ios - Passing NSString from View Controller to TableViewController -

can please advise on how pass array of nsstrings viewcontroller tableviewcontroller. have tried using prepareforsegue in rootviewcontroller

-(void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender { tableviewcontroller *transferviewcontroller = segue.destinationviewcontroller;  nslog(@"segue %@", segue.identifier);  if ([segue.identifier isequaltostring:@"segueaffiliation"]) {     // segue affiliation happened     transferviewcontroller.titletext = @"friendly";  } else if ([segue.identifier isequaltostring:@"seguecategory"]) {     // segue category happened } else if ([segue.identifier isequaltostring:@"seguefunction1"]) {     // segue function1 happened } else if ([segue.identifier isequaltostring:@"seguefunction2"]) {     // segue function2 happened } else if ([segue.identifier isequaltostring:@"seguefunction3"]) {     // segue function3 happened } 

and not sure on how pass data, far have in tableviewcontroller

@interface tableviewcontroller ()  @end  @implementation tableviewcontroller { nsarray *_tabledata; }  - (id)initwithstyle:(uitableviewstyle)style { self = [super initwithstyle:style]; if (self) {     // custom initialization } return self; }  - (void)viewdidload { [super viewdidload];  // initialize table data  self.celltitle.text = self.titletext; }  - (void)didreceivememorywarning { [super didreceivememorywarning]; // dispose of resources can recreated. }  #pragma mark - table view data source  - (nsinteger)numberofsectionsintableview:(uitableview *)tableview { // return number of sections. return 1; }  - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section { // return number of rows in section. return [_tabledata count]; }  - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath    *)indexpath { static nsstring *cellidentifier = @"cell"; uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:cellidentifier forindexpath:indexpath];  // configure cell...  return cell; } 

you have declare array _tabledata in header file :

@property (strong, nonatomic) nsarray *_tabledata; 

and in .m file :

@synthesize _tabledata; 

currently _tabledata private.
