更新视图？
可能，这会有所帮助，任务示例：
let sleepHoursSurveyActivity = OCKCarePlanActivity.assessment(
withIdentifier: ActivityIdentifier.sleepHours.rawValue,
groupIdentifier: nil,
title: "Sleep Hours",
text: nil,
tintColor: .darkGreen,
resultResettable: true,
schedule: dailyScheduleRepeating(occurencesPerDay: 1),
userInfo: ["ORKTask" : AssessmentTaskFactory.sleepHoursSurveyAssessmentTask()])
static func sleepHoursSurveyAssessmentTask() -> ORKTask {
var steps = [ORKQuestionStep]()
let question = NSLocalizedString("How many hours did you sleep?", comment: "")
let textChoices = [
ORKTextChoice(text: "1-3", value: "1-3" as NSString),
ORKTextChoice(text: "4-5", value: "4-5" as NSString),
ORKTextChoice(text: "6-7", value: "6-7" as NSString),
ORKTextChoice(text: "8", value: "8" as NSString),
ORKTextChoice(text: "more than 8", value: "more than 8" as NSString)
]
let questAnswerFormat: ORKTextChoiceAnswerFormat = ORKAnswerFormat.choiceAnswerFormat(with: .singleChoice, textChoices: textChoices)
let sleepHoursSurvaySteps = ORKQuestionStep(identifier: "sleepHours", title: question, answer: questAnswerFormat)
sleepHoursSurvaySteps.isOptional = false
steps += [sleepHoursSurvaySteps]
return ORKOrderedTask(identifier: "sleepHoursSurveyTask", steps: [sleepHoursSurvaySteps])
}
