ios - Presenting a viewController on SKScene

Question

I am trying to present UIActivityViewController on an SkView but xcode gives me this error :

No visible @interface for 'GameOver' declares the selector 'presentViewController:animated:completion:'

- (void)shareScore {

    //add view
    UIView *Sview  = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 512, 512)];
    UIImageView *image = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"shareScoreImg.png"]];
    image.frame = Sview.frame;
    [Sview addSubview:image];

    //add label
    CGRect fframe = self.view.frame;

    UILabel *score = [[UILabel alloc] initWithFrame:fframe];
    score.text = @"9999";
    score.textAlignment = NSTextAlignmentCenter;
    score.textColor = [UIColor darkGrayColor];
    score.center = CGPointMake(250, 440);
    score.font = [UIFont fontWithName:@"Pixel LCD7" size:50];
    [Sview addSubview:score];


    //capture view
    UIGraphicsBeginImageContextWithOptions(Sview.bounds.size, Sview.opaque, 0.0);
    [Sview.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage * screenshot = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    UIActivityViewController* activityViewController =
    [[UIActivityViewController alloc] initWithActivityItems:@[screenshot]
                                      applicationActivities:nil];

    [self presentViewController:activityViewController animated:YES completion:nil];

}

How can I present preset a viewController on SKScene ? thanks .

Answer 1

We can use "presentModalViewController" by using this code to access the root view controller

 UIViewController *vc = self.view.window.rootViewController;
    [vc presentViewController: activityViewController animated: YES completion:nil];

now it works fine !
