I have tableView within collectionView and i created using xib. I want to pushViewController when item is selected .I tried pushing the view controller in itemForRowAt method but it's not possible
class SecondTableView: UITableViewCell , UIcollectionViewDelegate ,UICollectionViewDataSource {
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
// let vc = DataTableViewController()
// vc.delegate = self
// vc.pushNav()
let memeVC = storyboard?.instantiateViewController(withIdentifier: "MemeViewController") as! MemeViewController
memeVC.imagePassed = image
navigationController?.pushViewController(memeVC, animated: true)
print("item tapped\(indexPath)")
}
}
errors Use of unresolved identifier 'storyboard'; did you mean 'UIStoryboard'?
Add segue as mentioned in the image and select show
Set segue identifier in your storyboard as mentioned in the image
Add below Protocol:
protocol CollectionViewCellDelegate: class {
func userDidTap()
}
Add below property in your table view class where the collection view delegate returns.
weak var delegate: CollectionViewCellDelegate?
Update delegate method
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
delegate.userDidTap()
print("item tapped\(indexPath)")
}
}
confirm CollectionViewCellDelegate delegate to your first view controller & add this method:
func userDidTap() {
performSegue(withIdentifier: "showMemeViewController", sender: nil)
}
Add prepare for segue in your first VC.
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "showMemeViewController" {
let memeVC: MemeViewController = segue.destination as! MemeViewController
memeVC.imagePassed = image
}
}
Please try this let me know if you faced any other issue. Thanks.
You're trying to access storyboard property in a tableview cell, which isn't there in the first place, it's a UIViewController property not a UITableViewCell property, hence the error, you'll have to delegate your selection to the viewController then let the controller do the segue normally.
You can start doing that via delegates as I mentioned above, for example if you're passing image to the controller you wanna segue to:
protocol ImageTableViewCellDelegate: class {
// pass the the image or any variable you want in the func params
func userDidTap(_ image: UIImage)
}
then you'd add it to the cell and confirm the controller to it
class SecondTableView {
weak var delegate: ImageTableViewCellDelegate?
}
In your controller:
extension MyViewController: ImageTableViewCellDelegate {
func userDidTap(_ image: UIImage){
let memeVC = storyboard?.instantiateViewController(withIdentifier: "MemeViewController") as! MemeViewController
memeVC.imagePassed = image
navigationController?.pushViewController(memeVC, animated: true)
print("item tapped\(indexPath)")
}
}
this should work, let me know if you had any further problems
