If you want to allow any file type, you should use

UIDocumentPickerViewController* documentPicker = 
  [[UIDocumentPickerViewController alloc] initWithDocumentTypes:@[@"public.data"]
                                                         inMode:UIDocumentPickerModeImport];

See apple docs for UTI concepts
