我正在尝试展示UIActivityViewController，SkView但 xcode 给了我这个错误：
No visible @interface for 'GameOver' declares the selector 'presentViewController:animated:completion:'
'GameOver' 没有可见的 @interface 声明了选择器 '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];

We can use "presentModalViewController" by using this code to access the root view controller
我们可以使用“presentModalViewController”通过使用此代码来访问根视图控制器
UIViewController *vc = self.view.window.rootViewController;
[vc presentViewController: activityViewController animated: YES completion:nil];
now it works fine !
现在它工作正常！

IIRC the first SKScenethat you create is inside an SKView.
SKScene您创建的第一个 IIRC 位于SKView.
This SKViewis inside a UIViewController.
这SKView是在一个UIViewController.
You can use properties or delegation or whatever you like to access methods on the UIViewControllerthrough the SKViewfrom the SKScene. Or even use a notification.
您可以使用属性或委托或任何您喜欢的方式来访问UIViewController通过SKViewfrom 的方法SKScene。或者甚至使用通知。
Then on the UIViewControlleryou can present the new view controller with no problems.
然后，UIViewController您可以毫无问题地展示新的视图控制器。
