SpriteKit + xcode6呈现场景崩溃应用

Question

我正在创建一个简单的MainMenu场景并在＆＃34; play＆＃34;按钮选择我按如下方式移动到游戏场景：

-(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];


        }

    }
}

转换应用程序崩溃后，EXC_BAD_ACCESS（代码= 1）。我目前正在运行Xcode6 + SpritKit / Objective-C

发现问题 - 显然是由粒子targetNode赋值引起的：

starParticle.targetNode = self.scene;

可能应该在呈现其他场景之前发布
