ios - itunes file share restore deleted files -

my app uses itunes file share. used code delete single file: worked first time. on second try, however, itunes showed empty share directory. turns out data files gone. can recover data files ipad? thanks

- (void) deletefilefromdisk: (nsstring*) filename {   if([self fileexists: filename])  {         nsarray *paths = nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes) ;         nsstring *documentsdirectory = [paths objectatindex: 0];         nsstring* thefile = [documentsdirectory stringbyappendingpathcomponent: filename];         nserror *error;         [[nsfilemanager defaultmanager] removeitematpath: thefile error: &error]; 

there's no "restore" feature on ipad. in probability there's nothing worry about.

there's nothing code delete multiple files. delete file documents directory supplied name of filename. if didn't call deletefilefromdisk: multiple times, didn't delete multiple files.

perhaps @ point deleted app. delete entire sandbox , take in documents directory. sort of thing normal during repeated testing.
