Я хочу получить оператор if, который, если выбранная кнопка соответствует первому виду изображения, устанавливает его на первое изображение, иначе устанавливает его на второй вид изображения ... Но, как только я выбираю изображение из image picker, он просто игнорирует его и движется, как будто ничего не случилось.
Вот мой код:
(это вниз под контроллером выбора изображений func ...)
class UploadSubPostCell: UICollectionViewCell {
@IBOutlet weak var previewStep: UIImageView!
}
class UploadViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
@IBOutlet weak var previewImage: UIImageView!
@IBOutlet weak var postBtn: UIButton!
@IBOutlet weak var selectBtn: UIButton!
@IBOutlet weak var postscollectionview: UICollectionView!
@IBOutlet weak var selectStepsBtn: UIButton!
var picker = UIImagePickerController()
var isThumbnailImage = true
var subpostsArray = [UIImage]()
var subposts = [SubPost]()
var posts = [Post]()
override func viewDidLoad() {
super.viewDidLoad()
setupNavigationBarItems()
picker.delegate = self
}
func setupNavigationBarItems() {
navigationItem.title = "Upload"
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let image = info[UIImagePickerControllerEditedImage] as? UIImage {
let path = IndexPath(item: 0, section: 0)
let cell = self.postscollectionview.cellForItem(at: path) as? UploadSubPostCell
if isThumbnailImage{
previewImage.image = image
} else {
cell?.previewStep.image = image
}
selectBtn.isHidden = false
selectStepsBtn.isHidden = false
postBtn.isHidden = false
if isThumbnailImage == false {
subpostsArray.append(image)
subposts.count + 1
print("Appended image to array:", subpostsArray)
}
}
picker.dismiss(animated: true, completion: nil)
}
@IBAction func selectStepPressed(_ sender: Any) {
picker.allowsEditing = true
picker.sourceType = .photoLibrary
isThumbnailImage = false
self.present(picker, animated: true, completion: nil)
}
@IBAction func selectPressed(_ sender: Any) {
picker.allowsEditing = true
picker.sourceType = .photoLibrary
isThumbnailImage = true
self.present(picker, animated: true, completion: nil)
}
@IBAction func addNewPressed(_ sender: Any) {
}
@IBAction func postPressed(_ sender: Any) {
AppDelegate.instance().showActivityIndicator()
let uid = Auth.auth().currentUser!.uid
let ref = Database.database().reference()
let storage = Storage.storage().reference(forURL: "gs://mobile-d9fcd.appspot.com")
let key = ref.child("posts").childByAutoId().key
let imageRef = storage.child("posts").child(uid).child("\(key).jpg")
let data = UIImageJPEGRepresentation(self.previewImage.image!, 0.6)
let uploadTask = imageRef.putData(data!, metadata: nil) { (metadata, error) in

let postFeed = ["\(key)" : feed]
ref.child("posts").updateChildValues(postFeed)
AppDelegate.instance().dismissActivityIndicator()
self.picker.dismiss(animated: true, completion: nil)
}
})
}
uploadTask.resume()
}
