I have a UItableView and I perform a segue to a UIView. The information varies on the presented UIView depending on what row is selected in the UITableView. The UIView gets presented perfectly.
The problem is that when the new UIView is presented, if I click in the same place on the screen where the initial row was, I then segue back to the UITableView.
I made a segue on the storyboard called dayx.
I then used the following code to present the new UIView.
Here is the code I used to perform the segue:
//when row is pressed what happens
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let destinationVC = segue.destination as! foodinfo
destinationVC.counter = rowselected
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
rowselected = indexPath.row
self.performSegue(withIdentifier: "dayx", sender: self)
//making desleected row not highlighted
tableView.deselectRow(at: indexPath, animated: true)
}
the presented UIView code is as follows:
class foodinfo: UIViewController {
var counter = Int()
let playerController = AVPlayerViewController()
@IBOutlet var tabs: UISegmentedControl!
@IBOutlet var theTitleLable: UILabel!
@IBOutlet var stack: UIStackView!
@IBOutlet var ScrollView: UIScrollView!
@IBOutlet var foodImageview: UIImageView!
@IBOutlet var navBar: UINavigationBar!
var simpleViewX: UIView!
var simpleViewY: UIView!
var theTitleArray = ["title1","title2","title3","title4","title5","title6","title7"]
var theImageArray = ["image1", "image2", "image3","image4","image5",image6","image7"]
//video links
var calledVideo: String?
let vids = ["https://vimeo.com/123456789","https://vimeo.com/123456789", "https://vimeo.com/123456789", "https://vimeo.com/123456789","https://vimeo.com/123456789","https://vimeo.com/123456789","https://vimeo.com/123456789"]
override func viewDidLoad() {
NotificationCenter.default.addObserver(self, selector: #selector(self.deviceOrientationDidChange), name: UIDevice.orientationDidChangeNotification, object: nil)
getTitle()
getImage()
getNavbar()
//Different subViews for ingredients and steps
if counter == 0 {
simpleViewX = SimpleVC0().view
simpleViewY = SimpleVC1().view
stack.addArrangedSubview(simpleViewX)
stack.addArrangedSubview(simpleViewY)
simpleViewY.isHidden = true
}

I have no idea why it segues back to the UITableView. Anyone know what im doing wrong?
You mention that you're using a Storyboard and that you've connected your two views UITableView and destination UIView with a segue with identifier "dayx".
Is there some specific reason you're overriding tableView(didSelectRowAt:)?
Have you considered or attempted to use code similar to this (and removing tableView(didSelectRowAt:))...?
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier = "dayx" {
if let rowSelected = tableView.indexPathForSelectedRow {
let destinationVC = segue.destination as! foodinfo
destinationVC.counter = rowSelected
}
}
}
Also set the following default property (in viewWillAppear(animated))to suit your UI...
clearsSelectionOnViewWillAppear = true (or false).
