"Creating an image format with an unknown type is an error" with UIImagePickerController
提问by Jeet
While choosing an image from the image picker in iOS 10 Swift 3 I am getting an error - Creating an image format with an unknown type is an error
在 iOS 10 Swift 3 中从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)
}
The image is not getting selected and updated. I need help or suggestion to know if the syntax or anything regarding this method has been changed in iOS10 or Swift 3 or is there any other way to do this.
图像未被选中和更新。我需要帮助或建议来了解 iOS10 或 Swift 3 中有关此方法的语法或任何内容是否已更改，或者是否有任何其他方法可以执行此操作。

print("Something went wrong")
}
self.dismiss(animated: true, completion: nil)
}

Remember to add delegate to self
记得给自己添加委托
let picker = UIImagePickerController()
picker.delegate = self // delegate added

Below code did solve the problem:
下面的代码确实解决了问题：
If user perform changes to selected image pull only that image otherwise pull original image source without any changes and finally dismiss image picker view controller.
如果用户对所选图像执行更改，则仅拉取该图像，否则拉取原始图像源而不进行任何更改，最后关闭图像选择器视图控制器。
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)
}

If you allow editing of the picture imageController.allowsEditing = truethen you will need to get the edited image first:
如果您允许编辑图片，imageController.allowsEditing = true那么您需要先获取编辑后的图像：
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
}
}

The accepted solutionby Jeetendra Choudharyworks.Although in Xcode 8 with Swift 3 , I noticed that it generates a warning :
Instance method 'imagePickerController(_:didFinishPickingMediaWithInfo:)' nearly matches optional requirement 'imagePickerController(_:didFinishPickingMediaWithInfo:)' of protocol 'UIImagePickerControllerDelegate'
该接受的溶液通过杰滕德拉乔杜里works.Although在Xcode 8夫特3，我注意到，它生成一个警告：
Instance method 'imagePickerController(_:didFinishPickingMediaWithInfo:)' nearly matches optional requirement 'imagePickerController(_:didFinishPickingMediaWithInfo:)' of protocol 'UIImagePickerControllerDelegate'
and suggests to add either @nonobjcor privatekeyword to silence the warning.If you silence the warning using these suggestions , the solution no longer works though.
并建议添加@nonobjc或private关键字以消除警告。如果您使用这些建议消除警告，该解决方案将不再有效。

I found the default images in the photo library could couse this problem. If you drag an image from your computor onto the simulator and choose it. this problem is solved
我发现照片库中的默认图像可能会导致此问题。如果您将计算机中的图像拖到模拟器上并选择它。这个问题解决了
