Answer 1

you can follow some simple steps to make it working.

1. First View: add the following code in your didSelectRowAtIndexPath method of tableview

-(void)tableView:(UITableView *)tableViewdidSelectRowAtIndexPath:(NSIndexPath *)indexPath
  {
    //Fetch the value of the selected row in NSString

    NSString *tableRowValue = cell.textLable.text;


    //Call the next view

    secondView *secondViewController = [[secondVIew alloc] initWithNibName:@"secondView" bundle:nil];

    secondViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve ;

    //Initialize the view with the clicked row value thwough NSString variable 
    [secondViewController initializeWith:tableRowValue];

  }

2.Second View:

In your .h file, add the following initialization method:

-(void)initializeWith:(NSString *)sentRowValue;

IN your .m file, implement the initilization method:

-(void)initializeWith:(NSString*)sentRowValue
  {
      NSString *receivedRowValue = sentRowValue;
      //take log to check 
  }


// now perform all the table view delegate methods using the value you have received.

NOTE: declare all the variables in your .h file and make them as property and synthesize them in your .m file

hope this helps
