Confused by earlier errors - Bailing out

I am getting an unusual error whe开发者_运维百科n I try building or running my iphone game.

//GameScene.mm

- (void) onExit  
{  
    if(!([SimpleBox2dScrollerAppDelegate get].paused))  //error comes here
    {  
        [SimpleBox2dScrollerAppDelegate get].paused = YES;  
        [super onExit];  
    }   
}  

// SimpleBox2dScrollerAppDelegate.mm

+(SimpleBox2dScrollerAppDelegate *) get {  

    return (SimpleBox2dScrollerAppDelegate *) [[UIApplication sharedApplication] delegate];  
}  

What might be the reason?
