Get Audio Files From Dropbox iOS Core API -

-

i need list audio files user's dropbox. configured app on developer console have corresponding permissions. authenticated user, can retrieve directories want method goes every folder , list audiofiles can find. method have 3 concerns.

  1. the method kind of slow (recursive)

  2. i getting 2 random errors (probably due multiple request per second)

    listing random folder.

    2015-06-02 12:44:52.634 podbox[9038:2918749] error loading metadata: error       domain=dropbox.com code=503 "the operation couldn’t completed.  (dropbox.com error 503.)" userinfo=0x170270780 {path=/ios  dev/passbook/signpass/signpass.xcodeproj/xcuserdata/gsteele.xcuserdatad,  error=rate limiting oauth_accesses_per_access_token}

    accessing music

    2015-06-02 12:44:32.665 podbox[9038:2918749] error loading metadata: error  domain=nsurlerrordomain code=-1001 "the operation couldn’t completed. (nsurlerrordomain error -1001.)"  userinfo=0x17047cf00 {path=/music/blink 182/unknown album}

  3. i know im getting mp3 files. there way media files without checking pathextensions?

currently trying this:

- (void)restclient:(dbrestclient *)client loadedmetadata:(dbmetadata *)metadata {    if (metadata.isdirectory) {      (dbmetadata *file in metadata.contents) {              if (file.isdirectory) {                  [self.restclient loadmetadata:file.path];              } else if ([file.path.pathextension isequaltostring:@"mp3"]){                  nslog(@"    %@", file.filename);              }          }     } }

you awesome.

the metadata method inefficient when used recursively this, instead, you'll want use loaddelta method:

/* loads list of files (represented dbdeltaentry objects) have changed since cursor generated */ - (void)loaddelta:(nsstring *)cursor;  - (void)restclient:(dbrestclient*)client loadeddeltaentries:(nsarray *)entries reset:(bool)shouldreset cursor:(nsstring *)cursor hasmore:(bool)hasmore; - (void)restclient:(dbrestclient*)client loaddeltafailedwitherror:(nserror *)error;

there's blog post here (albeit python) covers basic idea of how use this:

https://blogs.dropbox.com/developers/2013/12/efficiently-enumerating-dropbox-with-delta/

this should more efficient method in case, resolving first 2 issues.

it doesn't offer way filter specific file types on server though, you'll need client-side.

i have following code almost works properly; private void cbstatus_drawitem(object sender, listboxdrawitemeventargs e) { string item = e.item string; if (item != null) { switch (item) { case "1": e.appearance.forecolor = color.green; e.appearance.backcolor = color.green; break; case "2": e.appearance.forecolor = color.orange; e.appearance.backcolor = color.orange; break; case "3": e.appearance.forecolor = color.red; e.appearance.backcolor = color.red; break; } } } when dropdown shown, items forecolor correct, backcolor remains whatever backcolor of theme is; i.e. if i've got set dark theme, backcolor dark, cells in gridview, rather being green/orange/red. i've tried setting e.appearance.options.usebackcolor trying set e....
