获取用于Unity的iOS图像的文件路径

我需要获取iOS图像的文件路径，以将其用于我在Unity中处理的项目。到目前为止，我有这样的代码：获取用于Unity的iOS图像的文件路径

#pragma mark - UIImagePickerControllerDelegate 
// This method is called when an image has been chosen from the library or taken from the camera. 
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *, id> *)info 
{ 
    NSString *type = [info objectForKey:UIImagePickerControllerMediaType]; 
    NSLog(@"type=%@",type); 
    if ([type isEqualToString:(NSString *)kUTTypeImage]) 
    { 
     NSURL* imageURL = (NSURL *)[info valueForKey:UIImagePickerControllerReferenceURL]; 
     NSString *urlString = [imageURL absoluteString]; 

     const char* cp = [urlString UTF8String]; 
     if(cp) 
      strcpy(image_path, cp); 
     else 
     {//If the image path is unasigned give ERROR instead 
      char* error = "ERROR"; 
      strcpy(image_path, error); 
     } 
    } 

    [self dismissViewControllerAnimated:YES completion:NULL]; 

    // UnitySendMessage("GameObject", "VideoPicked", video_url_path); 
    UnitySendMessage(callback_game_object_name, callback_function_name, image_path); 
}

然而，这返回一个格式的图像地址类似以下内容：

assets-library://asset/asset.JPG?id=92C96E1D-F714-49E6-8074-5B5980FF944F&ext=JPG

其中，据我可以告诉仅供iPhone库有用，有没有办法得到它的实际路径，还是完全走错了路线？

作为一个方面说明，Unity代码是完全正常的，可以得到统一接收字符串等，但它不知道如何处理它。

编辑：这个功能得到了它为我感谢来自PickerView工作潘卡他的回应

// This method is called when an image has been chosen from the library or taken from the camera. 
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *, id> *)info 
{ 
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectory = [paths objectAtIndex:0]; 
    NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:@"setName.png"]; 

    //save image here and then use that imagePath 
    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType]; 
    if ([mediaType isEqualToString:@"public.image"]){ 
     UIImage *editedImage = [info objectForKey:UIImagePickerControllerEditedImage]; 
     NSData *imageData = UIImagePNGRepresentation(editedImage); 
     [imageData writeToFile:imagePath atomically:YES]; 
    } 
    NSLog(@"imagePath=%@",imagePath); 
    const char* cp = [imagePath UTF8String]; 
    strcpy(image_path, cp); 

    [self dismissViewControllerAnimated:YES completion:NULL]; 

    UnitySendMessage(callback_game_object_name, callback_function_name, image_path); 
}

也许我不是专家，但在这里看不到任何C＃代码。 –

如果您从pickerView中获取图像，则可以将该图像存储在该目录中，然后可以将该目录路径用于Unity工作。 – Pankaj

获取图像，然后将其存储在文件目录，然后使用该路径的统一。

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:@"setName.png"]; 

//save image here and then use that imagePath 
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType]; 
if ([mediaType isEqualToString:@"public.image"]){ 
    UIImage *editedImage = [info objectForKey:UIImagePickerControllerEditedImage]; 
    NSData *imageData = UIImagePNGRepresentation(editedImage); 
    [imageData writeToFile:imagePath atomically:YES]; 
} 

UnitySendMessage(callback_game_object_name, callback_function_name, imagePath);
