ios - Cannot delete files from Dropbox(from iPhone app) -

-

i'm trying delete files dropbox. have implemented swipe delete behaviour. 'swipe-delete' deletes files tableview only. next time upload, can see 'deleted' files , when check dropbox account on pc, files never deleted. they're there after file disappears tableview.

- (uitableviewcelleditingstyle)tableview:(uitableview *)tableview   editingstyleforrowatindexpath:(nsindexpath *)indexpath  {           return uitableviewcelleditingstyledelete;   }  - (void)tableview:(uitableview *)atableview commiteditingstyle:(uitableviewcelleditingstyle)editingstyle forrowatindexpath :(nsindexpath *)indexpath  {                     [self.itemarray  removeobjectatindex:indexpath.row];              [atableview deleterowsatindexpaths:[nsarray arraywithobject:indexpath] withrowanimation:yes];      [self.tableview reloadsections:[nsindexset indexsetwithindex:0]withrowanimation:uitableviewrowanimationfade];      }

you're code shows you're deleting entry table view. there no code deletes file system, eg. using 

[[nsfilemanager defaultmanager] removeitematpath:filepath error:&error];
