ios - Converting fetchedResultsController into NSArray? -

i using (somessaging) https://github.com/socialobjects-software/somessaging

i want use code core datas fetchedresultscontroller

the problem when implementing messagesviewcontroller code above must return nsarray of messages this:

- (void)viewdidload {     [super viewdidload];     // additional setup after loading view.      self.myimage      = [uiimage imagenamed:@"arturdev.jpg"];     self.partnerimage = [uiimage imagenamed:@"jobs.jpg"];       [self loadmessages]; }  - (void)loadmessages {     self.datasource = [[[contentmanager sharedmanager] generateconversation] mutablecopy]; }    - (nsmutablearray *)messages {     return self.datasource; } - (void)configuremessagecell:(somessagecell *)cell formessageatindex:(nsinteger)index {     somessage *message = self.datasource[index];      // adjusting content 3pt. (in demo width of bubble's tail 3pt)     if (!message.fromme) {         cell.contentinsets = uiedgeinsetsmake(0, 3.0f, 0, 0); //move content 3 pt. right         cell.textview.textcolor = [uicolor blackcolor];     } else {         cell.contentinsets = uiedgeinsetsmake(0, 0, 0, 3.0f); //move content 3 pt. left         cell.textview.textcolor = [uicolor whitecolor];     }      cell.userimageview.layer.cornerradius = self.userimagesize.width/2;      // fix user image position on top or bottom.     cell.userimageview.autoresizingmask = message.fromme ? uiviewautoresizingflexibletopmargin : uiviewautoresizingflexiblebottommargin;      // setting user images     cell.userimage = message.fromme ? self.myimage : self.partnerimage; }    example calls function generate sample messages:  - (nsarray *)generateconversation {     nsmutablearray *result = [nsmutablearray new];     nsarray *data = [nsarray arraywithcontentsofurl:[nsurl fileurlwithpath:[[nsbundle mainbundle] pathforresource:@"conversation" oftype:@"plist"]]];       (nsdictionary *msg in data) {         somessage *message = [[somessage alloc] init];         message.fromme = [msg[@"fromme"] boolvalue];         message.text = msg[@"message"];         message.type = [self messagetypefromstring:msg[@"type"]];         message.date = [nsdate date];          int index = (int)[data indexofobject:msg];         if (index > 0) {             somessage *prevmesage = result.lastobject;             message.date = [nsdate datewithtimeinterval:((index % 2) ? 2 * 24 * 60 * 60 : 120) sincedate:prevmesage.date];         }          if (message.type == somessagetypephoto) {             message.media = uiimagejpegrepresentation([uiimage imagenamed:msg[@"image"]], 1);         } else if (message.type == somessagetypevideo) {             message.media = [nsdata datawithcontentsoffile:[[nsbundle mainbundle] pathforresource:msg[@"video"] oftype:@"mp4"]];             message.thumbnail = [uiimage imagenamed:msg[@"thumbnail"]];         }          [result addobject:message];     }      return result; } 

meaning messages in message array have somessage objects.

i want use core data im going using fetchedresultscontroller how can load data fetchedresultscontroller.

i dont want start converting nsarray because im not sure happen when more data added , data reloaded.

would great if give me code examples out.

if want see full code available on github can see how works.
