Hi all,
This is my code:
import UIKit
var imagePickerController:UIImagePickerController!
var secondViewController = SecondViewController()
@IBOutlet weak var camera1: UIButton!
@IBAction func takePhoto(_ sender: UIButton) {
// self.camera1.transform = CGAffineTransform(rotationAngle: CGFloat.pi)
if(UIImagePickerController.isSourceTypeAvailable(.camera))
{
self.imagePickerController = UIImagePickerController()
self.imagePickerController.delegate = self
self.imagePickerController.allowsEditing = true
self.imagePickerController.sourceType = UIImagePickerController.SourceType.camera
self.present(self.imagePickerController,animated: true,completion: nil)
}
}
override func viewDidLoad() {
super.viewDidLoad()
}
@objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
self.present(secondViewController,animated: true,completion: nil)
secondViewController.infoFromViewOne = info[UIImagePickerController.InfoKey.editedImage] as? UIImage
self.dismiss(animated: true, completion: nil)
}
@objc func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
self.dismiss(animated: true, completion: nil)
}
}
class SecondViewController: UIViewController {
var infoFromViewOne:UIImage?
@IBOutlet var image1: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
image1.image = infoFromViewOne
// Do any additional setup after loading the view.
}
}
I am trying to transmit a UIImage from another view when a button is clicked andI get an error saying: "fatal Error: Unexpectedly found nil while unwrapping an Optional value.
I really need help on this one as I have searched online for this topic and tried many things but nothing has worked. I would love to know if there is anything that can be done to solve this error or whether there is another war of changing a label from a different view.
All suggestions would be great!
Thanks
Thanks for confirmation. Considering the confirmed behavior this part may be causing the issue:
self.present(secondViewController,animated: true,completion: nil)
self.dismiss(animated: true, completion: nil)You present the secondViewController without dismissing the UIImagePickerController, and dismiss it immediately after that.
Which causes Nothing happens.
Please try replacing the two lines with the following:
self.dismiss(animated: true, completion: {
self.present(secondViewController,animated: true,completion: nil)
})With this change, the code first dismisses the UIImagePickerController, and after dismissing completed, the secondViewController will be presented.
