Swift 4.2 imagePickerController问题

UIImagePickerControllerEditedImage //无法使用索引类型为“UIImagePickerController.InfoKey”的类型'[String：Any]’下标

func imagePickerController(_ picker: UIImagePickerController,dIDFinishPickingMediawithInfo info: [String : Any]) {    if let pickedImage = info[UIImagePickerControllerEditedImage] as? UIImage {        self.userProfileImage.contentMode = .scaleAspectFit        self.userProfileImage.image = pickedImage    }    picker.dismiss(animated: true,completion: nil)}

解决方法 方法签名已更改为

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

您应该看到func名称的警告消息

Instance method
‘imagePickerController(:dIDFinishPickingMediawithInfo:)’ nearly
matches optional requirement
‘imagePickerController(:dIDFinishPickingMediawithInfo:)’ of protocol
‘UIImagePickerControllerDelegate’

CandIDate has non-matching type ‘(UIImagePickerController,[String :
Any]) -> ()’

Move ‘imagePickerController(_:dIDFinishPickingMediawithInfo:)’ to
another extension to silence this warning

Make ‘imagePickerController(_:dIDFinishPickingMediawithInfo:)’ private
to silence this warning

Requirement ‘imagePickerController(_:dIDFinishPickingMediawithInfo:)’ declared here (UIKit.UIImagePickerControllerDelegate)
