how link row in tableView to a segue - ios

Question

I have two viewControllers, ViewController and TableViewController. the ViewController has a button, when pressed the TableViewController will start. the TableViewContoller contains 5 rows.
what I am trying to do is, when I press only the even rows I should go back to ViewController. To solve this problem, we can use unwindSegue, but I do not know how to have the segue respond to the even rows in the table.
please let me know how to make a row in the table linked to the segue
below is the code for TableViewController
code:
#import "TableViewController.h"
#interface TableViewController ()
#property NSArray *tableData;
#end
#implementation TableViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.tableData = [NSArray arrayWithObjects:#"Android",
#"iOS",
#"swift",
#"objective-c",
#"openCV",nil];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:
(NSInteger)section {
return [self.tableData count];
}
-(UITableViewCell *) tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *simpleTableIdentifier = #"SimpleTableItem";
UITableViewCell *cell = [tableView
dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:simpleTableIdentifier];
}
cell.textLabel.text = [self.tableData objectAtIndex:indexPath.row];
cell.imageView.image = [UIImage imageNamed:#"images.jpg"];
return cell;
}
-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:
(NSIndexPath *)indexPath {
NSLog(#"%li", indexPath.row);
NSLog(#"%#", [self.tableData objectAtIndex:indexPath.row]);
}
#end

-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:
(NSIndexPath *)indexPath {
if(indexPath.row % 2 == 0) {
// Even row...
}
}
