如何过滤 PhotoPicker 以仅显示图像，不显示视频和 GIF？

Question

使用

PhotoPicker

或

UIImage

时，我无法限制选择器仅显示图像，而不显示视频和 GIF。

struct ImagePickerView: UIViewControllerRepresentable {
    
    func makeUIViewController(context: Context) -> UIImagePickerController {
        let imagePicker = UIImagePickerController()
        imagePicker.delegate = context.coordinator
        
        // Filter to display only images (still includes GIFs)
        imagePicker.mediaTypes = [UTType.image.identifier]
        return imagePicker
    }
    
    func makeCoordinator() -> Coordinator {
        return Coordinator()
    }
    
    class Coordinator: NSObject, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
        
        func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
            if let selectedImageURL = info[.imageURL] as? URL {
                // Check if the selected file is a GIF
                if selectedImageURL.pathExtension.lowercased() == "gif" {
                    print("GIFs are not allowed.")
                    picker.dismiss(animated: true, completion: nil)
                    return
                }
            }
            
            if let selectedImage = info[.originalImage] as? UIImage {
                // Process the selected image
                print(selectedImage)
            }
            picker.dismiss(animated: true, completion: nil)
        }
    }
    
    func updateUIViewController(_ uiViewController: UIImagePickerController, context: Context) {
    }
}

我在 Swift 中使用

UIImagePickerController

来允许用户选择图像，但它仍然显示 GIF。我想完全排除 GIF 在选择器中显示。

我发现GIF在iOS上被归类为图像。

我认为使用选择器不可能做到这一点。

正如其他人在评论中建议的那样，您最好构建自己的照片选择器并使用 Apple 的 PhotoKit 框架获取照片。
