Question

所以我在显示YPImagePicker中的selectedImage时遇到问题，我通常不喜欢使用第三方资源，但是图像选择器正是我想要的。无论如何，所选图像不会显示在下一个视图控制器中。我觉得我的代码是正确的，但显然我猜不是。也没有错误。

* **由于下面的配合，将下面的代码编辑为工作代码。

// First VC to open imagePicker
  @IBAction func cameraButtonTapped(_ sender: Any) {

        let picker = YPImagePicker()
        picker.didFinishPicking { [unowned picker] items, cancelled in

            if let photo = items.singlePhoto {
                let shareVC =    self.storyboard?.instantiateViewController(withIdentifier:   "SharePhotoController") as! SharePhotoViewController
                shareVC.selectedImage = photo.modifiedImage ?? photo.image
               picker.pushViewController(shareVC, animated: true)


            }
        present(picker, animated: false, completion: nil)

//应该显示所选图像的第二个VC的代码

 @IBOutlet weak var finalPhoto: UIImageView!

    @IBOutlet weak var addCaptionTextField: UITextField!

    var selectedImage: UIImage?


    override func viewDidLoad() {
        super.viewDidLoad()

   self.finalPhoto.image = selectedImage

Answer 1

您将照片分配给您不存在的vc（即sharePostVC）

picker.dismiss(animated: true) {
   if let photo = items.singlePhoto {  
     let shareVC = self.storyboard?.instantiateViewController(withIdentifier: "SharePhotoController") as! SharePhotoViewController
      shareVC.selectedImage = photo.modifiedImage ?? photo.image
      self.picker.pushViewController(shareV, animated: true) 
   }
}

为避免崩溃，请同时移除didSet部分并将图像分配到viewDidLoad的{{1}}内的图像视图中

无法从YPImagePicker显示所选图像
