Question

我有2 UIImageViews和2个按钮的视图，以便用UIImagePickerViewController选择2张不同的照片。它实际上是完美的，但我想缩放图像，最后在UIImageViews中显示图像的选定部分。

允许编辑在缩放时正常工作，显然“允许编辑”图片，但最终选定的部分不会出现在UIImageViews中。

代码就在这里。有什么问题？

import UIKit

var fotoUnoEscogida = UIImage()
var fotoDosEscogida = UIImage()


class viewControllerDso : UIViewController, UIImagePickerControllerDelegate ,UINavigationControllerDelegate, UITextViewDelegate{


    //Images
    @IBOutlet weak var imageView1: UIImageView!
    @IBOutlet weak var imageView2: UIImageView!
    //TextViews
    @IBOutlet weak var textViewExteriorUno: UITextView!
    @IBOutlet weak var textViewExteriorDos: UITextView!
    @IBOutlet weak var textViewInteriorUno: UITextView!
    @IBOutlet weak var textViewInteriorDos: UITextView!




    var imagePicker = UIImagePickerController()
    var imagePicked = 0

    override func viewDidLoad() {
        super.viewDidLoad()



    }


    @IBAction func chooseImage(sender: UIButton) {
        if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.SavedPhotosAlbum){
            print("chooseImage Button capture ")

            imagePicked = sender.tag
            imagePicker.delegate = self
            imagePicker.sourceType = .SavedPhotosAlbum
            imagePicker.allowsEditing = true

            self.presentViewController(imagePicker, animated: true, completion: nil)
        }
    }
    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
        let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage

        if imagePicked == 1 {

            imageView1.contentMode = UIViewContentMode.ScaleAspectFill
            imageView1.image = pickedImage

            imageView1.layer.masksToBounds = true
            imageView1.layer.borderWidth = 6
            imageView1.layer.cornerRadius = imageView1.layer.frame.height/6
            imageView1.layer.borderColor = UIColor.purpleColor().colorWithAlphaComponent(0.2).CGColor




        } else if imagePicked == 2 {


            imageView2.contentMode = UIViewContentMode.ScaleAspectFill
            imageView2.image = pickedImage

            imageView2.layer.masksToBounds = true
            imageView2.layer.borderWidth = 6
            imageView2.layer.cornerRadius = imageView2.layer.frame.height/6
            imageView2.layer.borderColor = UIColor.purpleColor().colorWithAlphaComponent(0.2).CGColor




        }
        dismissViewControllerAnimated(true, completion: nil)
    }


}

Answer 1

didFinishPickingMediaWithInfo中的

而不是

let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage

使用

let pickedImage = info[UIImagePickerControllerEditedImage] as? UIImage

Answer 2

更新Swift 5.2

RUN C:\TEMP\vs_buildtools.exe --quiet --wait --norestart --nocache `
    --installPath C:\BuildTools `
    --add Microsoft.VisualStudio.Workload.AzureBuildTools `
    # <append the line below>
