如何导入一张图片并将其设置为 UIIMageView。然后再用另一个 UIIMageView？

Question

所以目前我已经设置好了，我可以在其中导入图像并将其设置为 UIImageView。我正在寻找的是有关如何再次执行此操作的帮助。我尝试了一些东西，但当我再次尝试时，却无法让任何东西真正起作用。我也会添加照片示例。

Photo Example

@IBAction func importImg(_ sender: Any) {
    //import image 1
    let picture = UIImagePickerController()
    picture.delegate = self
    picture.allowsEditing = false
    picture.sourceType = UIImagePickerControllerSourceType.photoLibrary
    self.present(picture, animated: false, completion: nil)
}

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

    if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {

        picture1.image = image
    }

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

Answer 1

你应该问你的第一个UIImageView是否为null，然后在那个里面加载图片，如果不是，在第二个UIImageView中加载图片。

if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {

    if picture1.image == nil {
        picture1.image = image
    }else {
        picture2.image = image
    }
}
