How to push a navigation view using collectionView didSelectItemAt? - ios

Question

I am writing a code for my school project. As a beginner would, I looked up on tutorials on youtube how to code.
To summarize the hierarchy of my used objects:
Main collectionView (first one loaded) for scrolling horizontally between views.
List collectionView for listing cells.
collectionViewCell cells for listing information.
However, I am unable to find a way so that when I call a didSelectItemAt function by tapping on one of the cells to push a new view. I have tried creating a function that pushes the view in the MainViewController and call it by creating an instance of the class in didSelectItemAt function but I had no luck.

Answer 1

have you added datasource and delegate?. if you added please check cell click working or not. if click is working add bellow navigation code.
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
let controller = self.storyboard?.instantiateViewController(withIdentifier: "SecondViewController") as! SecondViewController
self.navigationController?.pushViewController(controller, animated: true)
}

Contributing to Raj's answer, if you want to push a view controller when selecting some specific item in your collection view, just a slight variation of condition will do the trick, this delegate method is called with you click on an item in your collection view:
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
if indexPath.item == **<your item's index>** {
let controller = self.storyboard?.instantiateViewController(withIdentifier: "SecondViewController") as! SecondViewController
self.navigationController?.pushViewController(controller, animated: true)
}
}

Add the upper Side the Class like this :
class tableViewVC : UIViewController, UITableViewDelegate, UITableViewDataSource {
}
Add inside ViewDidLoad():
tableView.delegate = self
tableView.datasource = self
And then you will use in TableView Method like this :
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let ViewController = UIStoryboard.init(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "SecondViewController") as? SecondViewController
self.navigationController?.pushViewController(ViewController!, animated: true)
}
