Question

我正在用Xcode快速编写代码，并尝试创建一个具有两个UIImageViews的“编辑用户个人资料ViewController”，一个UIImageView用于个人资料照片，另一个用于封面照片。我很难更改封面照片的图像。当我进入模拟器并单击“更改封面照片”按钮并选择图像后，它将更改个人资料照片。当我单击更改个人资料照片按钮并选择图像时，它也会同时更改个人资料图像，但此操作是正确的。有谁知道如何帮助我在哪里可以更改这些控制器的图像，而不是让它们成为同一图像？这是我的下面的代码。

import UIKit

class profilephotoViewController: UIViewController {


    @IBOutlet weak var profileImagePhoto: UIImageView!

    @IBOutlet weak var profileImageTapped: UIButton!

    var imagePicker:UIImagePickerController!


    @IBOutlet weak var coverImagePhoto: UIImageView!

    @IBOutlet weak var coverImageTapped: UIButton!

    var secondImagePicker:UIImagePickerController!


    override func viewDidLoad() {
        super.viewDidLoad()

        let imageTap = UITapGestureRecognizer(target: self, action: #selector(openImagePicker))
        profileImagePhoto.isUserInteractionEnabled = true
        profileImagePhoto.addGestureRecognizer(imageTap)
        profileImagePhoto.layer.cornerRadius = profileImagePhoto.bounds.height / 2
        profileImagePhoto.clipsToBounds = true
        profileImageTapped.addTarget(self, action: #selector(openImagePicker), for: .touchUpInside)


        imagePicker = UIImagePickerController()
        imagePicker.allowsEditing = true
        imagePicker.sourceType = .photoLibrary
        imagePicker.delegate = self


        let coverTap = UITapGestureRecognizer(target: self, action: #selector(openSecondImagePicker))
        coverImagePhoto.isUserInteractionEnabled = true
        coverImagePhoto.addGestureRecognizer(coverTap)
        coverImagePhoto.clipsToBounds = true
        coverImageTapped.addTarget(self, action: #selector(openSecondImagePicker), for: .touchUpInside)

        secondImagePicker = UIImagePickerController()
        secondImagePicker.allowsEditing = true
        secondImagePicker.sourceType = .photoLibrary
        secondImagePicker.delegate = self

        // Do any additional setup after loading the view.
    }

    @objc func openImagePicker(_ sender:Any) {
        //Open Image Picker
        self.present(imagePicker, animated: true, completion: nil)
    }

    @objc func openSecondImagePicker(_ sender:Any) {
        //Open Second Image Picker
         self.present(secondImagePicker, animated: true, completion: nil)
    }
}

extension profilephotoViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        picker.dismiss(animated: true, completion: nil)
    }

    internal func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let pickedImage = info[UIImagePickerController.InfoKey.editedImage] as? UIImage {
            self.profileImagePhoto.image = pickedImage 
        }
        picker.dismiss(animated: true, completion: nil)
    }

    func secondImagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        picker.dismiss(animated: true, completion: nil)
    }

    internal func secondImagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let secondPickedImage = info[UIImagePickerController.InfoKey.editedImage] as? UIImage {
            self.coverImagePhoto.image = secondPickedImage   
        }
        picker.dismiss(animated: true, completion: nil)
    }
}

您可以尝试

internal func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {

       if let secondPickedImage = info[UIImagePickerController.InfoKey.editedImage] as? UIImage {

          if let picker == imagePicker  {
              self.profileImagePhoto.image = secondPickedImage
          }
          else {
              self.coverImagePhoto.image = secondPickedImage   
          } 

       }

       picker.dismiss(animated: true, completion: nil)
}
