issue while populating String into textView - ios

Question

uploaded video (7 sec) for describing my problem
i have a textView embed in a tableView cell when we enter something on that textView the textview automatically increases its height according to entered content and also cell increases its size for doing this am using this approach:-
//tableViewCell
/// Custom setter so we can initialise the height of the text view
var textString: String {
get {
return textView?.text ?? ""
}
set {
if let textView = textView {
textView.text = newValue
textViewDidChange(textView)
}
}
}
override func awakeFromNib() {
super.awakeFromNib()
// Disable scrolling inside the text view so we enlarge to fitted size
textView?.scrollEnabled = false
textView?.delegate = self
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
if selected {
textView?.becomeFirstResponder()
} else {
textView?.resignFirstResponder()
}
}
}
extension MultiLineTextInputTableViewCell: UITextViewDelegate {
func textViewDidChange(textView: UITextView) {
let size = textView.bounds.size
let newSize = textView.sizeThatFits(CGSize(width: size.width, height: CGFloat.max))
// Resize the cell only when cell's size is changed
if size.height != newSize.height {
UIView.setAnimationsEnabled(false)
tableView?.beginUpdates()
tableView?.endUpdates()
UIView.setAnimationsEnabled(true)
if let thisIndexPath = tableView?.indexPathForCell(self) {
tableView?.scrollToRowAtIndexPath(thisIndexPath, atScrollPosition: .Bottom, animated: false)
}
}
}
here everything is fine but i added a function for Forwarding any content and for this am using this approach :-
forwardNoteAction = UITableViewRowAction(style: .Normal, title: "Forward"){ action, index in
let cell = tableView.cellForRowAtIndexPath(indexPath) as! NotesTableViewCell
if self.searchBar.text == "" {
let object: PFObject = self.noteObjects.objectAtIndex(indexPath.row) as! PFObject
let postsObjID = object.objectId!
let query = PFQuery(className: "Notes")
query.fromLocalDatastore()
query.getObjectInBackgroundWithId(postsObjID) {
(objectViewes, error) -> Void in
if error != nil {
print(error)
} else {
self.forwardObject = object
print(self.forwardObject)
//object.pinInBackground()
self.performSegueWithIdentifier("forwardNoteSegue", sender: nil)
self.tableView.deselectRowAtIndexPath(indexPath, animated: true)
}
i am putting the content into a variable self.forwardObject and passing that variable with an segue forwardNoteSegue after passing self.forwardObject am using that content for filling my tableView (which is a form , consist of textViews and TextFields) but when am doing this my textView is not increasing its height according to content which is inside that textView ,
all i want is the textView should increase increase its height when we use "textView.text = copiedContent" same as when we enter anything into the textView manually
please for understanding my problem properly see the uploaded video (link is provided above)
if my question is not understandable than please let me know i'll fix it
thanks

You need to manually call textViewDidChange when you modify the content of you textview programatically.
This is documented in the UITextviewDelegate's description of the method:
The text view calls this method in response to user-initiated changes to the text. This method is not called in response to
programmatically initiated changes.
