Sprite kit xcode6模拟器中的精灵套件测试

我的问题是，当我想用“SKPhysicsBody”来检测我正在触摸的spritenode时，它在xcode6模拟器中返回“nil”，代码如下

初始化

触摸检测

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
/* Called when a touch begins */
for (UITouch *touch in touches) {
    CGPoint touchLocation = [touch locationInNode:self];
    NSLog(@"%f",touchLocation.x);
    SKPhysicsBody* body = [self.physicsWorld bodyAtPoint:touchLocation];
    NSLog(@"%@",body.node.name);
    if ([body.node.name isEqualToString:@"start"]){
        NSLog(@"go");
        [audioPlayer stop];
        [[NSNotificationCenter defaultCenter] postNotificationName:@"nameHide"object:@"Hide"];

        SKScene *spaceshipScene=[[SpaceshipScene alloc]initWithSize:self.size];
        SKTransition *doors=[SKTransition doorsOpenVerticalWithDuration:0.5];
        [self.view presentScene:spaceshipScene transition:doors];

    }
}

}

NSLog（@“%@”，body.node.name）返回
nil
。
有什么问题，请提前感谢。
尝试在节点之间循环。在最后一个Xcode 6 GM中，这与Xcode 5不同。
我也有同样的问题，我就是这样解决的。
在您的情况下，将代码更改为：

    NSArray *nodes = [self nodesAtPoint:touchLocation];
        for (SKNode *n in nodes){

 if ([n.name isEqualToString:@"start"]){
        NSLog(@"go");
        [audioPlayer stop];
        [[NSNotificationCenter defaultCenter] postNotificationName:@"nameHide"object:@"Hide"];

        SKScene *spaceshipScene=[[SpaceshipScene alloc]initWithSize:self.size];
        SKTransition *doors=[SKTransition doorsOpenVerticalWithDuration:0.5];
        [self.view presentScene:spaceshipScene transition:doors];

    }
}

我已经在我的设备（ios7.1）上进行了测试，这两种方法都可以工作，也许在ios8中只能循环通过节点？是的，我认为在ios8中必须循环以确保选择正确的节点。
    NSArray *nodes = [self nodesAtPoint:touchLocation];
        for (SKNode *n in nodes){

 if ([n.name isEqualToString:@"start"]){
        NSLog(@"go");
        [audioPlayer stop];
        [[NSNotificationCenter defaultCenter] postNotificationName:@"nameHide"object:@"Hide"];

        SKScene *spaceshipScene=[[SpaceshipScene alloc]initWithSize:self.size];
        SKTransition *doors=[SKTransition doorsOpenVerticalWithDuration:0.5];
        [self.view presentScene:spaceshipScene transition:doors];

    }
}
