Я хочу привязать свой ImageView к viewModel для сохранения выбранного изображения в Core Data.
Мой код выглядит следующим образом:
class FoodViewModel: FoodViewModelType {
var foodImage: BehaviorRelay<UIImage?>
//... another code
}
Мой контроллер:
class NewFoodViewController: UIViewController {
@IBOutlet weak var foodImageView: UIImageView!
override func viewDidLoad() {
//... another code
self.foodImageView.rx.image.bind(to: foodViewModel.foodImage).disposed(by: self.disposeBag)
}
}
И я получаю ошибку:
Значение типа Binder не имеет члена 'bind'
Как сохранить мой образ в Core Data с хорошей практикой MVVM?

Явыберите фотографию в контроллере вида:
func chooseImagePickerAction(source: UIImagePickerController.SourceType) {
if UIImagePickerController.isSourceTypeAvailable(source) {
let imagePicker = UIImagePickerController()
imagePicker.sourceType = source
imagePicker.delegate = self
self.present(imagePicker, animated: true, completion: nil)
}
}
@objc func foodImageViewTapped(_ sender: AnyObject) {
let alertController = UIAlertController(title: "Photo path", message: nil, preferredStyle: .actionSheet)
let cameraAction = UIAlertAction(title: "Camera", style: .default) { (action) in
self.chooseImagePickerAction(source: .camera)
}
let photoLibAction = UIAlertAction(title: "Photo", style: .default) { (action) in
self.chooseImagePickerAction(source: .photoLibrary)
}
let cancelAction = UIAlertAction(title: "Cancel", style: .default)
alertController.addAction(cameraAction)
alertController.addAction(photoLibAction)
alertController.addAction(cancelAction)
self.present(alertController, animated: true, completion: nil)
}
extension NewFoodViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
let info = convertFromUIImagePickerControllerInfoKeyDictionary(info)
foodImageView.image = info[convertFromUIImagePickerControllerInfoKey(UIImagePickerController.InfoKey.originalImage)] as? UIImage
foodImageView.contentMode = .scaleAspectFill
dismiss(animated: true, completion: nil)
}
private func convertFromUIImagePickerControllerInfoKeyDictionary(_ input: [UIImagePickerController.InfoKey: Any]) -> [String: Any] {
return Dictionary(uniqueKeysWithValues: input.map {key, value in (key.rawValue, value)})
}
private func convertFromUIImagePickerControllerInfoKey(_ input: UIImagePickerController.InfoKey) -> String {
return input.rawValue
}
}
и в viewDidLoad (без изображения):
saveNewFoodBarButtonItem.rx.tap.subscribe(onNext: { [weak self] _ in
guard let self = self else { return }
let foodViewModel = FoodViewModel()
self.foodQuantityTypeTextField.rx.text.bind(to: foodViewModel.foodQuantityType).disposed(by: self.disposeBag)
self.foodShelfLifeTextField.rx.text.bind(to: foodViewModel.foodShelfLife).disposed(by: self.disposeBag)
self.foodCategoryTextField.rx.text.bind(to: foodViewModel.foodCategoryId).disposed(by: self.disposeBag)
self.foodQuantityTextField.rx.text.bind(to: foodViewModel.foodQuantity).disposed(by: self.disposeBag)
self.foodNameTextField.rx.text.bind(to: foodViewModel.foodName).disposed(by: self.disposeBag)
foodViewModel.saveNewFood(fridgeViewModel: self.fridgeViewModel!)
self.dismiss(animated: true)
}).disposed(by: disposeBag)
