ios - Magical Record, delete from UITableView "invalid number of rows in section 0..." -

i'm using magical record manage coredata. when user delete specific cell in table, is:

set flag , delete row table:

- (void)tableview:(uitableview *)tableview commiteditingstyle:(uitableviewcelleditingstyle)editingstyle forrowatindexpath:(nsindexpath *)indexpath { [tableview beginupdates]; if (editingstyle == uitableviewcelleditingstyledelete) { messagetableviewcell *cell = (messagetableviewcell *)[tableview cellforrowatindexpath:indexpath]; nsarray *sortedmessageid = [cell.photodetails.message.message_id componentsseparatedbystring:@"_"]; nsstring *messageid = sortedmessageid[1]; nslog(@"cell.photodetails.message.message_id: %@", cell.photodetails.message.message_id); nslog(@"sortedmessageid: %@", sortedmessageid); nsassert(sortedmessageid[1] != nil, @"sortedmessageid[1] cannot nil."); nsassert(messageid != nil, @"messageid cannot nil."); if (cell.photodetails) { [magicalrecord savewithblockandwait:^(nsmanagedobjectcontext *localcontext) { cell.photodetails.message.delete_message = @yes; }]; } // [self.datasource removeobjectatindex:indexpath.row]; [tableview deleterowsatindexpaths:@[indexpath] withrowanimation:uitableviewrowanimationautomatic]; [self performselectorinbackground:@selector(deletemessagesfromserver:) withobject:messageid]; } [tableview endupdates]; }

update server ids delete, server send ids , if match, delete them coredata:

@try { treenode *root = [treenode treenode]; xmlparser *parser = [[xmlparser alloc] init]; root = [parser parsexmlfromdata:data]; if (root.key && [root.key.lowercasestring isequaltostring:@"messages"]) { (treenode *children in root.children) { if ([children.key.lowercasestring isequaltostring:@"message"]) { (treenode *children2 in children.children) { if ([children2.key isequaltostring:@"id"]) { nspredicate *predicate = [nspredicate predicatewithformat:@"message.message_id ==[c] %@", children2.leafvalue]; bool isdelete = [coredataphotorecord mr_deleteallmatchingpredicate:predicate]; [[nsmanagedobjectcontext mr_defaultcontext] mr_saveonlyselfandwait]; nslog(@"%s, isdelete: %@", __pretty_function__, @(isdelete)); } } } } nslog(@"allacceptedrecords.count: %lu", (unsigned long)[humanresponse allacceptedrecords].count); // nslog(@"allacceptedrecords.count: %lu, self.datasource.count: %lu", // (unsigned long)[humanresponse allacceptedrecords].count, (unsigned long)self.datasource.count); } } @catch (nsexception *exception) { nslog(@"%s, exception.reason: %@", __pretty_function__, exception.reason); }

additional code:

- (nsinteger)numberofsectionsintableview:(uitableview *)tableview { homecoming 1; } - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section { // homecoming self.datasource.count; homecoming [humanresponse allacceptedrecords].count; } + (nsarray *)allacceptedrecords { homecoming [coredataphotorecord mr_findallsortedby:@"message.originaldate" ascending:no withpredicate:[nspredicate predicatewithformat:@"message.delete_message == %@", @no]]; }

what doing wrong?

as sebastian wramba suggested, changed way i'ms aving context:
