xcode - Swift 3 - 无法覆盖 'imagePickerController'

Question

我的代码:

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {
    self.image = image
    self.imageStatusLabel.text = "There is a picture"
    self.imageStatusLabel.textColor = UIColor.blue()

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

这是错误:

Cannot override 'imagePickerController' which has been marked unavailable: APIs deprecated as of iOS 7 and earlier are unavailable in Swift

好吧，我尝试使用更新的函数:

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    // But no image in the parameters
}

但是，参数中没有图像，我可以获取图像。
我该怎么办？

您必须使用 info 参数并强制转换为 UIImage .不要忘记你必须在 Privacy - Photo Library Usage Description 中输入“Privacy - Camera Usage Description”和“info.plist”文件并用字符串填充值，解释请求访问照片库和相机的原因。

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        pictureImageView.contentMode = .scaleToFill
        pictureImageView.image = pickedImage
    }

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