iCloud & NSFileWrapper: Showing as 2 different files in Settings

I have an app that uses a UIDocument that is NSFileWrapper based. My file wrapper is a directory named "XXX.cp", with two sub-files "photo.data" and "photo.metadata". It seems to save and load documents fine, however when I go to Settings\Manage Storage\Unknown the sub-files are listed separately: I was expecting it to show "XXX.cp" instead of these two sub-files. I think I have the document UTI set up and exported properly: And I think I am creating the file wrappers correctly (especially since it reads/writes fine): ``` - (void)encodeObject:(id<NSCoding>)object toWrappers:(NSMutableDictionary *)wrappers preferredFilename:(NSString *)preferredFilename { @autoreleasepool { NSMutableData * data = [NSMutableData data]; NSKeyedArchiver * archiver = [[NSKeyedArchiver alloc] initForWritingWithMutableData:data]; [archiver encodeObject:object forKey:@"data"]; [archiver finishEncoding]; NSFileWrapper * wrapper = [[NSFileWrapper alloc] initRegularFileWithContents:data]; [wrappers setObject:wrapper forKey:preferredFilename]; } } - (id)contentsForType:(NSString *)typeName error:(NSError *__autoreleasing *)outError { if (self.captionedPhotoMetadata == nil || self.captionedPhoto == nil) { *outError = [[NSError alloc] initWithDomain:CaptionedPhotoErrorDomain code:CaptionedPhotoInvalidDocument userInfo:[NSDictionary dictionaryWithObjectsAndKeys:NSLocalizedString(@"Invalid document!", @""), NSLocalizedDescriptionKey, nil]]; return nil; } NSMutableDictionary * wrappers = [NSMutableDictionary dictionary]; [self encodeObject:self.captionedPhotoMetadata toWrappers:wrappers preferredFilename:METADATA_FILENAME]; [self encodeObject:self.captionedPhoto toWrappers:wrappers preferredFilename:DATA_FILENAME]; NSFileWrapper * fileWrapper = [[NSFileWrapper alloc] initDirectoryWithFileWrappers:wrappers]; return fileWrapper; } ``` But still no cigar. Anyone know what the problem is? Thanks!
