我想知道是否可以从 iOS 上的 mov 文件中提取如下元数据。

我通过在线提取器获得的元数据:

Answer 1

在你的didFinishPickingMediaWithInfo中

写，

   NSLog(@"meta data : %@",info);

您将在控制台中获得所有元数据的字典。

示例，

  - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {      

       NSLog(@"meta data : %@",info);

      // other code for picking media
   }
