Swift / XCode-使用ImagePickerController選擇另一個

Question

我想知道如何使用ImagePickerController選擇多個圖像。

但是，我不希望在ImagePickerController控制器中選擇多個圖像。 相反，當用戶選擇我的應用程序設置imageView （他們都有一個tapGestureRecogniser ）。 有10個。因此，每當用戶點擊某個imageView ，我都希望將圖像應用於所選的imageView 。

但是，它始終覆蓋第一個imageView 。

我該如何解決？

因此，想象一下這些是我的imageViews：

[1] [2] [3] [4] [5]

我點擊第三個，然后選擇一張圖像。 然后應將圖像應用於第三個imageView。 然后，我可以決定選擇第一個imageView並添加另一個圖像等。

我希望這是有道理的。

編輯x 2-我的代碼：

            let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.handleSelectedImage))
            selectedImage.addGestureRecognizer(tapGesture)
            selectedImage.isUserInteractionEnabled = true
     func handleSelectedImage() {

            let pickerController = UIImagePickerController()
            pickerController.delegate = self
            pickerController.mediaTypes = ["public.image", "public.movie"]
            pickerController.allowsEditing = true
            pickerController.modalPresentationStyle = .popover
            pickerController.popoverPresentationController?.delegate = self as! UIPopoverPresentationControllerDelegate
            pickerController.popoverPresentationController?.sourceView = selectedImage
            let alertController = UIAlertController(title: "Add a Picture", message: "Choose From", preferredStyle: .actionSheet)

            let cameraAction = UIAlertAction(title: "Camera", style: .default) { (action) in
                pickerController.sourceType = .camera
                self.present(pickerController, animated: true, completion: nil)

            }
            let photosLibraryAction = UIAlertAction(title: "Photos Library", style: .default) { (action) in
                pickerController.sourceType = .photoLibrary
                self.present(pickerController, animated: true, completion: nil)

            }

            let savedPhotosAction = UIAlertAction(title: "Saved Photos Album", style: .default) { (action) in
                pickerController.sourceType = .savedPhotosAlbum
                self.present(pickerController, animated: true, completion: nil)

            }

            let videoAction = UIAlertAction(title: "Videos", style: .default) { (action) in

                pickerController.mediaTypes = ["public.movie"]
                pickerController.sourceType = .photoLibrary
                self.present(pickerController, animated: true, completion: nil)

            }

            let cancelAction = UIAlertAction(title: "Cancel", style: .destructive, handler: nil)

            alertController.addAction(cameraAction)
            alertController.addAction(photosLibraryAction)
            alertController.addAction(savedPhotosAction)
             alertController.addAction(videoAction)
            alertController.addAction(cancelAction)



            present(alertController, animated: true, completion: nil)

        }

        func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
            return .none

        }


extension AddPostViewController: UINavigationControllerDelegate, UIImagePickerControllerDelegate, UIPopoverPresentationControllerDelegate {

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

        if let image = info["UIImagePickerControllerOriginalImage"] as? UIImage {
            chosenImage = image
            selectedImage.image = image
            dismiss(animated: true, completion: {
                self.performSegue(withIdentifier: "returnHome", sender: nil)
            })
        }



    }

Answer 1

您可以做的是使用imageView的tag屬性以及一個變量來記錄哪個imageView進行了調用。 下面提到的是一個粗略的輪廓。

• 創建一個變量（比如selectedImageView ）
• 從1-5設置imageViews的tag屬性
• 當一個imageView進行調用打開imagePickerController ，設置selectedImageView = imageView.tag
• 拾取圖像后，檢查selectedImageView的值並將該圖像設置為具有相同標簽的imageView
