Ios7 如何从UIViewController移动到myScene？

我有两个viewcontroller。在第一个viewcontroller中，有游戏的介绍和徽标，在第二个viewcontroller中加载场景。我通过点击按钮从第一个viewcontroller移动到第二个viewcontroller。但这是一个错误。我的代码在第二个视图中控制器是：

@interface MPAPViewSceneController()

@property (nonatomic, retain) MPAPMyScene *targetScene;
@property SKView *spriteView;
@end



- (void)viewDidLoad
{
  [super viewDidLoad];

 _spriteView = (SKView *)self.view;
 _spriteView.showsFPS = YES;
 _spriteView.showsNodeCount = YES;
 _spriteView.showsDrawCount   = YES;
}

-(void)viewWillAppear:(BOOL)animated {
  self.targetScene = [[MPAPMyScene alloc] initWithSize:CGSizeMake(768.0f, 1024.0f)];
 [_spriteView presentScene:self.targetScene];
}

 -(void)viewDidDisappear:(BOOL)animated 
{
  [super viewDidDisappear:YES];
  self.targetScene = nil;
}

在场景中，我编写了以下代码：

@interface MPAPMyScene()

@property (nonatomic) BOOL contentCreated;

@end

@implementation MPAPMyScene

-(void)didMoveToView:(SKView *)view {
if (self.contentCreated == NO) {
    [self createSceneContents];
    self.contentCreated = YES;
}
}



-(void)willMoveFromView:(SKView *)view {
[self removeAllChildren];
}


-(void)createSceneContents {
self.backgroundColor = [UIColor blueColor];
self.scaleMode = SKSceneScaleModeAspectFit;
}

试着改变这个

_spriteView = (SKView *)self.view;

这应该有助于你忘记提及你所犯的错误。链接答案帮助我解决问题。

_spriteView = (SKView *)self.targetScene;
