如何在ResearchKit中制作调查结果的pdf文件

Question

我正在做这个代码，并坚持使pdf与调查结果。谁能帮忙把调查任务的结果做成pdf文件?提前谢谢。

 func taskViewController(taskViewController: ORKTaskViewController,
    didFinishWithReason reason: ORKTaskViewControllerFinishReason,
    error: NSError?) {
        let taskResult = taskViewController.result
        if reason  == ORKTaskViewControllerFinishReason.Completed
        {
           // var data = NSKeyedArchiver.archivedDataWithRootObject(taskViewController.result)
            //here how can i get the text of steps and results?
            NSUserDefaults.standardUserDefaults().setBool(true, forKey: kSurveyCompleted)
            NSUserDefaults.standardUserDefaults().synchronize()
        }
        if reason  == ORKTaskViewControllerFinishReason.Discarded
        {
            NSUserDefaults.standardUserDefaults().setBool(false, forKey: kSurveyCompleted)
            NSUserDefaults.standardUserDefaults().synchronize()
        }

}

你可以这样使用pdf库:https://github.com/techprimate/TPPDF很容易在PDF中创建一个表，并用字段/值行填充它。如果你用的是iOS 11，里面有PDFKit
