Question

尝试允许用户从其照片库中选择照片，然后在UIImageView中显示该图像。照片库显示得很好，但是当我从我的库中选择一张照片时，我得到了这个错误＆＃34; [Generic]创建一个未知类型的图像格式是一个错误＆＃34;。

逐步完成下面的代码，但只有在选择这两个函数中没有出现的图像时才会出现错误。

@IBAction func openPhotoLibraryButton(sender: UIButton) {
    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.photoLibrary) {
        let imagePicker = UIImagePickerController()
        imagePicker.delegate = self
        imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary;
        imagePicker.allowsEditing = false
        self.present(imagePicker, animated: true, completion: nil)
    }
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {        
    let image = info[UIImagePickerControllerOriginalImage] as! UIImage!
    let imageData = UIImageJPEGRepresentation(image!, 0.6)
    let compressedJPGImage = UIImage(data: imageData!)
    imagePicked.image = compressedJPGImage
}

尝试了这里建议的解决方案：xCode 8 - Creating an image format with an unknown type is an error但它们都没有奏效，听起来有几个人没有解决这个问题。有任何想法吗？

您是否尝试在选择器之前添加_？我相信该方法已更改，您正在使用的方法已弃用，您应该可以让它自动完成。

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) { 
  if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
    if let imageData = UIImageJPEGRepresentation(image, 0.6) {
      let compressedJPGImage = UIImage(data: imageData)
      imagePicked.image = compressedJPGImage
    }
  } else {
    print("Image Picker Failure")
    //handle any possible image picker issues/failures so that app doesn't crash in the future
    //troubleshoot further if it always hits this
  }
  dismissViewControllerAnimated(true, completion: nil)
}

xcode 8.1＆amp; iOS 10.1.1＆＃34; [Generic]创建一个未知类型的图像格式是一个错误＆＃34;对于UIImagePickerController
