Add Cell in the Table View Controller - ios

Question

In my application, there's a Navigation View(Embed In), a Table View Controller, and a View Controller. And in the ViewController.h, there are...
#property (strong, nonatomic) IBOutlet UILabel *timeDisplay;
#property (strong, nonatomic) IBOutlet UILabel *minuteDisplay;
#property (strong, nonatomic) IBOutlet UILabel *timerDisplay;
#property (strong, nonatomic) IBOutlet UILabel *titleLabel;
and more outlets. The code below is TableViewController.m file. I have a action button(plusbtn), which needs to add a cell in the table view. So, I tried to make the 'plusbtn' do it, but it didn't work. What should I do? Please help me...
#import "TableViewController.h"
#import "TableViewCell.h"
#import "ViewController.h"
#interface TableViewController ()
#property (nonatomic) ViewController *viewController;
#property (strong, nonatomic) NSMutableArray *titleArray;
#property (strong, nonatomic) NSMutableArray *tsArray;
#property (strong, nonatomic) NSMutableArray *tmArray;
#property (strong, nonatomic) NSMutableArray *ttArray;
#property (strong, nonatomic) NSString *cellplustitle;
#property (strong, nonatomic) NSString *cellplustime;
#property (strong, nonatomic) NSString *cellplusmin;
#property (strong, nonatomic) NSString *cellplussec;
#end

_cellplustitle = self.viewController.titleLabel.text;
_cellplustime = self.viewController.timeDisplay.text;

self.titleArray = [NSMutableArray new];
self.tsArray = [NSMutableArray new];
self.tmArray = [NSMutableArray new];
self.ttArray = [NSMutableArray new];
// Uncomment the following line to preserve selection between presentations.

Answer 1

ReloadData should work. If its not working if you put if between beginUpdate and endupdate, then comment rest code and simply try to reload table view after adding item in array. Like...
- (IBAction)plusbtn:(id)sender {
[self.titleArray addObject:self.cellplustitle];
[self.tsArray addObject:self.cellplussec];
[self.tmArray addObject:self.cellplusmin];
[self.ttArray addObject:self.cellplustime];
[self.tableview reloadData];}
Hope this helps?

Answer 2

you have to reload the uitableview using
[self.tableView reloadData];
Hope it helps!
