Displaying input text on different views

Question

Was wondering if anybody could help on a simple problem

I have a UITextView on one page, where I want to enter text and store it in a string. Then when the next page is accessed, I would like that text to be displayed on that page, either in a new UITextView or some other way.

In my PostViewController.swift file (the first page) to get the input string, I have

@IBOutlet weak var postTextView: UITextView!

I tried making a new UITextView on the other view controller to try and display the string, and had the subsequent code, but can't figure it out from here.

@IBOutlet weak var copyText: UITextView!

let text: NSString = PostViewController().postTextView.text
???copyText = text??? (not sure if this is even close to right)

Any ideas would be appreciated and apologies for the noob question

Answer 1

In your PostViewController, implement prepareForSegue() to assign the value of its textfield to the variable in the second controller.

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

        if segue.identifier == "showSecondVC" { // Make sure the segue has this identity in Interface Builder

            let vc = segue.destinationViewController as! SecondVC // Change that to the actual class name

            vc.textFromVC1 = postTextView.text
        }
    }

In your second ViewController:

class SecondviewController: UIViewController {

    var textFromVC1: String!

    @IBOutlet weak var myTextField: UITextField!

    override func viewDidLoad() {
        myTextField.text = textFromVC1
    }
}
