Question

I have a remote directory with several subdirectories and files in them on Dropbox.

remote side:

-Mobile Profiles *(root)*
-- Custom Profiles
--- Profile1
--- Profile2
--- Profile3

Uploading the files and directories / and subdirectories with files is not a problem. I am having a brain fart when it comes to getting the subdirectories and their contents from dropbox to the device.

put

-(void)backupCustomProfiles {
    for ( NSString *file in [[NSFileManager defaultManager] contentsOfDirectoryAtPath:MP_CUSTOM error:&error] ) {
        [self.restClient uploadFile:file toPath:@"/Mobile Profiles/Custom Profiles/" fromPath:EasyStrings(MP_CUSTOM,file)];
    }
}

get

-(void)restoreCustomProfiles {
    for ( ) {
        /* ? */
    }
}

I am not sure how to iterate through the subdirectories on the remote side.

First load the directory metadata, then load the files that it references.

To limit the number of parallel fetches, use a NSOperationQueue for all of the loadMetadata and loadFile calls to limit the number of parallel fetches. And to avoid redundant file downloads, remember the downloaded metadata in a plist.

- (void) restoreCustomProfiles
{
    [self.client loadMetadata:@"/Mobile Profiles/Custom Profiles" withHash:hash];
}

- (void) restClient:(DBRestClient*)client loadedMetadata:(DBMetadata*)metadata
{
    for (DBMetadata* child in metadata.contents) {
        NSString *path = [child.path lowercaseString];

        if (child.isDirectory) {
            [client loadMetadata:child.path withHash:hash];
        } else {
            [client loadFile:pathToDownload intoPath:[
                                self.directory stringByAppendingString:path]];
        }
    }
}

- (void) restClient:(DBRestClient*)client loadedFile:(NSString*)destPath
{
    // successfully downloaded a file to destPath
}
