Question

从iOS 10 Swift 3中的图像选择器中选择图像时出现错误 - Creating an image format with an unknown type is an error

 func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {

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

未选择并更新图像。我需要帮助或建议才能知道在iOS10或Swift 3中是否更改了此方法的语法或任何内容，或者是否有其他方法可以执行此操作。

Answer 1

下面提到的代码确实解决了我的问题 -

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
        imagePost.image = image
    } else{
        print("Something went wrong")
    }

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

Answer 2

请记住将委托添加到自己

let picker = UIImagePickerController()
picker.delegate = self // delegate added

Answer 3

下面的代码确实解决了问题：

如果用户对所选图像执行更改，则仅拉动该图像，否则无需任何更改即可拉动原始图像源，最后取消图像选取器视图控制器。

public func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]){
    if let image = info[UIImagePickerControllerEditedImage] as? UIImage {
        imageView.image = image
    }
    else if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
        imageView.image = image
    } else{
        print("Something went wrong")
    }

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

Answer 4

如果您允许编辑图片imageController.allowsEditing = true，则需要先获取已编辑的图片：

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    picker.dismissViewControllerAnimated(true, completion: nil)

    if let image = info[UIImagePickerControllerEditedImage] as? UIImage {
        imagePost.image = image
    } else if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
        imagePost.image = image
    } else {
        imagePost.image = nil
    }
}

Answer 5

accepted solution Jeetendra Choudhary有效。虽然在Xcode 8中使用Swift 3，我注意到它会生成警告： Instance method 'imagePickerController(_:didFinishPickingMediaWithInfo:)' nearly matches optional requirement 'imagePickerController(_:didFinishPickingMediaWithInfo:)' of protocol 'UIImagePickerControllerDelegate'

并建议添加 @nonobjc 或私有关键字以消除警告。如果您使用这些建议使警告静音，则解决方案不再有效。

Answer 6

我发现照片库中的默认图像可以解决这个问题。如果将图像从计算机拖动到模拟器上并选择它。这个问题解决了

Answer 7

根据Abdurohman的回答，我改变了我的代码并解决了问题，谢谢。

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImage

    photoImageView.image = selectedImage

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

Answer 8

将此添加到viewDidload（）

imagepicker.delegate = self

Answer 9

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
        imgViewPhoto.image = image
    } else{
        print("Something went wrong")
    }

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

}

Answer 10

我认为你错过了photoImageView和图片之间的联系。

看看下面的截图：

Answer 11

对于带有swift 3的Xcode 8.1，在更改委托方法后如下

改变你的

func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {

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

功能

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

    {


imagePost.image = info[UIImagePickerControllerOriginalImage] as? UIImage
 picker.dismiss(animated: true, completion: nil)

}

我忘了将UINavigationControllerDelegate和UIImagePickerControllerDelegate一起添加到

中

class ViewController:UIViewController,UIImagePickerControllerDelegate,UINavigationControllerDelegate

你会在开头添加一个变量，如

var imagePicker = UIImagePickerController（）

并设置委托并将viewdidload（）中的函数调用为

 imagePicker.delegate = self
 viwImagePick()

然后将该功能解释为

  //ImagePicker
    func viwImagePick(){


        let alert = UIAlertController(title: nil, message: "Choose your source", preferredStyle: UIAlertControllerStyle.alert)

        alert.addAction(UIAlertAction(title: "Camera", style: UIAlertActionStyle.default) { (result : UIAlertAction) -> Void in
            print("Camera selected")
            self.openCamera()

            //Code for Camera
            //cameraf
        })
        alert.addAction(UIAlertAction(title: "Photo library", style: UIAlertActionStyle.default) { (result : UIAlertAction) -> Void in
            print("Photo selected")
            self.openGallary()

            //Code for Photo library
            //photolibaryss
        })


        self.present(alert, animated: true, completion: nil)
           }



    func openCamera()
    {
        imagePicker.sourceType = UIImagePickerControllerSourceType.camera
        if UIDevice.current.userInterfaceIdiom == .phone
        {
            self.present(imagePicker, animated: true, completion: nil)
        }
        else
        {
            let popover = UIPopoverController(contentViewController: imagePicker)

            popover.present(from: profileImgViw.frame, in: self.view, permittedArrowDirections: UIPopoverArrowDirection.any, animated: true)

        }
    }

    func openGallary()
    {
        imagePicker.sourceType = UIImagePickerControllerSourceType.savedPhotosAlbum
        if UIDevice.current.userInterfaceIdiom == .phone
        {
            self.present(imagePicker, animated: true, completion: nil)
        }
        else
        {
           let popover = UIPopoverController(contentViewController: imagePicker)

            popover.present(from: profileImgViw.frame, in: self.view, permittedArrowDirections: UIPopoverArrowDirection.any, animated: true)


        }
    }

现在图像已添加到库中的图像视图

Answer 15

如果这对任何人都有帮助，那么当我将UIImageView子类化以创建圆角视图时，我就会发生这种情况。当我在viewDidLoad（）

中添加以下行时也会发生这种情况

imageView.layer.cornerRadius = self.imageView.frame.size.width / 2

我最终在viewWillLayoutSubViews中添加了这行，并且它有效。有关详细信息，请参阅此处：

clipsToBounds causes UIImage to not display in iOS10 & XCode 8

Answer 16

这对我有用：

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
        imageView.image = image
        self.dismiss(animated: true, completion: nil)
    }
}

Answer 17

在函数参数中添加“_”。

这

func imagePickerController(picker: UIImagePickerController ...

到

func imagePickerController(_ picker: UIImagePickerController ...

//带有集合视图的图像选择器 class ViewController：UIViewController，UIImagePickerControllerDelegate，UINavigationControllerDelegate，UICollectionViewDataSource，UICollectionViewDelegate {

@IBAction func btnselect(_ sender: UIButton) {


    imgpkr.allowsEditing = true // false
    imgpkr.sourceType = .photoLibrary
    imgpkr.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!
    present(imgpkr, animated: true, completion: nil)

    image.add(edit)
    collview.reloadData()

    dismiss(animated: true, completion: nil)

    cell.img1.image = image.object(at: indexPath.item)as! UIImage

    return cell



}

Answer 19

尝试以下

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    print("image selected");
    let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImag
    self.dismiss(animated: true, completion: nil)
   UIImg.image = selectedImage
}

Answer 20

我做的是，一旦我从didFinishPickingMediaWithInfo获得图像，我就打电话给：

func prepareImageForSaving(image:UIImage) {
    // create NSData from UIImage
    guard let imageData = UIImageJPEGRepresentation(image, 1) else {
        // handle failed conversion
        print("jpg error")
        return
    }

    self.saveImage(imageData: imageData as NSData)
}

func saveImage(imageData: NSData) {
    imageDatas = imageData
}

以NSData格式保存。

控制台仍警告我＆＃34; [Generic]创建一个未知类型的图像格式是一个错误＆＃34;但至少我的imageView会更新到所选图像，而不是从viewDidLoad显示前一个图像。

Answer 21

这对我有用。只需复制并粘贴即可。

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    // The info dictionary contains multiple representations of the image, and this uses the original.
        let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImage

    // Set photoImageView to display the selected image.
     photoImageView.image = selectedImage

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

Answer 22

请务必同时包含UINavigationControllerDelegate代表。这解决了我的问题。

Answer 23

对我来说，我遇到了错误：

“致命错误：意外发现零...”

在图像选择器中选择图像时。

为解决该问题，我再次创建了imageView的插座。

＆＃34;创建具有未知类型的图像格式是错误＆＃34;使用UIImagePickerController
