Xcode says that the "shouldAutorotate" code is undeclared. But I don't write this code. It is supplied by Apple, isn't it. This is the code:

SKView * skView = (SKView *)self.view;

skView.showsFPS = YES;

skView.showsNodeCount = YES;

/ Sprite Kit applies additional optimizations to improve rendering performance */

skView.ignoresSiblingOrder = YES;

/

GameScene *scene = [GameScene nodeWithFileNamed:@"GameScene"];

scene.scaleMode = SKSceneScaleModeAspectFill;

/

[skView presentScene:@"scene"]; //Another error:"incompatible pointer types sending 'NSString*' to parameter of type 'SKScene _Nullable'"

- (BOOL)shouldAutorotate{ // Error in this line :"Use of undeclared identifier 'shouldAutorotate' "

return YES;

}

Please help me. Thank you.

Seems that shouldAutororate is now a property and no more a func.

So you should override the var shouldAutororate.

Thanks for the explanation and the website. But the code of the website is in Swift and I am using Objective C. Sorry I didn't tell you before. And I understand some of them but not all. Do you have other explanations? Thank you

I'm not fluent in objC, so I can only post what I read :

to override a property accessors :

- (void)setHidden:(BOOL)hidden {
    super.hidden = hidden;
    [self invalidateIntrinsicContentSize];
}

Accepted Answer

I've compiled the boolean in the viewDidLoad method. So I moved it out and the error is fixed. Thanks for help
