无法将数据从一个视图控制器推送到表视图控制器

Question

I ran into a strange problem while I was working on my project. (Please bear with me, I'm a Swift beginner.)

This is what my storyboard looks like so far. On the left is my regular view controller, and on the right is the TableViewController. the transition inbetween has a specific ID.

**This is the first View Controller.**

class TestsMenuViewController: UIViewController {
var tests = [Test]() 
var testTableViewController : TestsTableViewController?


override func viewDidLoad() {
    self.tests = DataModel().patientData
    //this just populates the array with some data.
    super.viewDidLoad()
}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "testTableTransition" {
        testTableViewController = segue.destination as? TestsTableViewController
        testTableViewController?.tests = self.tests
        print(testTableViewController?.tests[0].testDescription)
        //somehow this is an empty array
    }
}

somehow the test array does not get passed to the next controller :( what am i doing wrong?

Answer 1

您可以将数据另存为NSUserDefaults，并在需要时调用保存的数据到视图

Answer 2

Hey I managed to solve my problem, what I just did was initialize the data that I pass to the TableViewController directly in the attributes. Then it worked!
