Condition doesn't work

I use button in ViewController to go TableViewController. In TableViewController I create int NInt1. But when I go to TableViewController condition doesn't work.

ViewController.m

- (IBAction)Button:(id)sender {
MasterViewController *trns =[[MasterViewController alloc]init];
[_Button.titleLabel.text isEqualToString:@"1"];
    trns.NInt1=1;
}

TableViewController.m

 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if(_NInt1 == 1){
    return 5;
}else{
    return 20;
}
}

I tried the solution.Finally I got.Thank you.The condition has worked now.

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
  if([segue.identifier isEqualToString:@"goTableViewController"])
  {
    TableViewController *tableVC = (TableViewController *) segue.destinationViewController;
    tableVC.NInt1 = 5;
  }
}

If you use storyboard, then the destination view controller is not created from your IBAction. It can be verified easily : you never push or present the newly created view controller, which is local in your method.

Instead use prepareForSeguemethod as described in Jaimish answer.

If you are using the story pass the value like this:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    RecipeDetailViewController *destViewController = segue.destinationViewController;
    destViewController.NInt1 = 1;
}

Now see the value of NInt in viewDidLoad of your destination view controller.

I think you need to modify like 

- (IBAction)Button:(UIButton *)sender {
 MasterViewController *trns =[[MasterViewController alloc]init];
if [sender.titleLabel.text isEqualToString:@"1"]{
  trns.NInt1=1;
 }
}

on that tableviewController viewDidload check like use NSLog for the object is 1 or not
