Swift3警告ImagePickerController几乎匹配

Question

在从旧版本的swift转换时，我会得到警告

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

警告是

实例方法 'imagePickerController（：didfinishpickingmediawithinfo :)'几乎 匹配可选要求 'ImagePickerController（：didfinishpickingmediawithinfo :)' uiimagePickerControllerDelegae

这里的问题在于，据我所知，它抱怨什么以及它所说的几乎是100％相同的。如何解决此警告？

Answer 1

在较新的Swift版本中，方法应为

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

然后，警告不会出现。

Answer 2

这是Swift 5.2

中的正确答案

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
     let tempImage = info[UIImagePickerController.InfoKey.originalImage] as! UIImage
     imgRoom.image  = tempImage
     self.dismiss(animated: true, completion: nil)
}
