ios - How to get values for object in didChangeObject:(id)anObject (NSfetchedResultsController) -

how can access object actual values in fetchedresultscontroller delegate method ?

i want set section of indexpath rows delete/change according values of object, table has multiple datasources

- (void)controller:(nsfetchedresultscontroller *)controller didchangeobject:(id)anobject   atindexpath:(nsindexpath *)indexpath forchangetype:(nsfetchedresultschangetype)type   newindexpath:(nsindexpath *)newindexpath  { ....get objects value, e.g. myentity.city  } 

now know object of class myentity (at least ultimately, not sure "anobject" refers to), compiler complains when want set instance of myentity *anentity = anobject;

my workaround has been put data each section arrays, , work in tableview:commiteditingstyle:forrowatindexpath: know section called , need access indexpath.row. drawback have reload arrays after each change , can not directly work fetchedresultscontroller.

edit: accepted answer works fine, shortcut seems work purpose:

nsstring *astring = [anobject valueforkey:@"city"];  

the compiler complain, it's warning because haven't told expect. it's simple as:

myentity *anentity = (myentity *)anobject; 

that said, need sure it's correct class, pays add little protection:

if ([anobject iskindofclass:[myentity class]) {     myentity *anentity = (myentity *)anobject;     // stuff } else {     nslog(@"panic / cry / plead"); }
