Passing an int to a new ViewController

Ive spent a month trying to pass my int to a new view. My int is called score and is connected to a label called scorelab. The user increases the score and once the they run out of time game switches views to game over screen and i would like the users score to be displayed on the game over screen in a label. The game play controller is called GamePlayViewController and the gave over controller is called GameDidEndViewController. I'm tired of trying to get this to work. I have looked at every tutorial possible but nothing seems to work for my case. Please help me i would appreciate it so so much, this is the very last part of game that I need to finish. Thank you in advance!

Sorry here is the code:

GamePlayViewController.h

#import "GameDidEndViewController.h"


int score;

IBOutlet UILabel *scorelab;

GamePlayViewController.m

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{

if ([[segue identifier] isEqualToString:@"GameOver"])
{

    GameDidEndViewController *vc = [segue destinationViewController];

    [vc setscore2: score];
}
}

GameDidEndViewController.h

#import "GamePlayViewController.h"
IBOutlet UILabel *scorelab2;
int score2;
}
@property (nonatomic , assign) int score2;
@property (nonatomic , assign) UILabel *scorelab2;

GameDidEndViewController.m

@synthesize score2 , scorelab2;
-(void)viewWillAppear:(BOOL)animated {
scorelab2.text = [NSString stringWithFormat: @"%d", score2];
[super viewWillAppear: animated];  
}

Here is some tutorial for passing data between ViewControllers using Storyboard:

  1. Storyboards Segue Tutorial: Pass Data Between View Controllers
  2. Tutorial on How-To Pass Data Between Two View Controllers

or use something like this:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:...]) {
        MyViewController *controller = (MyViewController *)segue.destinationViewController;
        controller.score = score;
    }
}

Hope this helps.

What you do is create a property in GameDidEndViewController to hold the passed in score value.

@interface GameDidEndViewController : UIViewController {

....
}
@property(nonatomic,assign) int score;
@end

Make sure you @synthesize score in the @implementation(.m).

Now when you init and show the GameDidEndViewController you set the score, likely something like this.

GameDidEndViewController *end = .....// init the view.
end.score = score; // assuming you're doing this from GamePlayViewController where it has an int named `score`

Hope this helps !
