我正在使用SwiftUI编写供个人使用的研究套件应用程序,我想知道如何与Modal View打开的研究套件调查任务进行交互。
此刻我正在使用以下代码打开视图:
struct SurveyView: UIViewControllerRepresentable {
typealias UIViewControllerType = ORKTaskViewController
func makeUIViewController(context: Context) -> ORKTaskViewController {
let taskViewController = ORKTaskViewController(task: SurveyTask, taskRun: nil)
taskViewController.view.tintColor = UIColor(red:0.64, green:0.15, blue:0.11, alpha:1.00)
return taskViewController
}
func updateUIViewController(_ taskViewController: ORKTaskViewController, context: Context) {
}
}
我正在使用一个按钮来调用它,但是我无法使用研究工具包中的“取消”或“完成”按钮将其关闭,因为我不清楚应该在何处实现didFinishWithReason reason: ORKTaskViewControllerFinishReason
。
任何帮助将不胜感激。

我已经设法使用协调器做到了。如果有人感兴趣,这里是代码。
struct SurveyView: UIViewControllerRepresentable {
func makeCoordinator() -> Coordinator {
Coordinator()
}
typealias UIViewControllerType = ORKTaskViewController
func makeUIViewController(context: Context) -> ORKTaskViewController {
let taskViewController = ORKTaskViewController(task: SurveyTask, taskRun: nil)
taskViewController.view.tintColor = UIColor(red:0.64, green:0.15, blue:0.11, alpha:1.00)
taskViewController.delegate = context.coordinator
return taskViewController
}
func updateUIViewController(_ taskViewController: ORKTaskViewController, context: Context) {
}
class Coordinator: NSObject, ORKTaskViewControllerDelegate {
func taskViewController(_ taskViewController: ORKTaskViewController, didFinishWith reason: ORKTaskViewControllerFinishReason, error: Error?) {
taskViewController.dismiss(animated: true, completion: nil)
}
}
}
