i've been trying add object in array. here's i've done far:

nsmutablearray *mutablemenuarray = [nsmutablearray arraywitharray:dictionary[mjfeeddatakey]]; [mutablemenuarray removeobjectatindex:1]; [mutablemenuarray removeobjectatindex:1];  nsmutablearray *menuarray = [[nsmutablearray alloc] init]; [menuarray addobjectsfromarray:mutablemenuarray]; [menuarray addobject:@"check"];  mjmenuentities *menus = [mjmenuentities sharedinstance]; [menus setwitharray:menuarray]; self.modelarray = [nsmutablearray arraywitharray:menus.menuitems];

but once i've set menus menuarray comes error:

"terminating uncaught exception of type nsexception on nsarray".

but if menus set mutablemenuarray there no error.

nsarray immutable. seems modify first parameter of method:- setwitharray.
