iOS dropbox SDK loading thumbnails and number of files inside a folder -


hi developing application brings entire folder , file structure content management system have done box , sharepoint integration. looking sync dropbox now. in dbmetadata class have properties 

bool thumbnailexists; nsarray* contents; nsstring* icon;

  1. first thing want here want load thumbnails of files, not 1 thing icon property returns string, 'page_white_acrobat' (i thought return url or download thubmnail). there way bring thumbnails using dropbox sdk. uploaded .mp4 file , .png file, show thumbnails when open dropbox in chrome in sdk thumbnailexists property returns no.

  2. second want number of sub folders , files folder, tried accessing contents property of folder dbmetadata object , returned nil. there way in sdk count number of files inside folder or work around.

  1. it seems dropbox provides name of icon use. can't download it, should check string , use resources in app bundle.

  2. the contents of dbmetadata object null until make request load metadata @ path.

this code started subdirectories.

-(void)restclient:(dbrestclient *)client loadedmetadata:(dbmetadata *)metadata {     // load metadata of subdirectories     (dbmetadata *node in metadata.contents) {         if (node.isdirectory) {             [_restclient loadmetadata: node.path];         }     }      // count of directory contents     if (metadata.isdirectory) {         nslog(@"%@ contains %d files , folders", metadata.path, metadata.contents.count);     } }
