imagePickerController.sourceType = .photoLibrary

imagePickerController.delegate = self

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    if let mediaType = info[.mediaType] as? String, mediaType == kUTTypeImage as String {
        if let originalImage = info[.originalImage] as? UIImage {
            // 处理选择的图片
            let gifImageView = UIImageView(image: originalImage)
            // 在这里对gifImageView进行进一步处理或展示
        }
    }
    picker.dismiss(animated: true, completion: nil)
}
