SpriteKit + xcode6当前场景崩溃应用程序

Question

我正在创建一个简单的MainMenu场景，在“播放”按钮上选择我移动到游戏场景如下：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {    
    for (UITouch *touch in touches) {
        CGPoint location = [touch locationInNode:self];
        SKNode *node = [self nodeAtPoint:location];

        if ([node.name isEqualToString:@"play"]) {

                SKScene *gameScene  = [[GameScene alloc] initWithSize:self.size];
                SKTransition *fadeTransition = [SKTransition fadeWithColor:[UIColor blackColor] duration:0.3];
                [self.view presentScene:gameScene transition:fadeTransition];


        }

    }
}

在过渡之后，应用程序与EXC_BAD_ACCESS (code=1)崩溃。我目前正在运行Xcode6 +SpritKit/Objective

发现了这个问题--显然是由粒子targetNode分配引起的：

starParticle.targetNode = self.scene;

可能在呈现其他场景之前就应该发布
